Ford 460 engine Marcel 6-15-09  
We have a 1994 E350 Class C motorhome,
460 engine. Hesitates/jerks while driving along,this does not seem to happen when pulling hard. Could it be fuel filter,fuel pump, transmission, shifting problems? This happens in all types of weather. Another problem..in hot weather truck won't run, have been told it is vapor lock, when we let it cool off problem seems solved. Any suggestions to the above questions.

Re: Ford 460 engine Al Barrs 6-12-10  
1987 Fleetwood Jamboree 26 ft Class C Motorhome on E-350 Ford Chassis, Gas Carburetored with 40 gal gas tank behind rear axle with single in-tank fuel pump and inline gas filter attached to driver side frame. Have replaced both in-tank fuel pump and inline filter.

After unit sits for a while it takes forever to start the engine. The fuel either leaks out of the carb or back into the gas tank, or something else is not working properly. Once the engine does start it runs fine. I am worried about burning out the starter, so stop between a few seconds spin to let it cool. Also worry about running the battery down.

What's my problem and fix?

Thanks,

I have a 1986 F-250 Ford truck with the 460 V-8. It was equipped with an oil cooler which developed a serious leak. My mechanic replaced it with a different oil filter which eliminated the oil cooler. A new oil pump was also installed. Now there is no oil pressure to the top half of the engine. The pump fills the oil filter but does not get up any pressure. This truck sat for a long time before doing this work. Could there be oil passages that are clogged with sludge and stopping the pressure?

I have a 1986 E350 with 460 engine. The transmission only on occasion will shift to Overdrive. Does anyone know what the corrective measures would be to fix this condition? Is there a speed sensor in this make and year of transmission?
Re: Ford 460 engine Marcel 4-9-10  
Re: Posting from July 14/09
Just to clarify what was done to our unit that has fixed the problem.
MLPS switch was replaced. A leaking 10UF capacitor in the ECM unit was replaced as well. Works great.

Battery is getting drained with no cause. Hook up new bat. and it turns over with no key in ignition key in locked position. replaced ignition switch. Changed selnoid 3 times in last 4 months and still has problems. Anyone out there that can help? It would be muchly appreciated.
Re: Ford 460 engine scott 6-3-10  
Hello,
me again reporting back on the note above:

I took the truck out yesterday on the Left saddle tank which has it's own fuel filter.

Although I didn't have load on the truck I pushed harder than normal and did not have a sputter.

Saturday I will replace all three fuel filters and come next weekend I will head for Ski Valley Palm Springs area and test the truck under load.

I have to make sure this problem is fixed before the long trip to Big Sir,
El Capitan Beach and so on..

I will keep posted on this issue.

1992 Ford 460 Motorhome class c Linda 2-15-11  
When I drive between 35 and 45 mph I get a vibration from the motor. Sitting idle I can smell the gas fumes as if it was running rich. When I hit 50 mph it seems to smooth out, but not perfect. Any suggestions?

I HAVE A 1994 E 350 SHUTTLE BUS. IT MISFIRES SPUTTERS AT IDLE THEN ONCE THE VEHICLE GETS UP TO OPERATING TEMP IT WILL NOT SHIFT INTO SECOND GEAR AND SPUTTERS SO BAD YOU CAN BARELY GO 15 MPH. I HAVE CHANGED: FUEL FILTER, TEMP SENSOR, COIL, SPARK MODULE, CPS, CAP ROTOR, WIRES, I HAVE CHECKED FUEL PRESSURE, EGR, CAT, AND O2 SENSORS I ALSO DRAINED THE TANK COMPLETLY AND PUT NEW FUEL AND ANOTHER FUEL FILTER. THIS VEHICLE SAT FOR 2 YEARS AND I AM STUMPED ON WHAT TO DO NEXT.

Re: Ford 460 engine donny 3-12-11  
I purchased a 1986 Ford motorhome and i cant seem to get it to run as it should. It will not start unless I remove the breather and manually choke it with my hand...The previous owner purchased a new 4 barrel holley carb several people has advise me to remove the holley and replace it with a elderbrock.This has the 460 big block it only has 36000 k...so can anyone help me with this if so..what should i ask for when purchasing a new carb...
Thanks for your help!

My truck is having this on going poblem. Ive taken to the shop many times to no avail please help.Tack goes crazy as im driving it.it sputters and stalls.recently in hot weather, it will misfire,stall& will notstart up again after being turned off. What is the problem.
Re: Ford 460 engine MikeD 10-16-09  
I have fought the fuel wars with my coach for 10 years. I think the design is a poor one.

There is a sock filter on the fuel pump in the tank that gets dirty and can cause the problem. It only comes with a new fuel pump. So drop your tank, pull the pump and clean the sock with some kind of solvent and blow clean.

Re: Ford 460 engine Marcel 8-28-09  
Marcel here once again..just got back from an 1,800 mile road trip and our motorhome with the Ford 460 engine worked great..not a hesitation or sputter or burp the entire trip. Our problem is fixed,see my post of:7-14-09
Good luck to all...hope this helps.

Re: Ford 460 engine John 7-22-09  
I have an 88 Winnebago with 460 w/4bbl carb. Most of the time I go to start it and it cranks good but no start. Sometimes it starts, but I don't see a pattern to it. Put my timing light on tonight and there is no spark while cranking. Replaced the wires, cap, rotor, plugs. What's next? Module? Pickup?
Also, when I go to look for parts online (e.g. Autozone) the latest 460/4bbl listed is 1986, then they only list the fuel injected engines. Should I be looking for parts for a 1986 to fit my 88?
Re: Ford 460 engine Marcel 7-14-09  
Marcel here again. Just picked up the motorhome this AM and this is what the mechanic did:
Diagnosis engine"miss and hesitation"...performed a lab scope test on MAP sensor. Check spout and PIP signals, scope pattern showed A/C circuit spikes on MLP sensor circuit.Replaced the MLP sensor and had his friendly TV repairman fix the leaking capacitor. Works great on the trip home. Going on a long road trip and that will be the test.
Have a good feeling about this, hope this helps others.... Marcel
Re: Ford 460 engine BUBBA THE BUS TECH 6-16-09  
OK to diagnose: find the fuel pump relay and figure out how to bypass it. Second figure out how to do an easy check for spark. I have been left the dog house loose so I could yank it in a hurry for this. When it quits, Check for spark. If it has spark hot wire the fuel pump and see if it runs. If no spark you have a bad pick up, module or if its all integrated into the engine computer perhaps one of those. The pickup and module are most likely as they take the most heat punishment. The fuel pump relay should not be run hot wired as it is an important safety item! The computer controls that, and you will need to figure out if the control system (Computer and wiring) works or the relay is bad. (Cheap and Easy fix) The Fuel pump itself may be bad. Look at all the Dodge Mini vans sitting beside the road first really warm day of summer. My freind in the parts buisness sells out almost every spring. Good luck

Re: Ford 460 fi engine Bill 9-4-09  
I have a 1990 Ford 460fi Cobra Motorhome, F-53 chassis. 54,000 miles. It runs great except for a slight speed increase with slight pressure on the accel, or going up a slight incline. It is as if it is changing a half gear between O/D and Drive hardly noticeable.(not a gear change) It does need a new thermostat, would that make a difference? Also it has a new c-6 tranny. When I let up the speed lowers slightly. What would you suggest I check? Thanks.

Re: Ford 460 engine Tom 9-22-11  
1994 E350 miss fire.
Changed all the wires plugs and etc no difference. Problem resolved with MARCEL's 4-9-10 fix. Changed the 10MFD polarized electrolitic capacitor in the ECM. There are three capacitors in the ECM one 10 MFD and two 47 MFDs. No need to change the 47 MFDs. Make sure you solder in the new one the same way as the old one. The positive wire is indicated by a black stripe on the capacitor. The old capacitor was rated at 16v. I used one rated at 160v. Its just a little bigger but works the same. If your not used to soldering circuit boards get someone that is.
Marcel, thanks so much for your invaluable fix.

Hello Marcel!
Just wanted to thank you for your post. I too have a class C with an E350 that was hesitating and stuttering. Just like your description.

I started with replacing the wires and spark plugs to no avail. When I read your post I pulled my computer and sent it away to get fixed.

It worked! It runs great!

Thank you again,

Re: Ford 460 engine mark 7-6-12  
I have a 94 motorhome with 460 engine.
The engine starts fine and idles fine for about the first minute then starts to idle rough. Sometimes it seems like the engine will die, but it keeps going. Driving at low speeds it misfires fairly often. At higher speeds it runs better but misfires every so often.
I've replaced plugs and wires.
If you have any advice, please let me know.

I have a 1997 Ford E-350 7.5L motorhome that 50% of the time howls at idle. I can kick the pedal and it will go away. Many times when I let off the gas to idle it will do the same thing even though I am moving. I can't find the source of the problem. I changed to a K&N air filter and checked for obstructions. Any ideas?

I have a 1994 winnebago rats chewed some plug wires and vacuum lines. I have replaced cap rotor plugs wires and all vacuum lines. I did a self eec test and code 5-3-6 Brake on off open or shorted to ground. Engine runs great until you put it in any gear. Then when you try to go feels like a brake is stuck on. Is there a wire under the hood that the rat could have chewed that would cause this problem. There was no problem with vehicle until the rat problem. Hope you have some imput
Re: Ford 460 engine Chris 10-13-09  
I have a 1993 Ford Minnie Winnie DL (460). Never had a problem with it starting and running until today (30 days after i drove it 30 miles). Now it will start good, but only run for 2-3 seconds and then die. If i manually push the gas pedal it will run, but it has a loping about it (up and down) on the down side it dies.
Just put a fuel pump on 2000 miles ago, replaced fuel filter, plugs, wires, dist. cap/rotor and still the same problem. Can you please help give some suggestions.

Re: Ford 460 engine Rhonda 7-5-11  
I have a ford E-350 RV with a 460 in it. It has some sort of fuel system problem. If you spray the carborator it runs for about a min. or two them dies out. I replaced the fuel pump in the engine, the filters and checked all the lines. Besides the pump in the gas tank is the anything else I should be doing?? I have a very sick daughter and need this RV fixed asap to get to Ga.from RI. She has two little children that need my help. We are short on cash and time so any help would be greatly appreciated.
Re: Ford 460 engine karl lightford 4-22-13  
I had this problem and it drove me crazy. I finally put in a 1-6 psi fuel pump on the rail under the drivers door and it started right up and runs great. The problem was that the after market fuel sending unit in the after axle tank was not having enough pressure to get the fuel to the front quickly enough to keep up with the carberator demand. There is one other thing it could be. On the back of the engine on top there is a oil pressure sending unit. It has two wires, It is bypassed in the crank mode but once it it starts if that thing is bad and don't send the signal that there is sufficient oil pressure it will cut off fuel flow. Once you turn key off and back on your in crank mode again so it will start. It is not that expensive really for either part. The fuel pump is made by Mr. Gasket and can be bought in any parts store. The sending unit is more difficult to find but I found that oriellys could order it for me and I had it in a couple days. Be sure to take the sending unit to the store with you and they will have to go to old school way of finding things. By that I mean they will have to look it up in the books not the computer. My RV is a 1986 ford Lindy but it has the exact same motor as yours. GOOD LUCK!!!

Re: Ford 460 engine Tom 9-22-11  
Ford E350 miss fire.
Changed all the wires, plugs and etc no change.
Performed Marcel's fix (4-9-10).

Changed the 10 MFD capacvitor in the ECM. There are 3 capacitors in the ECM. One 10 MFD and two 47 MFD. No need to change the 47 MFDs. I bought a polarized 10 MFD 160 volt rated capacitor (voltage rating can be anything greater than 16 volts). The positive wire is indicated by a stripe on the capacitor. I belive the old one was rated at 16 volts. Make sure you solder in the new one with the stripe in the same place as the old one. If your not comfortable soldering circuit boards, get someone to help you.
MAERCEL, thanks for your priceless solution.
Re: Ford 460 engine Scott 6-1-10  
Hello,
I have a F250 1987 460 carb.

I think I may have fuel filter problem
when pulling the Fifth wheel trailer experienced a sputter when accel on the freeway to increase my speed over 60MPH.

It put a scare in me because, I was too far away from home. As I let off the gas and maintained speed at 60MPH.. No problem I drove a bit longer on that tank again when I

Anyway, I switched tanks and the problem seemed to go away. I'm not sure the problem is gone, I didn't push it too hard..I sweat in my seat to get home about 20 miles to go..

I didn't have a problem the rest of the way home, even on surface streets but, again, I didn't try to push too hard.

I,m going to take the truck out after work and try it but, I won't have the load on it. So, my question is if the engine doen't skip without a load do you think fuel filter on that tank could be the problem?

I'm thinking the fuel filter

Had the same problem. Was rust in gas tank which plugged filter in external electric gas pump. Check for filters and replace or clean them. Found filter in bottom of fuel pump which was plugged. also put extra filter ahead of fuel pump. solved problem.
