You also might want to check the fuel relay, see if it's been burnt out.

If the truck is still having issues, you might wish to look at the TPS (throttle position sensor). If it's sitting at too low of a position (broken spring usually), it could be killing the truck.

SOURCE: 2004 f350 6.0 diesel.Engine surges

Hi, i want you to clean the air intake valve and idle speed control valve, follow the procedure below.

Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

1999 rv with ford v10. Starts good, idles good, runs good FOR 5 MILES..then if it idles , it dies...still seems to run ok as long as the rpm is over 1000 (IDLE). Ford shop says needs new fuel pump.


Did Ford tell you the pressure of fuel was LOW? They should know what they're doing.
Does it have an idle air control valve (IACV) ? Have you cleaned the MAF sensor? don-ohio (:^)

6.8 V10 hard to start and backfires once I got it to start fuel pressure was 87psi at idle no codes im suspecting fuel pressure regulator?? Any ideas?


If its the fuel system it should not backfire. It could be out of time synchronous (ignition - crank sensor - belt). becareful!!! you could hurt it if you try to start it to many times.

E350 v10 econoline


You did not say what year the truck chassis is, so I will give a generic answer.
If the throttle position sensor was at fault, the computer should set a trouble code. So if there are no codes, I would question the fuel pressure or venting in the tank. Fuel pressure could drop off to just enough to keep the engine running but not have enough to rev up. Or the pressure vent valve in the tank may not be working and the tank could be building up a vac. Its also possible the fuel filter is clogged up enough to restrict fuel pressure or volume.
You would need to check base fuel pressure and the condition of the gas tank when the problem occurs which could be tough to do on the road. You could take the gas cap off and see if it will rev up to check the venting. That will probably turn the check engine light on due to the tank being open with the engine running.

Ok you have no pressure from fuel pump to the injectors and you replaced the pump. Sounds as if you need to check or replace the relays which send the signal from your ignition switch to your fuel pump to engage/shutoff. Warm weather area sorry doesn't really apply unless you're in an older carburated vehicle
