Question about Ford F-150

1 Answer

I have had my 04 f150 since new and over the last couple months I have experienced a strange problem . For some reason when I have tried to start the motor the darn thing appears to be gas starved . Kinda like running out of gas . The first time it happened I was parked on a downhill slope and was low on fuel . I cranked and cranked util the battery died . I then got a gallon of gas figuring that was the problem . I got a couple more cranks out of it and still same result . I had to have it towed home . When I got it home I figured I would try to start it again just for the heck of it and it fired right up . Go figure ! Now a couple months later I had the same kind of thing happen again . This time I had a 1/2 tank of gas and was on flat ground . I cranked and cranked with no luck . I waited a while , ate my lunch and went out to try again . This time I rocked the truck back and for a bit figuring what could it hurt . Tried again and it fired right up . What gives ? I am totally baffled as to what the problem is . Also when running there are no performance issues . Any help would be great . Thanks ,

When you first start your car, the pump should power up immediately, increasing pressure.

If you add gas directly to the throttle body and the engine starts for a few seconds and dies, then it probably a fuel pump or relay problem.

Intermittent problems are harder to diagnose than full blown problems.

Rocking the car could have rocked the gasoline causing a marginal fuel pump to in the sending unit area of the tank to work again.

Kind of like hitting an old tv and making it work.

Wish you luck on this repair.

The throttle body should be cleaned. There are sensitive wires in there that can be damaged if the proper spray cleaner is not used. Have a diagnostic test done on it to pinpoint the defective parts.

Ford f150 1988 4.9 cranks but doesnt start

If you are getting fuel and spark, than it probably is either a bad ground, or the TPS sensor itself.
