02 F150 Fx4 Lariat, 5.4L. Had to let it set for about 2 months, had to take battery out and charge it. Now it won't crank, will turn over and act as though it's going to start at first but then nothing but turning over. have checked all fuses and are good. Any help please. Thanks

Check the fuel shut off switch. Passenger side footwell.

Are you sure it has fuel in it? It sounds like a stupid question, but we have a 01 supercrew that sat for a year and wouldn't start for that exact same reason. Honestly, I remember it having an 1/8 tank when it was parked. We even put stabil in it lol.

After a day or so of thinking we'd have to replace a clogged fuel pump or at least a filter, we added a few gallons. 3-4 cranks later it fired right up.

Only 2 months? Shouldn't be a problem at all really

So it does crank, just won't fire.

How many times have you attempted this, how many cool down cycles ? What I'm getting at, if the injectors lost prime for some reason (shouldn't have in only 2 months), it can a couple attempts to fire. First attempt, you can try like hell to get it to go and she just won't fire. Next day she fires up first crank.

Keep in mind, - If you crank the engine more than 4 seconds consecutively, the PCM shuts down the rail...so it aint going to start. Stop, , attempt again before 4 seconds are up.

If all the posts above don't help, begin troubleshooting...FUEL first.

Hopeful it's not mice!

Thanks for the replies. Been working a lot and attending classes for work. I will be able to work on it this weekend. It does want to start at first but will not and then just continues to turn over. yes, it has fuel in it.

thanks for the help. The fuel shut off is ok, was not activated and fuel is getting to the fuel rail.

Can you hear the fuel pump when you urn the key on? Does the theft light flash when you turn the key on?

Cant check the fuel pump as I'm by myself or at least I cant hear it, I'll get a friend over later this week. As for the Theft light, does not flash but does come on and then goes out with the other lights that go out after a few seconds.

It's a pretty noticeable noise you should be able to hear with the key turned and the door open and ear out. It's almost like a little "thud" that's what you should be listing for, I don't crack my truck until I know the FP has primed, just easier on it.
