starts, then stalls

Hi,
My 2001, 5.4L V8, expedition has done the following twice. When hot, I turn off the truck, come back minutes later, the truck will crank. It starts and it idles horribly rough then stalls. The second time, it wouldn't start, just cranked. Leave it for 30 minutes and it starts and runs like normal. The rest of the time it starts and runs normally.

64k mi, new plugs and COP's. New Idle control valve, recent transmission service.

Of the candidate problems (no fuel, no spark, no air), what's the likely cause? Inertia switch, Ignition control module, MAF sensor?

Thanks,
jeff

Cam or Crank Position sensor? Kind of a guess - need to get the codes pulled to give direction to test further.

The computer on this truck is less than helpful. I've got no CE light. Will there be codes to pull (at a shop), with no CE light?

Thanks.

In some cases yes. Not severe enough to pop on the light, most autostores can pull the codes for free.

Me too!

I have the same problem in my 2000 4.6 expy. It only happens when its hot out side. The last time I had to wait 2 hours before the truck would start up normal. I was told to replace my MAF. We shall see.

I tried to pull codes, but it was clear (I expected this since there was no CE light).

The truck's not done it again. It might have been from running my gas tank *very* low and stirring up some junk. We shall see.

Best,
jeff

I had the exact same problem when I ran the gas low on a long "in the sticks" drive. I had to fill up at some off the wall station and it took two tanks before she ran properly.

Good Luck
