cranks over no start 99 f-150

i get spark but no trigger signal to injectors will run on starting fluid. any ideas. need help.need more info? thanks.

Does it have an emergency fuel shutoff switch? My Escort had one and acted exactly the same. It activates in an accident, but mine tripped just sitting there.

Fuel Cutoff Switch Ok Thanks Any More Ideas

On a friends gm when the throttle is to the floor it signals the pcm to initiate a clear flood mode. His throttle wasn't to the floor but the throttle position sensor thought it was.
Good luck and let us know.

you need to check your fule pressure. Check that and report back.

Both the spark and the injectors are ECM controlled, so any sensor that would take out one, will also take out the other.

Do you hear the fuel pump running for a short time after you switch the ignition on? If not, you have a fuel problem. First check for power to the fuel pump, if you have it, replace the pump.

I have 40lb fuel pressure at the rail. when i crank the engine over the theft lite keeps flashing on the dash will that kill injectors?? I think its suppose to stop?? I just put in a rebuilt pcm.Are the keys coded into the pcm?? thanks for the help.

Yup, the PATS "key" programmed into the new EEC is different than the PATS "key" in the PATS module and your ignition key. someone screwed up big time.

PATS = Passive Anti Theft System.

Thanks for all the help guys over and out.
