weird problem w/ 99 windstar 3.8

[94xlt4.0]

i have a 99 windstar 3.8l that for some reason has an intermittent starting problem. it has problems starting pretty often and i know its not the battery starter or alternator cuz those have been tested and confimred good. i get in and turn the key and when it gets to the accessory position the fuel pump doesn't "prime" and the van wont start. at first all i had to do was open then close the door and arm the factory alarm. then disarm it and open the door then it would start w/ no problem. now even that doesnt work then just by turning the key forward then backwards then forwards anywhere from 10-50 it will sometimes start. does anyone have any experience with this or have any idea what it could be?

See if the Check Engine Light comes on with the key to Run, before or after cranking.
Check the integrity of the PCM Relay if the CEL isn't on, along with the PCM Power Diode. If all that checks good, I'd replace the Fuel Pump Relay and cross my fingers.

I'm guessing that opening/closing the door was just a thud, making the FP relay decide to work, like tapping on it.

If you have a meter, you could check for 12 volts at the Inertia Switch when the FP won't run. If power's there (@ both wires with it connected), it might be new fuel pump time. That power will only be there for 2 sec after turning the key to Run.
