also i think the pcm is getting power since all the sensors ( maf, coilpack, injectors ) have power.

i just tested the harness going into the ICM............ coil a,b,c, to ICM all have power, also the ground in the ICM is good when i try to turn the engine over that ground gets grounded ( before it actually had power ) . But the crank position sensor doesn't get power at all, i know the ICM must give it power, so i'm thinking if the PCM is grounding the ICM , than the ICM is simply not doing its job by giving power to the Crank position sensor and getting a signal back. do you think this is my problem ? the icm ?

Test/ replace the oil pressure sender. If it fails or detects low pressure, it will prevent the engine from starting by shutting off fuel delivery. This wonderful little sender has so foiled me in the past on other vehicles.

I expect that's a possibility. Maybe the starter solenoid is sticking. Are you using the starter from the Aerostar or the Explorer (if there's even a difference between the two)? Perhaps in wiring some of these grounds, you've accidentally provided an extra ground for the starter solenoid or something.

the truck is finally running , it was actually a ground under the fuse box , its a plug i removed the other end that plugs in accidentally thinking that it was for something else . I had to replace the power steering pump and alternator , but the engine is running perfect ( aside from the tranny fluid leaking everyware gota change those lines ) but the 4x4 doesn't seem to want to turn on , i'ma have to work on that later.

thanks so much to everyone that helped , you guys are great
