94 Aerostar starting problem

I have a 94 Aerostar that won't start. I have fuel pressure and spark. No faults on ECM. Any ideas. Bebobullet

Check that the air cleaner isn't plugged and the intake is clear. Use a noid light and check for power to the injectors. Check the compression in the cylinders. Check the fuel pressure in the system.
You may have jumped time.
These are some tools needed.

I had the same problem.
It turned out to be a "dead spot" on ther starter motor.
My tow truck operator just banged on the side of the starter with a large wrench (to jar it off the dead spot) and it started. I replaced the starter quickly after that.
