1994 Ford Aerostar 6 cyl Two Wheel Drive Automatic 225000 miles

new fuel pump (tested old one off the van and it works but not on the vehicle) not pumping - changed fuel relay switch, been hard to start as if it wasn't getting any gas - would run fine then during damp part of the time not start or very hard to start - sprayed wire dryer and it helped part of the time, spayed starting fluid and it worked part of the time - now no fire - starter will turn over but engine will not start as if there is no gas but the tank is full (fuel pump not pumping) checked the inertia switch cause it died when hit a bump and has not started since, coil appears to be ok and spark plugs appear ok going to check ECM next - any suggestions?

Have you checked for spark and fuel to the engine? Have you checked the Electronic Engine Control (ECC) relay?

Let me know.
