Does your battery go dead?

Sounds like it has jumped timing, dont know which engine you have so could be chain or belt.

Hmm, been a while since I played with one of them, but I do recall a simular problem. Try this,,, locate your ECM that you replaced,find the orange wire, and trace it back. I have found breaks in this wire in different places, mostly in the harness running under the rad support. The orange wire is a power wire for the ECM.

turning the key without starting it untill you hear the fuel pump stop (it will make a humming noize this is the fuel pump pressurizing the lines) then immeadiatly after it goes off turn your key to the off position repeat this 3 times then your car should start

Check cam/crank position sensors
