Ok the transmission and engine are back in the car (94 from my sig) and I am using a 95 6 speed harness and what I believe to be either a 94 ecu or a 95 (I have two). The car cranks over just fine but there is no fuel and there isnt spark. Thought maybe it was VATS but the security light comes on when you turn the key but it stays solid and then turns off a couple seconds after that. The fuel pump will prime if you connect a wire to the lead by the ecu and it will build and hold around 45psi no problem. Checked all the wiring and can only find two grounds that aren't connected. One is a small one coming from the harness that runs right under the ABS block and goes up in front of the radiator. The other is a strap that I am told runs from the coil ground to a 10mm bolt on the frame by the ABS block.

The ICM checks out fine (Advanced Auto checked it 5 times and it passed all 5 times). We did a test using Shoebox's website where we used a volt meter on the ICM with the key on but didn't get anything there. We're not sure where to go from here?

Please some one help me so I can get this out of the garage.

 

No ideas at all?

 

????????

94 from your signature????? What signature?????

95 Harness from a 6 speed What did the car have originally???

94 or 95 ECM???

No wonder no one wants to answer. Make your problem so we don't have to pry information from you.

Bypass the VATs function with the proper value resistor and eliminate it as the cause of the problem.

Start with the basics. Check for spark at a plug. Then go to the coil. Then check the coil for power then for IC signal.

Then move to the fuel side. Look for pressure using the key not the fuel pump prime connector. Then look for injector pulses.
