I replaced the crank sensor, cam sensor, tested the coil (in specs), the asd relay is good, getting power to engage the asd but no voltage for the circuit it makes. Cleaned ecm ground and checked all applicable fuses.
I jumped the asd and introduced 12volt to the circuit, nothing.
I jumped 12v to the green coil wire, nothing.
I eliminated the aftermarket alarm, nothing.
I checked for burnt or broken O2 wires, nothing.
So in conclusion there is no voltage passing through the asd circuit, there is no voltage at the coil or injectors, not even for a second. I followed the test procedures I've found on here and other sites. It all seems to point in one direction.
Am I missing something? Or am I correct in assuming the Ecm is toast even though there's no codes and the dash powers up.
Thanks for any input.
have the same problem?
