I’m working on a 2004 Cavilier with a 2.2 Ecotec. I have no codes, 45psi of fuel pressure, compression is 120,110,130 and 90. The chain didn’t snap and the gears aren’t stripped on the cam gears. I have injector pulse, but the spark doesn’t look like it’s hot enough. I swapped out the control module and coil packs with another car I have. Still no start after all this. I’m thinking it could be the crank sensor, but I have no codes. Anyone come across this before?

Its common in the ion’s to have a problem with the ignition switch. The ignition switch was used in a bunch of cars, I’m not sure if cavalier has the same one.

It will display a lock icon on the dash, and the car won’t start or crank at all.

a quick and easy way to check if its the crank sensor is sit in the car and turn it over, if the tach doesnt bounce up, sensors toast

take a cup of gas and put it on the throttle body and let some into the manifold, try and start the car, if it starts = bad fuel pump

edit: didnt see the 45psi of pressure, try it anyways

Is the theft light doing anything? Almost sounds like a passlock problem. Got a 2nd key you can try?
