[FIXED] 2006 Malibu 2.2 - No Start after engine replacement
2006 Chevy Malibu 2.2. Replaced engine due to mechanical issue. The car ran with no problems when we pulled it into the garage. (Aside from the horrible noises from the valve train.) Replaced the engine with a junk yard motor from Saturn ION. This was the third engine in this car. The second motor was from a Cavalier. No idea what happened to the original, but the Cavalier motor ran several years with no problems until recently.
With the new engine, the car cranks but won't start. (It started once, and ran very badly for a few seconds, and never again.) There is no spark (need to recheck that), and no injection. 60 psi on the fuel rail. The scanner shows 190 RPM when cranking, so I believe the crank sensor is working. There is no cam sensor.
The ground connection for the ignition module (G106) was mistakenly connected to the battery terminal on the starter. It's now corrected, but it is possible some damage was done. I realized that when I was checking spark, I didn't have the opposite plug wire grounded, so I need to recheck that, but definitely no injection. The immobilizer light comes on for a few seconds and the goes out-I think that is correct.
There is power to the ignition module and to the pink wire on the injectors.
We have limited test equipment. A DMM, test light, and fairly basic code reader, but it does provide live data. There are no codes now, but an evap code showed up once, but never reappeared after clearing it.
Can I assume the crank sensor is working since I have an RPM indication? What else can cause a no spark/no injector pulse on this car?
You had the answer and I didn't get it at first. I thought you meant PCM when you said module. I didn't realize that the ignition module had anything to do with the fuel injectors.
But that was it. New ignition module and we're good to go.
