GMC Terrain
Hello,
I have a 2012 GMC Terrain 3.0 litre with 230,000 km AWD. Its been running fine, then my wife parked in front of the driveway. I rolled it back (in neutral without starting the engine) just past the driveway. The next day it refused to start and still will not start. I had a mechanic come out and do a diagnosis. He said it had power, spark, fuel pressure, fuses were good but compression was low ( he checked the front bank of cylinders .. 90-60-90 psi). He didn't do anything else.
The starter is turning, engine just won't fire.
Is the low compression the reason it doesn't start, as he said? Am I looking at engine replacement or a valve and head repair/replacement?
Thanks
