2009 C30 Multiple Inject Circuit/Open and Misfire codes

Post by movingim77 » Sun Nov 12, 2017 5:19 pm

Hello:

Looking at possible purchase of 2009 C30 with 123k, with potential engine problems. The current owner brought it in for evaluation and her car repair facility said "No compression on Cyl#5, 90% Leakage through exhaust". I went over to inspect car and it runs like one cylinder is not firing, ran scanner and codes were the following; P0201 through P0205 "Injector Circuit/Open" and P0301 through P0305 ""Misfire Detected". If the engine had a burnt or stuck exhaust valve thus causing loss of compression on Cyl #5 why all fuel injector circuit/open and misfire codes for all cylinders?

Thanks
Jeff

Got me thinking, I suspect codes are from when the tech performed compression check and had disconnected the leads to injectors and coil packs......
