GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hi. After reviewing the timing document you provided, my husband informed me that he did this 2x just as shown on the diagram. Question you asked me is the fuel pressure at fuel rail has 45 lbs psi. Is it possible that a camshaft celinoid could be sticking thus making seem out of time? Also are there any camshaft sensors that could affect this as well? This is turning out to be a real headscratcher!
Checking on that now. Oh my. Hope it is the crankshaft sensor!
HI, Tim. Security light does go out after a few seconds. Just replaced the crankshaft sensor and it won't start. It tries but won't.
HI, Tim. Have you found anyone yet?
Have not heard from anyone since our last contact at 1:34 est yesterday. Is no one available to help?
