GMC Troubleshooting Questions? Ask a Mechanic for Answers
Welcome, I'm Chris (aka Moose).
Not many techs online today and we are busy busy. Sorry for the long delay. I believe I can help on this concern if you still want or need help?
Were the plugs changed for maintenance or were they done trying to address the crank no start issue?
Any trouble codes stored?
Have you, can you, do you know how, or do you need help confirming if your getting ignition spark, injector pulse, and fuel pressure?
Great, so you are getting spark and injector pulse meaning there is no fuel pressure or a compression issue. Will it start briefly using starting fluid?
Hello again Chris here,
I am contacting you because the post has not been closed or rated. We have 7 days to get a post rated before it times out. When a post times out, that means its no longer on my active list (if you reply I never know it.) You have already paid the fees to get this question answered, but it appears you're not pleased, or need more help.
Let me help some more. Is there anything else you feel I could offer so you would be pleased with my help. I have the option to call you if that would be better.
