If you are posting a follow-up to a question you started days or weeks ago, follow the link in the automated e-mail you got when a reply was posted. That will take you to the original question where you can continue the conversation and all the previous posts are listed. Some of us have been known to spend months with one person to find a solution, and we need to look back at times to see something you posted previously.
I am not a GM expert, but I can suggest that if your engine runs for a few seconds, the crankshaft position sensor and the camshaft position sensor are working. Stalling after a couple of seconds is a common problem on GM vehicles caused by the anti-theft systems. They are quite effective at keeping owners out of their cars. We have a few experts here who are much better qualified to work with you, so consider reposting your question so they will see it.
We need to know the engine size when looking up wiring diagrams and parts lists. Those can be very different between two optional engines. We look at the mileage when making judgments as to the best suspects. Thank you for including those. I wish everyone would.
