GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hello and welcome! My name is ***** ***** I can assist you with your question! Can I start by getting your VIN? Thank you!
Thank you! I will do some digging tonight for you when I get home.
Hello and sorry for the delay! I do apologies as I cound not find the link to this question. Anyway, we are addressing the no start condition? Have you checked the inputs to the fuel pump relay while cranking? There should be two powers and one ground. One power comes from the ECM B fuse and the other comes from the vehicle control module or computer. Can you tell me which one your missing?
