Question about 2002 GMC Sierra 1500
I believe you are telling me that it takes 15 seconds to start the engine. Can you hear the fuel pump kicking? It may be requiring a new relay but I would start with getting the fuel pressure tested cold and see how long it takes to build pressure. Let me know what you find and I will be happy to help.
