Having problems with your 1999 GMC Sierra ?
My 1999 GMC Sierra wont start. It has the 5.3l V8
\015 It turns over just fine and it sounds like it just fires right up when you turn the key but it immediately dies. I've replaced the fuel filter, spark plugs, wires, fuel pressure regulator, and it has gas. It has about sixty pounds of pressure at the fuel rails. There is spark at the plugs. It seems like it wants to run but just wont. We can get it to run while spraying starter fluid into it but it sounds really crappy.\015
Sounds like a security problem that is preventing starting. It will run for a few seconds and then die.
