GMC Yukon will not start	Sign In

I have a 1999 GMC Yukon, in the last two weeks I have gone to start it and it will not start...The engine turns over fine, but will not fire...It acts like it not getting gas...I waited 30 minutes and tried starting it again still would not start..I had it pulled to the GMC dealer the next morning when they went to work on it, it started right up, no codes were available...The security light goes off so I don't think, but it might be, the passlock.

Fuel pump may be going bad, or maybe a loose connection on the cranktrigger sensor. I hope to hear what caused your problem.

Get your fuel filter & pump checked. you may have a fuel line problem. Next time you go to start it, turn the key to ON, but do not crank it, leave it like this for about 1min then try and crank it. Give the fuel system time to prime the engine. Lemme know.
