I have a 2004 Chevy Avalanche 1500(4X4) with approximately 86,000 miles. Recently, I have been having problems starting it. About every five starts, the engine will crank but it takes a while to start or sometimes will not start at all. The times that it did not start, I stopped cranking, tried to start it again, and it then started right up. Once it is running, everything is okay. I don't knowif this is an ignition issue, spark issue or fuel issue. I am a novice at diagnosing problems and would appreciate any suggestions.[/align]
Thanks for your help.[/align]
