I have a 2002 Silverado Z71 4x4 with about 78,000 miles. I love my truck but it has been a pain for a couple months. A couple months ago it started having issues starting. It turns over and cranks fine. However, the first time I turn the key it cranks but will not start, soI let it crank for a second or two and then hit the ignition again and it fires right up. Also, if I turn the key to on and let it sit for about 5 seconds it usually starts right up. Once it is running it runs and idles fine.

I have tried a couple simple items like changing the fuel filter and running an injector cleaner through, still the same. I do not smell fuel or see it on the ground or engine. Someone even suggested it may be a fuel rail or an injector that is stuck open and bleeding the system pressure off into the engine. Not sure what is going on but seems like maybe it is the fuel pump, but I am wanting it not to be because it looks expensive to have it doneor difficult if I do it myself, since the fuel tank has to be dropped.

Anyway, has anyone else had the same problem? If so, what was it? Or, what other items should I check/try before going the fuel pump route?

Thanks,

Troy
