Me and all my buddies have gone as far as we can with my truck's engine... I need help. Again. Here's wha-happend: It was running like a champ Saturday, it sat all day Sunday, tried to start it today and it turned over but sounded labored like the battery was weak. Tried it again and just got this whirring sound. Charged & cleaned the battery (it was fine). Watched the fan from the cab and it did not spin when I turned it over so I figured the starter wasn't engaging. I set about installing a new one. That made no change other than it looks better than the old one. I forgot about that stupid liquid clutch fan not turning til it's hot. The engine was turning over the whole time but all I heard was the starter. There was none of that "Nuh-nuh-nuh" sound that you normally hear. Just the sound of the starter and the engine doesn't shake at all but it is turning over. Pulled a plug/got spark. Put finger over plug hole/got compression. Watched valvetrain from oil fill hole/valves are moving. Depressurized fuel line, turned engine over agiain/got fuel pressure. Sprayed starter fluid into throttle body while cranking/Nothing.

The only thing I can think of is that the timing chain slipped a cog, the computer is fragged or something has gone wrong with that crankshaft position gizmo but even then it should have hit once or twice, even if it's 180 out. Especially if it's sparking with mouthfull of ether.

Any ideas as to what to try next? It's a 2000 Silverado 2wd.

Thanks,

Sorry, I don't have a code reader nor any way to get the truck to any place that does. Outside of having it towed and I'm trying to avoid that.

You can borrow a scanner from Autozone for free...

I checked w/ every GM tech in Memphis today and the most common answer was to kick the fuel tank. Seriously. Kick the fuel tank.

So I went home and kicked the fuel tank. And my truck started. I give up.

Took it to the 'Zone. No codes found.

Thanks,

get a fuel pump for it before kicking it doesnt work anymore and do the filter too.

CN Spots,
Could be one of two things. 1. Could be the fuel pump inside the tank or 2. Most likely, a bad wire harness that connects to the fuel pump up top the fuel tank to the plug underneath the frame. Just trace the plug in connectors and look for black/brown burned spots. I say this becuase a friend of mine has a 2000 Chevy Venture Van that did this and I though *** was the fuel pump but it did it again and it ended up being the electrical wire harnes plug in that plugged into the bottom of the vehicle and then it goes onto the top of the fuel tank where it plugs in there. That is probably what is going on with yours. :)

A new pump's on my list. Pricy little devil. I'll check the wires first.

Thanks again!
