silverado starting problems by jeof

I have an 04 Silverado 2500HD that intermittently fails to start. On the first try it will crank without starting, on the next several tries it won't crank. The lights light up, radio, etc, just no cranking. After a few tries it may crank and start or crank and not start. At first this only lasted 5 or ten minutes then it would start and I would be on my way. Now I have to let it sit for a couple hours. The only other thing I notice (when it doesnt start) is that when you turn the key on, the fuel gauge shows E. When you turn the key on AND it shows the correct fuel level, you can be sure it will start. Any ideas or solutions would be appreciated. Dealer doesn't seem to be able to find any thing and it doesn't do it ALL the time, just when you are in a hurry!! Thanks

Sounds like a bad throttle position sensor. Course this is just a guess based on what you stated. As far as the relationship between the gas gauge reading empty and the truck not starting is something I've never seen or heard of. Coincidence? Maybe.

I have a 2009 2500HD Silverado with similar problems not only will mine run rough for the first few minutes but the limited slip will go in and out, the traction control flashes trouble and makes the traction lock up and then the ABS lights up and locks on the brakes. Now they have it in service and cannot find any problems. Any ideas other than taking it back or crushing it?

1996 Chevy z71 will turn over but not start by olblue20

My truck will turn over fine but wont start. most of the time when i turn my key on my gauges dont kick on. every once in a while they will though, usually when i turn the key very slow. i replaced the fuel filter and fuel pump thinking it was a fuel issue. also switched out what was believed to be the ignition module under the hood on a bracket near the distributor. could this be the ignition itself on the steering column?

forgot to mention that i have gotten it to start once or twice usually when the gauges will actually kick on, but if i turn the truck off and try to start it again it just continues to turn over.

Hey obyone, Where is the throttle position sensor located? I know...I should subscribe to Chiltons or that Alldata place...but you're cheaper

TPS is located on the throttle body.

95 C1500 start problem by jhl385

I only get a click at the starter when trying to start my truck. This started with a bad battery, but I replaced it with a new one yesterday converting it to a top post. The starter is a rebuilt one replaced this spring and I pulled it today and had it checked - it's fine. So I though maybe the cable from the battery to the starter is bad and I used jumper cables to go from the neg. post on the starter to the battery and left the OE cable in place. Same thing happened, hit the ign. start position and only a click at the starter. I even "borrowed" another starter from the parts store and it did exactly the same thing.
Any ideas what I can check now?
Thanks.

i have a 2000 3/4 silverado 6.0. when i i crank the engine it struggles to start. sometimes it starts on the first engine rotation but most of the time it takes about 6 seconds to start, or starts on the second crank. once running the first 5 seconds it nearly dies, and then brings itself back alive. also while in idle or redlights there is a slight miss. have an obd2 and it shows no codes. has new battery, plugs, wires, fuel filter. altenator tests fine, fuel pressure is good. fuel pump tests fine. any help would be appreciated
