Won't Start

Having a problem with my 2002 Avanlanche. Sometimes it won't start. All the lights come on, gauges, radio, but it won't even act like it wants to start. Go out the next day and it starts right up. Any suggestion

Have you checked your crankshaft position sensor? My 2002 AV would do the same thing, changed it a year ago and had no problems since. Here's a thread you may find useful: http://chevyavalanchefanclub.com/cafcna/index.php?topic=4815.0;all

Changing it was pretty rough only because I have big hands/arms. The area is extremely tight, I literally had to have my wife help me tighten the 10mm bolt from underneath.

Good luck!

Do you mean the engine does not crank

Yes. It won't start, nothing. You would think its a dead battery because it won't do anything, except everything comes on. And then go out there later and it starts up.

Start with your battery cables make sure they are clean and tight.

When you say won't start you have to say if it turns over and fails to start
