01 Tahoe, won't start won't crank

[SLCHOE]

I have a 2001 Tahoe and have another problem to add to the ever growing list of issues and quirks.

Truck has ran and started fine since I first got it. Today I turned the truck off to go in the house. Came back out and went to start it; nothing. No cranking, no clicking, no nothing. Battery has a good charge, alternator is basically new. All the dash lights come on, everything works. Just won't start.

Any idea where to begin troubleshooting this issue?

Check the IGN A fuse in the under-hood fuse/relay box. Should be a 40 amp fuse.
Also check the "CRANK" fuse under the driver's dash area. Should be a 10 amp fuse.

If that checks out ok, look for 12V on pin 85 of the starter relay (under the hood in the fuse.relay box) when the key is in the "crank" position. If you don't have 12V there in crank, then I'd look at the ignition switch or wiring.

Applying a jumper wire between battery positive and pin 87 will crank the starter motor.

Just curious, you said, "has a good charge." Have you tried jumping it? Pretty common that you can have enough to turn all the lights on but not enough to turn the engine over. How was a good charge determined?

If you are getting a "click" then your getting power to the starter...

Id double check
*battery state
*battery connections
*battery connections
*battery connections
*Like said before, see if you have power on the signal (smaller) wire when the key is in the crank position
*There is always the super scientific method of smacking the starter with a hammer...
