Tahoe won't start

With key on? Constant power? Look under box for green crusties or a broken wire on that fuse

We can crank it from the ignition switch but when he plugged the ignition switch back in the key will not crank it. All lights work inside and out, dinging noise when key is in ignition and everything just won't crank.

Did you ever find out the problem? My Vehicle doing the same thing.

Anyone got answers for this problem?? Mine is also doing the same thing.

Do a voltage drop test on battery cables. Test the ignition switch.

Wire integrity from ignition switch to fuse box?

Check all your grounds, body, engine.

Crankshaft position sensor. I'm going threw the same thing. Right after I replaced that it started doing it again. This time I believe it's the starter. I turned it over many times before I replaced the CPK. Good luck

I have the same question won't start must jump will run after once turned off won't turn on again must jump
