No-crank condition after sitting.

Postby Begle1 » Fri Sep 04, 2009 9:06 pm

After I let my truck sit for longer than a day, it usually won't crank with the key. If I jumper the plug at the battery, it will crank and start just fine.

It has never failed to crank with the key if it has been driven within 24 hours.


How is this possible?

Here is a wiring diagram that may help you troubleshoot.
