weird starting problems

2000 gjc won't start for several minutes if you let off the key too quickly. It use to be 10-20 minutes and its taking longer and longer to start. Same problem also happens if you have your foot on the accelerator even a tiny bit. Never use to do this. Anybody have any ideas what it could be? Does some computer or something have to re-set if you screw it up? Thanks in advance for any ideas!

There's another post here with similar problem, I think it was the Crank Position Sensor.

hmm. I'll look into that. When we used a different key it seemed to be just fine. So maybe something is wrong with the key?

If you have a alarm system on it it could be the key , since it doesn't do it with other key Dale

check the key the WJ use a sentry key system (that needs to be programed or need to be matched up to the sentry system to work properly)

check with the dealer.
