Hello all,
So I have a 2002 Liberty 2wd 3.7 Automatic.
I've been having issues with a no crank condition when the jeep is hot. It could be from driving or from the ambient temp in the air, when it gets warm enough it doesn't crank. It won't even try to turn over. Apparently I'm not the only one who has experienced this from what I've seen online. There seems to be a variety of causes.
When I first got it, after not being able to find a solution I ran a fused, push button start to the starter. That worked great. when it didn't want to crank, I turned the key and hit the button and it started. Now that doesn't work.
I had a code for the Neutral Safety Switch so I replaced the Solenoid Pack in the transmission. That cleared the code but it is still not cranking when hot, although it did seem to help briefly. No more codes are showing.
The starter solenoid is getting 12v.
I think I may have narrowed down a clue. The Starter Relay 15A fuse when cold shows around 11v. When the vehicle is hot and won't start, it's only reading .35 (it varies).
Could this be caused by a bad starter switch or possibly a frayed or loose wire coming from the ignition switch?
I appreciate any advice!
