The old one allows it to crank but the new one when installed will not allow it to crank. That’s where I’m stumped. I think the old one works intermittently I think. That’s what in trying to figure out.The Jeep will run for approximately 30 to 40 minutes and shut down and will not start until it cools down and then it will crank and run fine. I acquired a new one just to troubleshoot the Jeep. But it will not even start up with new one.
