Auto made loud noises and stopped running. would not start. Had towed to Jeep dealer who had it for three months and they made sure that the timing was fine. Replaced cam and crank sensor. still wouldn't start. they finally called us to have the vehicle towed back to our home because the manufacturer told them it was probably the TIPM and wiring harness. the cost for the part and to install it (with no guarantee it would fix the car) was $2,300 which we don't have so we have a vehicle that we can't even start.
