My daughter's 95 cherokee died suddenly last night on the expressway
. Here's what I know. Keep in mind, I have about an hour's drive to get to the car, and want to fix it myself.
She was traveling at about 70mph on the expressway, the engine chugged shifted gears a bit and then quit. She coasted to the side of the road, and I picked her up in the darkness and didnt have time to diagnose or check much. Here's what I know:
1. New alternator within 6 months
2. Battery is strong - lights all work well
3. Engine cranks, but does not fire
4. Her ammeter went to 9 just as this happened
My guess is that it is a coil pack, but am looking for input from others. I've verified the battery is good. Can the coil going out kill the motor like that? I realize it could be a fuel pump, but why would the ammeter go down if that were the case? Any ideas?
I plan to check the coil first, and have been told if it has a yellow spark it is weak, and no spark... well it's done. Could it be a crank sensor if the coil is good? If I have spark, and still no fire, I would assume either the CS or a fuel pump?
Help, please, and thanks in advance for any responses.
