Having problems with your Jeep Grand Cherokee ?
97 grand cherokee 5.2 no spark no injector pulse. replaced crank sensor but still the same.
Well the crank sensor would have been my first guess also... I have a family member this week go without his vehicle for 3 days, because it wouldnt start, he was using the same key he always used, but would just turn over, no spark, no fuel. i got to reading the manual, and his has an anti theft system in the ignition switch.. somehow it got activated... he said hes not sure how, he just parked it when he got home, and went out to start it, and nothing, just cranking with no starting. anyhow, the key he was using was one he had made off of the original, so i had him go in the house and get me his original, put it in the switch, and the vehicle started right up, the key was chipped with a code, and it was somehow being read by the ignition switch... his is a 94 so i wouldnt put it past them to put it in a 97.. not saying thats your problem, but i hate to see someone put a bunch of money in a vehicle, thats not necessary, he was going to.... needless to say he was glad it was an easy fix, but very frustrated for the 3 days with no vehicle. hope this helps
