Vehicle description: 1997 Jeep Grand Cherokee Laredo with 160,000 miles on it. This has been a great vehicle for me with minimal repairs. Engine: straight-line 6-cylinder displacement 4.0 liters, 185 horse.
Problem: Won't start
Symptoms: Engine cranks but does not fire. I do not hear my fuel pump turn on when I turn the key to run (as I usually do) nor do any of my gauges move when I turn key to run. I do not have spark.
What I have Tried: Removed every fuse/relay and cleaned pins on the fuses and re-inserted. I'm hooking it up to a code reader tonight and see if any codes come up. I will re-post, however would like any insight or thoughts. Sounds like it may be the on-board computer? Strange though, no gauges, no fuel pump, & no spark. Three different systems (unless there is one connection that interlinks them to the ignition system). Voltage off the battery is fine, headlights, horn, dome lights, door ajar are all fine. Engine cranks over strong. Battery good. Removed cap and cleaned all connections and checked for cracks. Everything looked good there, although that wouldn't explain the fuel pump and gauge problem. Used the vehicle with no problems in the AM and went to start it a few hours later (engine was still warm) and nothing.
Thanks in advance for any advise you may be able to offer.
