As much as I hate having my first post be a tech post, I'm in a predicament and need some outside help, so thanks to everyone in advance.
1999 cherokee sport, 4.0, 4x4, not sure about tranny or axles.
My jeep turns over but doesn't fire. Realized that the fuel pump didn't energize when the key was turned to the on position. Checked relay, continuity is good. Jumped the 30 and 87 on the plug, pump energizes. Gauges were working, checked fuses, and other relays, good. Then the gauges stopped working. Unplugged CPS, turned key to on, gauges didn't move, plugged CPS back in, still no fire, gauges haven't moved. Held odometer button in for 30 sec, turned key to acc, released button, nothing. All relays and fuses are good, haven't checked the board they plug into for shorts, voltage and the like. Where should I go from here. I haven't checked for spark, but if fuel pump isn't energizing then spark doesn't matter, but I will do so this afternoon. Any advice is appreciated.
