Hi, sorry to hear you are having issue's. these jeep's are great but have been known to have electrical issue's. I had the same problem with mine. Now i alway's turn the key just far enough to turn on all the electronic's and listen for the fuel pump to run and stop then it crank's on the third revolution of the engine every time. the fuel will ease back to the point where there's no fuel or not enough to have the pressure it need's to start and if you let the fuel pump build the fuel pressure back up that may fix it. try it and see if that's the issue.
#914 of 1241 Key light & haywire gauages
Nov 27, 2011 (2:19 pm)
Have a 2000 GC Laredo - first started showing key symbol then gauges going haywire - runs just fine. Found loose positive battery connection which seemed to resolve the gauge issue but key light remained on intermittently. On for a few seconds -off a few seconds. Dealer did not seem to have a clue - no codes found - at least they did not charge me.
Today I tried disconnecting the battery completely and let sit for about an hour - hopefully to let computer reset. So far no key light and everthing works - crossing my fingers!!!

what I did on my 2000 4.0 gcl, was to start unpluging all the 3 wire sensors on the engine (crankshaft position, camshaft position, map sensor, etc.). If any one of these sensors has shorted out, it will kill all the gauges. As I have found out since working on mine, the most likely culprit is the crankshaft position sensor. As soon as you unplug the bad sensor, the gauges will come back to life and more than likely you will hear the fuel pump relay in the fuse box in the engine compartment energize. I learned that a bad sensor will not kill the gauges, only a shorted out sensor.

i have a 2000 gc v8 4x4
well the dealer seems to have fixed my guages going on and off. skim light coming on and car dying.... always started back up but when the temp outside went below 50 degrees the skim light would come on and the guages would start and stop working. they ended up replacing the instument cluster, the pcm, the crankshaft position sensor and maybe the skim module as well..... when they put it back together they left the skim module disconnected, their idea and i was all for it...... $1600 but they seemed to get it right
#920 of 1241 1995 Jeep Grand Cherokee cold start problems
Dec 04, 2011 (10:24 am)
I've scoured the boards but never found a solution to this, so here goes:
I have a formerly well behaved '95 JGC Orvis, 5.2L (remember when we called one of these a "318"?), 165k miles, which, rightly or wrongly, I love.
It has developed problems, which may or may not be related.
First, It has the relays clicking (repeated clicks, from the ASD and starter relays) before the CEL comes on, then requires multiple tries before it will actually start, but when it finally starts, it runs fine. If it stays warm, it starts more easily for the rest of the day, if it cools all the way down, it goes through the relay clicking --> CEL light up --> start process again...
Second, it has a draw that takes the battery from fully charged to barely charged overnight that has thus far eluded testing to identify the cause.
Finally, while driving over longer distances it has begun tossing a code 032 (EGR) which goes away on it's own, and the VIC has started complaining about Servicing the 4WD Switch. I have had it on an OBD scan tool and all of the numbers are in a range that seems ok once the thing is running and warmed up...
I have pulled all of the fuses and relays, tested them, and cleaned all of the contacts. I have replaced the CPS, ASD and Starter relays, the battery and the ECM, none of which have solved the problems.
Has anyone seen any of these issues / problems and found a fix that didn't involve a shotgun and a shallow grave?
#922 of 1241 93 Jeep Grand Cherokee Starting problem. Inline 6 engine. Need help, Please
Dec 05, 2011 (11:29 am)
So I went to go start my jeep and turned the keep on and didnt hear my fuel pump coming on, like I usually do, and it wont start. So I went and bought a new fuel pump and new fuel filter and installed. Now when I turned my key to the on position, I hear a ticking noise coming from under the hood from the fuse box, where the relays are. So I went and bought a new fuel pump relay switch and installed. Turned key on and ticking noise coming from the Auto Shutdown relay switch so I switched that relay out and still makes a clicking noise for about 30 seconds. Even when I remove the relay switch from the box it still clicks for a bit then stops and still wont start, and also noticed that my rpm gauge is bouncing from 1 to 1 1/2 Rpms for about a minute then stops. If I spray starter fluid into the throttle body it will try to start but wont. Never had a issue with this jeep til I changed the fuel pump Yesterday. Please help, idk what else to do. Thank you
