2000 Jeep Grand cherokee Laredo wont start. Engine turn over . No noise from fuel pump with ignition on. Replaced fuel pump and filter.Turn ignition on- pump did not run.Jumped the fuel pump at the pump relay.Pump worked and pressurized fuel rail. Still no start. Checked OSD relay and fuel pump relays and fuses-all good. I noticed that the fuel guages were malfunctioning. Battery guage hardly moves.Battery full . The anti theft light stays on as I tried to start engine.
Sounds alot the the pcm it controls the fuel pump and ign system but the anti theft would keep it from starting because the key has a transponder in it programmed for that vehicle and that would kill all ign if triggered ... 2000 Jeep Grand Cherokee

Hi, I have a 1995 Jeep Grand Cherokee 6 cylinder, 2wd. I need to replace the A/C Fan relay switch but I don't know where the relay is. Can anyone help me to locate the relay switch? The issue my Cherokee is having is, when I shut off the engine the fan will not shut off. So the battery will die. Also I can no longer can control the fan-a/c on the console. It just runs loud and blows air out as though the fan is on high.

1993 Jeep Grand Cherokee will start then immediately die. I've replaced the Crankshaft sensor, ignition coil, fuel filter, battery, new plugs and wires, new cap and rotor, tried swapping the fuel pump relay with the auto shutdown relay and installed a new ECU computer. Before installing a new computer the jeep would crank but not start. After installing the new computer the car started right up. I then attached the vacuum hoses to the air cleaner assembly and now it won't keep running. Any ideas

I have a 1995 Jeep Grand Cherokee Limited ,when I go to start it, the relay starts clicking and the fuel pump starts pumping after about 15- 20 minutes of leaving the key on. Also the security light comes on. After the fuelpump pumps up pressure the security light will go out, then when I go to start it the RPM gauge and the injectors go wacky. The RPM gauge continues to jump all over until I turn the key off, at the same time the RPM gauge is going all over the injectors are pumping gas, the en
Certainly sounds like a bad fuel pump regulator. You have a 95 so the regulator isn't part of the fuel pump (on 96 and newer its all one assembly.) You don't have a fuel pressure tester by any chance do you? That would be a great tool in this situati ... 1995 Jeep Grand Cherokee

1995 jeep grand cherokee electrical problem. checked wires to starter. theyre good. the battery is grounded good. have voltage to fuse panel. i was checking continuity by hooking a wire to the negative terminal and checking the switch plug on the back of the heater control panel. had continuity. then i switched to positive terminal. i had continuity. this' to me means there is a short somewhere, but it is affecting the window and lock controls also. is there an easy way to trace a short. thanks,
It depends on how you were checking continuity.\015\012If you are using an ohmmeter (which is only $3 at Harbor Freight), then the question is what resistance reading do you get?\015\012The positive is continuous with the ground, through ... Jeep Grand Cherokee

I have a 94 jeep grand cherokee. i repleced the power steering pump, and the pully with it. afterward the jeep keeps eating belts and over heating. i replaced the thermostat. on the way home it over heated and cut off, but there was no fluid running out. as soon as it cooled some i was able to start it and get on the road. please help!!! I'm wondering if its got anything to do with some kind of relay swicth?
If it keeps eating belts I would look at how the pulley is installed, if it is pushed on too far it will have resistance and be misaligned with the other pulleys thus causing the engine to labour all the time. also have a good look at the rest of the ... 2003 Jeep Grand Cherokee
I have a 1993 Jeep Grand Cherokee Laredo. I love the jeep. I have 380,000 original miles on her and never had any problems. BUT.. When I go to start it now all it does is turn over. Will not start. If I leave the key in the on position for a while ( it varies from a few seconds to a few minutes), I can hear what sounds like a relay click a few times and then the Check Engine light appears and goes away and after the noise... it will start and run like nothing is wrong. Got a new fuel pump ($200.
If the check engine light comes on then there must be a trouble code stored in the PCM memory. What is the code when you turn the key on,off,on ,off... then leave it on....count the engine light blinks. (Don't start the engine during the ... 1993 Jeep Grand Cherokee
