I own a 1995 JGC, auto, 4WD,4.0L, it has 246000 miles and we have replaced the fuel pump 4 times in 12 yrs, on the last 2 occasions we only replaced the pump not the entire module thingy. anyway having said that I think my problem could be different this time. I had parked the Jeep overnight and the next day it would turn over but not fire I can hear the pump come on for 1-2 sec when the ignition is turned on, also I know that the fuel is getting to the fuel rail, I am somewhat confused ( not to hard) as I also disconnected the fuel line at the inline filter (mounted just forward of the fuel tank) and when I turned on the ignition the pump only ran for the 1-2 seconds despite the fact it could not build pressure in the system, is this ok or is the pump faulty once again. I would like to know if I am getting a spark at the plugs but am not to shure how to do this on my own without meters etc. Sorry to sound like such an fool as I`m a 62 yr old male, anyway thanks in advance, Michael in Northern AZ.

I have a 2001 JGC 4.7L, when coming to a stop at a red light or anytime I am just idling in drive, the oil pressure drops to 0 and the check gauges light dings on. Once I start gaining RPM's the oil pressure shoots back up to where it should be, and the check gauges light goes out. I have recently had the oil changed and it is still doing the same thing. Anyone who has any suggestions on what is going on or how to stop this from happening, would be greatly appreciated.

I just bought a 1996 JGC Laredo 4.0 AT 2WD at a garage sale, Real cheap! I removed the engine and had it rebuilt due to some head damage and piston damage. The machine shop recovered the "missing bolt" the previous owner mentioned when I bought this nightmare. Anyway, after I re-installed the new engine, it started and ran like a champ. However, it won't idle properly. It will rev between 1200 and 600 about six or seven times then die. I used the manual to check all the components: TPS, CKP, MAP, air idle control valve, replaced the camshaft position sensor. I even replaced the PCM with a reman. one, yet it does the same exact thing. All of a sudden my real cheap JEEP is a total burn!! Please someone help!!

I have a 1998 Jeep Grand Cherokee with the 6 cyl 4WD. It has 147,000 mile. Radiator was replaced at approx. 110,000 miles. No other replacements have been made to the cooling system. It has always run with the temp gage just at the "Half way" mark on the temp gage. Lately when I am stopped at a traffic light, or just idling, the temp gage slowly creeps up. It has gotten close to the red mark on the gage, but never hit it. When I start driving again and the air is flowing thru the radiator, it cools back down. Any suggestions to keep it from heating when Idling???
