Replace the gas tank mounted fuel pump - AND the filter and gas guage sensor. $300-440 at a dealer.
Get them to clean out the water and "gel" (its parrafin I think) from the tank. Insist they do it.

Whats wrng with my 97 jeep grand cherokee it died and wnt start bak up it turns over but acts like not getting gas. I sprayed starter fluid and it started a sec thn died.


It is not getting gas. Could be bad fuel pump,and most are now in the fuel tank.If it is the fuel pump and it is in the tank,this can be a fairly major expense.($400-$500)This is not an unusual problem,and many auto repair shops can do it.

My 2002 grand cherekee check gauge lights keeps coming on and the oil gauge would drop when I slow down or is at a stop. Please advise


This could be a faulty oil pump. or more commonly a bad oil pressure sensor you can call. If its the pump i recomend you have it fixed as soon as possible. The check gauges lights up because the oil pressure isnt as much as required. But common problem is the sensor replace the sensor and the engine oil along with a filter hope this solves your problem.

Like many others, I'm having trouble with my '97 Jeep Grand Cherokee with the 4.0 L engine and 4X4. Engine sporadically misfires, especially when coming to a stop. Sometimes dies on idle or startup....


Make sure the ignition coil drive is in proper sync. The sync should be at or close to 0. Also try an engine decarb this works great on 4.0 engines. Also if the misfire is coming for #3 there is a bulliten on installing a heat sheild around the #3 injector because it takeing a lot of heat from the exhaust mainfold that sits right under it.

97 Jeep grand cherokee 6 cyl. idles down to 0 and dies.


any leaks in intake or exhaust upstream of the sensors, sparkplug condition and engine controls/sensors for out of range operation (including fuel pressure and condition of regulator)
IAC should be cleaned and checked as this can cause poor idle and shut down. I'm not saying not to change O2 sensors, but unless everything else if OK, it probably won't help.

1999 jeep c. 4.0 litre engine. Fuel drips from muffler wont start


How is this car running? Remove the vacuum line from the pressure regulator on the fuel rail and check to see if there is any gas coming out of the line. If you see gas then the regulator is bad.
