My 1994 Jeep Grand Cherokee won't start in very hot weather. Acts like it has a vapor lock. Starts right up in cold weather but here in Iowa we have been having hot humid weather and it won't start but once I finally get it started it runs fine. What can I do to fix this problem?

My guess is there is ingress, via a leak, of un-metered air after the Mass Air Sensor. The air under the hood can get very hot on a sunny day. If there is a leak in the filtered air ducting or one of the vacuum tubes has become detached from the i ... 1994 Jeep Grand Cherokee

When my 2004 jeep grand cherokee is first started and cold and i drive it for a bit ~ 1 mile or so at a certain higher rpm then slow down it will stall. It takes a few tries to start it up again but then runs good after. There is no engine light on. It happens always when cold. I have tried gas line antifreeze but it seams to be a motor/cpu air/fuel mixture? problem any ideas thanks

Can't give you a definite answer (testing will) but if the temperature sending unit and the manifold air temp sensor are a bit out of range, the information going to the computer may at one point be in conflict resulting in an improper fuel ratio. D ... 2004 Jeep Grand Cherokee

I have a 2002 jeep grand cherokee (2 WD, 4.0L), it seems that when I try to start it (cold or hot) it won't immediatly start, the starter going fine but it seems like no fuel is getting to the injectors, I changed the fuel filter and this worked for a day. However if I pull the relay and depressurize the system it will start immediatly after replacing the relay. The system is pretty clean because when I changed the fuel filter the fuel comming out was clean.

1995 jeep Grand Cherokee Laredo 4.0 6 cyl. It will start up cold. fan works. oil pressure is at around 60 to 70 pounds and fluctuates. The pressure will eventually drop to 40. The real problem is when it gets hot (around 210) it won't start when I turn it off or if it is running it will die almost every time. I let it sit 30-45 min, it starts with a little drag. Can someone help me?

1st 210 is on the really high side, get a lower temp thermostat say 160 degree for it, the reason it dies and wont start is the computer tells its too hot to run safely thereby kills iginition to save you a ton of cash, also check your cooland if its ... 1995 Jeep Grand Cherokee

Why would my 2002 Jeep Grand Cherokee only blow luke-warm to cold air when the fan is on high? First the heat went on the highest setting, so i used the second highest. Then it started to coll as well...now the two highest fan setting will not blow hot air. Also, I don't seem to get a lot of air on my feet, regardless of the setting. I had my heater core done in August of this year. Would this have anything to do with it? Could something be off from when they had the whole dash off? I can't real

Sounds like you need a blower motor resistor located down under dash on pass side next to blower motor. This is a comon problem and I have changed many of them. thats just the fan speed problem. Ive seen the blend doors break easily on those jeeps. t ... 2002 Jeep Grand Cherokee

1996 Jeep Grand Cherokee Laredo 4wd 4.0 I have had to replace the ignition coil 3 times in a little over a week.

1996 Jeep Grand Cherokee v6 dies at stops/red lights and sometimes at speed, also after stoping at the store or somthing it doesnt want to start. It has spark, turns over it just wont fire.

Any chance the check engine light is on ?You are correct in thinking the starting fluid would point to a lack of fuel, but its also possible the engine would start without it once something cools off a bit. Even a wiring harness problem could co ... Cars & Trucks

I have a standard jeep cherokee 1994. 6 cylinder inline engine. the heater will not heat up at times. it all started with the heater being so hot i could smell it melting the blower control switch until it eventually melted the switch. i did not think it was that hot. the switch just hangs down now and the blower blows on 1 mode and that is high. it still was doing fine until it starting to take a long time to heat up and then it started only to heat while i was driving. now it seems to blow col

My 1994 Jeep Grand Cherokee (5.2 liter V8) has a number of symptoms. First off my speedometer quite working in addition to a "Service 4WD switch" alert that occasionally goes off. This has been going on for several months. Then one day it wouldn't start, which after taking it to a mechanic turned out to be the fuel pump. After replacing the fuel pump the Jeep just didn't run well and progressively got worse. Now the jeep has very little power if any at all and occasionally wont start or will die

I would say it is a throttle position sensor.If it is bad,it simply does not know what is going on with the gas required or being used.It also is an input to your computer(ECM or PCM).Your computer then tells the car something isn't right,stop workin ... 1994 Jeep Grand Cherokee

Your ECU is going bad and needs to either be replaced or repaired. That 'no check engine light for 20-30 minutes' is a common problem that tells it's an ECU problem.The ECU won't power the fuel pump and other relays until the check engine light illum ... 1995 Jeep Grand Cherokee
