1994 Jeep Grand Cherokee - Page 2 - Answered Questions & Fixed issues

Have you checked it for engine codes? Trouble codes should point you in the right direction.

possible tps issue.

Change the temperature sending unit/temp sensor. When starting, the sensor will tell the computer to put the engine in cold start mode to give a bit more fuel and raise the idle a little so it WILL start and keep running without ever touching the throttle. Once warm-up is completed, this sensor will tell the computer to stop the cold start mode and go to normal run mode. THAT is your only problem.

hi there. check this link out might show you. Where is the heater water control valve on 94 Grand Cherokee Limited...

It could, in fact, be an intermittent open at the solenoid. Make certain all the cables are connected properly and are appropriately tightened.

I'd start with a new flasher relay (they're cheap). If not that, then go to those lamp sockets and check for corrosion. I had issues similar w my 95 laredo...it was the flasher.

make sure you dont a separated belt on one of your front tires

Hi, Suggest you buy tin of spray oil named WD40 spray liberally over engine & electrics this should solve all your problems. I know this is not found in any book etc but assure you I know by experience. Please give feedback at [email protected] Thanks, Malcolm Campbell.

Sounds like the ecu on your jeep is not powering up all the relays properly, allowing spark. Have the ecu checked to see if the capacitors, which regulate power to the main relays, are dead and need to be replaced.

Chang filter and basket, then have a trany flush dun at a shop

The clicking sound is an indication that the battery is almost dead, and will not activate the starter any more. When is the last time the vehicle was tuned up and serviced? How many miles do you have on it? You can't drive it forever and expect that it's going to always start and run properly. You need to have it checked out by a qualified mechanic - the symptoms you have sketched out here could be almost anything. Do yourself a favor and invest a few dollars to get some reliability back in your vehicle, or maybe find out that it's going to cost a lot of money to keep it going. Then you can make an informed decision on what to do next.

The click...click sound is telling you the battery is close to dead or the wires are corroded on the posts. I would put a new battery in and see if that solves your problem or go to a store like Auto-Zone and have them check out your battery and alternator. They also can read your on-board computer which may point you to something else that has failed.

If it's been sitting a while it's always a good idea to put some sort of gas treatment in it. Ethanol added to gas nowadays is bad about getting water in it if it sets.

starter cannot act good if it does not spin the engine over quickly with new battery pull it for a bench test under load check and clean terminals and check for good ground point

smoke from the dip stick hole is not an indication of a sensor problem more like running engine with out any oil in the sump

I'm pretty sure there is no TCM on a '94 model-that came in later years. It wouldn't hurt to do the filter and fluid change, but if fluid is clean, it might not help.

run the fault codes could be the reverse servo/solenoid or the TCM problem When you have such a problem , the person you should be taking it to ia an accredited automatic service center, get a proper diagnosis and a quote It is electrical , and besides those mentioned coulkd be harness wires and connections

The power booster maybe bad or the master cyl maybe going out. I would have someone check them out.
