Question about 1996 Jeep Grand Cherokee

2 Answers

1996 jeep cherokee limited. Turned it off, next morning it wouldn't start. Took to a garage, and the computer wouldnt allow them to get in. Not firing, no fueling. Am I looking at having to buy a new computer? Is this a relay? I don't want to spend alot more money on it.

More computers are replaced every day than are necessary. That said, they can fail.
Your shop needs to do testing beginning at the harness connections on the computer. pins need to be tested to make sure that there is both power and ground present at the appropriate pins. All fuses need to be tested as well as the ignition switch and connections under the power distribution center. Generally, relays are controlled by the computer, not the other way around. Grounding is important....there are two major ground points and about four more smaller ones that all need to be clean and secure.
The computer itself is very accessible and takes ten minutes to replace. there are many available in wrecks. As they do not have a high failure rate, it's a good bet that one you get that way is good, providing that during the accident, the electrical system was not compromised causing shorting. (best units come from vehicles that had mechanical problems)
If you are dealing with a good reliable shop, they will know what to do.

    I took it to a jeep dealer, and they found it was the cam sensor needing to be replaced.

  • Richard Scordino Jun 04, 2010

    A bad cam sensor will not prevent the computer from communicating with the scanner. Your original problem coupled with the problem the first shop had (having no communication) are more consistent with a "no bus" condition. Your original problem though, without the other shop involved, is also consistent with either a cam or crank sensor failure. (very common)
    "No bus" can be elusive as it can come and go, usually caused by anything from a bad ignition switch, poor connection in the harness, or even a broken contact inside the computer.
    In all my posts, I always stress the importance of testing before buying parts. I hope the dealers solution is correct and that your Jeep continues running well!!!
    Good luck!!

1996 jeep larado driving me crazy

Cars are like that. I think they like driving people crazy. I\'ve been driven crazy by my Sentra for three months now.
Has the fuel pressure been checked? I wonder if your fuel pressure regulator has failed (the diaphragm inside will rupture and suck extra gas in through the vacuum hose attached to the regulator-could be the cause of backfiring). Something to check, anyway.

2000 grand jeep cherokee limited 4.7 liter, v8, at first wouldn't start rplaced battery because dead and then replaced starter. ran ok for a couple days. last night started it and hard time with it...

Pop into to your local garage and have a diagnostic test carried out.
Listen to the advise given. It may save you lots of money, especially if you start the "guessing" game.
It does sound like a part may be blocked or failed though, but the sytem needs to be tested thoroughly first.
Good luck

Heater doesn,t work. Controls on dash sometimes light up & sometimes doesn,t. All of my fuses are good. It seems to act up mostly in the morning. Sometimes if I turn my head lights on my gauges quit...

Morning Charlie,

If it were me, I would check the wires coming & going to & from engine. Maybe something is crossed. That's what it sounds like, anyways.
