Question about 1994 Jeep Grand Cherokee

94 Jeep Grand Cherokee check engine light and display panel

It's a V8 and had been driving fine until the other day when the "Check Engine" light came on.  then i noticed the following 3 things:
1.) the display panel went blank and then came back on flashing with the wrong date and time, etc. like an alarm clock after the power has gone out.
2.) the needle on the battery gauge was in the red while idled at a stop light.  it came down a little while in motion, but back in the red at the next light.
3.) the "ABS" light next to the "Check Engine" light came on.
somebody told me it may be something called the "Oxygen Sensor."  could this be?  thanks in advance

Did u try to find out what error code u have? if not turn the key over 3 times not full just to get a current flowing, on the third turn over leave it turned over and your engine light should flash twice a few seconds after the other. that lets u know that ur into the computer and now it will flash a certain amount of times depending on the code just keep count on how many times it does and look the code up in the manuel. it may get u closer to a solution

My 93 jeep grand cherokee is not getting fuel...if I disconnect the negative post for awhile and then reconnect it, the jeep gets fuel and will run....what is going on?


If the check engine light does not light up on the dash when you turn on the ignition, at those times when your jeep doesn't want to start, then your main jeep ecm is in need of repair. The fuel pump relay will get energized only after that check engine light comes on. It's a known problem, especially with the first and second year production Grand Cherokees, 93 and 94.

Look to see if the check engine light come on, on your dashboard, when you turn the ignition on. If that light does not come on, then your ecu computer is in need of repair and your jeep will not start until that light does come on.
Alternately, if that light is on, it could be your crank sensor that's bad on the jeep.
