My 2000 Jeep Grand Cherokee was doing the exact same thing. The dealership told me the crank sensor had shorted out and caused all of the problems. They replaced it and I am back in business!!! I agree, mine was giving "NO BUS" error on the odometer and the CPS (Crank Position Sensor) was the culprit. Located on the rear of the top lip of the transmission, above the opening for the flywheel. I replaced mine myself, HUGE PAIN....so, I'd recommend having it done...
When you open the hood does the underhood light come on ? If not , it sounds like you have a dead battery or a poor cable connection to the battery
Check the battery.
You have a ground problem,take it to a good auto electric guy.
Dead battery? Maybe if it makes clicking noise -dead battery
This is often from a dead battery.
from a dead battery to working battery
First of all is the lights working in the car? (over head lights or any kind of lights) If your not getting anything at all (no lights) then you should check the battery. If the lights are working then I would check your starter. Most of the time if you take the battery somewhere to get checked they will do it for free. So I would start there. Did you try to get a jump to see if that would start it? Hope this helped some.
starter, solonoid, ignition, battery. if it clicks when you turn the key then the battery is really dead or its the starter the battery could still be jumped if its the battery.
The battery is under the front passenger seat. You hook jumper cables to the jump start posts under the hood. You will find a red cable and a grounding stud near it to attach to.
You pulled something loose somewhere when you where working on the vehicle or ran the battery down with the doors open and dome lights on all day.
Sounds like a low battery.
its your fuel pump
