Question about 2003 Jeep Grand Cherokee

2 Answers

2003 Grand Jeep Cherokee will not start.

2003 Grand Jeep Cherokee started fine, shut it off, then did not have enough power to start, then we hooked up battery cables and tried, failed. Tried another 4 times, each time the engine turned over less and less, finally did not even click, totally dead. The battery tests good CCA and no bad cells.

Could be a faulty starter or bad connection between the battery and starter. You could use a meter to check for voltage at the starter but it will not show resistance in the cables.

This procedure usually works:
·Check the battery cable connections:
Make sure the positive cable, makes a good connection at the battery and at the starter. Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine.

·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.

·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's pinion gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck pinion gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.

If none of the other solutions work it can be the crank sensor which is about $30-$60 bucks and is very simple to replace. Good Luck

Do you have an alarm on this? If you do, that is most likely the problem. There seems to be a problem with the alarms. You may want to have a new key made just in case. Sometimes the keys are magnetically charged and after time, it wears off.

If your Jeep ran hot enough to shut itself down then you likely have at least a blown head gasket for starters. The casue of the overheating also needs to be addressed. Timing gears won't make an engine overheat nor will they cause an engine to lose compression.

If there is not enough compression to let it start, then you need to take it to a shop and have it checked out but you are probably looking at a head gasket and probably a warped or cracked head. Hope this helps.

Jeep starts and shuts off before even moving


You need to check the Diagnostic Trouble Codes and see what comes up. It definitely appears the ASD (Auto Shut Down) is kicking in, which is there to protect specific engine components.
