1996 Jeep Grand Cherokee: Engine will not start?

The System turns over all electronics work but engine will not get started.


The most probable reason is a Crankshaft Position Sensor.

The Working of CKP is as follows:----
The CKP sensor sends pulses to the engine computer that in turn controls the ignition coil.
If the CKP does not send pulses or they are wrong, the engine won't start.

Another possibility to check is as follows:----
Check if you have a spark. If there is no spark, then it is good idea to scan your Jeep for trouble codes as the CKP sensor usually sets a code.
If you have spark, then the problem could be with the fuel supply ( fuel pump or its control including wiring).

This details will help.
Thanks.

Car not starting?

There are few possibilities that can cause this problem.
check your fuel pump, mass air flow sensor, crankshaft sensor, spark plugs, spray starter fluid in your air intake and try starting your car if your car starts then shuts off then your fuel pump is bad if it doesnt start up at all then that means your fuel pump is good and something else is wrong with your car. Fuel pump are some of the mian causes of a car not starting but remember only do this if the car is cranking and not starting if your car is not even trying to start then its your starter.

Car will not start?

In this case Car started fine before pump started draining battery.


You could now have a driver authorization problem. 
1. Plug your central locking pump back in.
2. Make sure that your remote batteries are good. 
3. Lock and unlock the car with the remote. 
4. Try to start car.
5. If no start you may have to synchronize the anti-theft system.
6. Point remote at the interior rear view mirror, press button on remote twice and turn ignition key key on within 30 seconds.
7. Turn key off and then back on and try to start car.
If car starts, you will need to find out why the pump won't shut off. 
You may be able to unplug the pump after you are able to start the car.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.
