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.

To confirm the problem, the basic troubleshooting is required.

Temperature too high on Truck?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.


If your truck's temperature is too high, it mean the truck is overheating.

when the truck's temperature becomes too high, is there still water in the radiator? 

If there is water in the radiator and the car overheats, then it means there might be some dirt or blockage in the radiator or condenser. 

When the car is on the motion, air passes through the front and assists the fan to cool the engine. There are situation whereby air doesn't have free flow because of blockage in the radiator and condenser. Dust and debris can cause blockage. If this be the case, have your radiator washed thoroughly and cleaned. 

If there is no water in the radiator when the car overheats, then there is a probably a leakage from the water pump. Or maybe your fan isn't blowing properly. The fan might be blowing weak air. 

The above are what could cause your engine to over heat. 

So start the check from the radiator. Poor water into the radiator, wait for some minutes, look under the car and observe if water is going to leak. If there is a leak, it might be from the water pump or a leaking hose. 

If water from radiator has no leak, have your radiator washed and clean the condenser has they might block air that is suppose to cool the engine. 

Also, make sure your fan is blowing properly or well enough to cool the engine. 

Make sure you have the above checked thoroughly as they are the major causes of problems like this. 

This overheating problem could lead to a burnt gasket and this can dry the engine oil which will eventually knock the engine. So have this problem fixed to prevent further damage that will cost you more money. 

Lastly, remove the hose that connects the radiator to the engine, water from the engine will come out. Pour water into the radiator, the water will flow through the hose down to the ground. Do this severally. Now connect the hose back to the engine, pour water into the radiator. Start the engine, the water in the radiator will reduce, add more water till radiator is full.

In summary, the major cause of over heating problem is from the radiator, fan, water pump, blockage in the hose, and dirt in in/on the condenser. These are area you need to concentrate on.

How to replace Thermostat on Acura Car models?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

The procedure is as follows :---------

Thermostat

REMOVAL & INSTALLATION

1. Disconnect the negative battery cable.
2. Drain the cooling system into a suitable container.
3. Locate the thermostat housing by following the upper radiator hose to the engine.
4. Loosen the hose clamps then carefully detach the hose from the fitting.

If the hose is stuck, carefully use a pick to break the seal between the radiator hose and the housing. If the hose is deteriorated, replace it with a new one.

5. Disconnect any sensors or switches that may interfere with the removal of the thermostat from the housing.

See Figures 1, 2 and 3

Fig. Fig. 1: Remove the thermostat housing bolts

Fig. Fig. 2: Pull the water outlet neck away from the housing

Fig. Fig. 3: Note the installed position of the thermostat, then remove it

6. Unfasten the retainers, then remove the thermostat housing.

Some coolant may leak out of the housing as the seal is broken.

7. Remove the thermostat carefully noting how it's installed.
8. Clean the mating surfaces of the thermostat housing.

Many thermostat housing's are made out of aluminum alloy. A plastic scraper is very effective and will not harm such metals.

To install:

See Figures 4 and 5

Fig. Fig. 4: A new gasket must be installed before installation

Fig. Fig. 5: Install the thermostat with the air bleed valve at the top

9. Install the new thermostat and gasket.

Install the thermostat with the jiggle pin facing up. This acts as an air bleed and must be at the top of the thermostat to operate properly.

10. Install the thermostat housing, then tighten the bolts securely.
11. Connect the radiator hose and tighten the hose clamps securely.
12. Install any remaining components, then refill the cooling system.
13. Start and run the engine until it reaches normal operating temperature while checking for leaks.

This details will help you.Thanks.
