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 sitting for year,now will not crank and go in gear?

Car starts but will not crank.
If you live in an area that has high humidity, this is a long time to leave an engine with out turning over or running. The cylinder walls will get corroded and rusted. This can freeze the pistons to the cylinder walls. Even in normal weather this can happen. You only option would be to remove the injectors and try to get some penetrating oil into the cylinders to get it to free up and work the crank pulley back and forth to try and free it up put even then it may never start.In that case,getting the complete inspection done at local car garage is advisable.

Car brake light Functions and details?

Automobile brake lights are designed to warn the drivers behind you that your automobile will be slowing down or stopping. Fundamentally cars have brake lights, on rear of the automobile & on the upper level roof line. The third brake light also called Cyclops light is inter-graded for additional safety.

 A brake light electrical technique involves a simple positive & ground technique controlled by a brake light switch.

The brake light electrical circuit is protected by fuse. The brake light switch is connected to the brake pedal. The brake light switch rests in the open position & closed (electrical contacts connected) when the brake pedal is activated. You can fine-tune the brake light switch by moving the main switch housing within the metal bracket. On some automobile models the brake light switches have additional functions like cruise control brake sensor & ignition key interlock function.

The red brake lens can melt/burn when the brake lights are kept on for longer period. This also affects the brake light bulb holder as well. 

The American automobile makers have incorporated the brake light circuit in to the turn signal technique, & vice versa.

The Japanese & European manufacturers design the brake & turn signal electrical systems separately. For this reason troubleshooting the same issue will be slightly different from the different styles of manufacturing.
