    TIMING LIGHTS
    There are two basic kinds of timing lights — DC powered timing lights, which operate from your vehicle's battery, and AC powered timing lights, which operate on 110 volt house current. Of the two, the DC light is preferable because it produces more light to see the timing marks in bright daylight.
    Regardless of what kind is used, the light normally connects in series with the No. 1 spark plug using an adapter. Models that are more expensive sometimes use an inductive pickup, which simply clamps around the plug wire and senses firing impulses. Inexpensive models use alligator clips; one clamps onto the connection between the plug and the plug wire, and the others clamp onto the vehicle battery terminals.
    NOTE: Some timing lights will not work on electronic ignition systems, so unless you still own a vehicle equipped with points, check to make sure the timing light you buy will work.
    The biggest problem you will probably have when using a timing light is trying to see the timing marks on the crankshaft pulley. Before you time the engine, mark the appropriate timing indicators with fluorescent paint or chalk. Stay out of direct sunlight when you time the engine and buy a timing light with a xenon light, not a neon light. Timing lights that use a xenon tube provide a much brighter flash than those that use a neon tube do.





    Fig. 1: A modern electronic timing light. Note the inductive pick-up clamp.

Check engine light still on after changing crank and cam sensors


You may need to reset the codes. Replacing the sensors may have fixed the problem but the codes will still come up until you tell the ECU that you have. An auto electrician has the correct tool to remedy this.

Replaced cps,distributer(cap,rotor,cam position sensor)checked coil good still no spark,replaced coil wire and plugs is the computer next?ignition control module is in the pcm i think


If the check engine light does NOT come on when cranking at the times when it won't start, then your ECU is in need of repair. The engine will only start after the check engine light comes on and the ecu is what controls that. It's likely going bad, causing the delayed start problem typical of early 90's jeeps. Repair or replacement services for your jeep ECU are available on ebay.

1996 Jeep Grand Cherokee No Start


I would be thinking that there is a good chance that you need to be checking out replacing the computer, if you aren't getting any communication with the proper scan tool then the computer isn't communicating with anything in the vehicle...... I would have guessed first off that the ignition control module might be bad but that is obviously part of the computer also, I would be looking in that direction.

Run the car with the radiator cap off. Make sure the radiator is topped off with coolant or water will do just fine. While the car is running look in the radiator neck and check if there are bubbles coming out.
Maybe bad head gasket.
