Distributor cap wiring diagram

depends on the year and model. for example, on my 97 Grand Cherokee Laredo 4.0L , the cam sensor ( also called pick up relay or coil ) is underneath the distributor cap and rotor. flat, round, plastic device with a magnet and little wire (2) with plastic connector. the crank sensor is on the top left ( driver side ) , backside of the bell housing of the transmission. easy to find if looking up at transmission from underneath jeep. wire harness runs by it. will need a couple of long handled extension bars to remove bolt holding it in. do not forget to put little gold bracket back on with new part. this acts as a spacer as well as for support. you can look up more specific info for your vehicle on e-how.com. just type in for example : signs of a bad cam sensor on what year vehicle, how to change the part on vehicle etc.

could be a number of things. could be as simple as a clogged fuel filter, plugs and wires maybe

Do you have fuel pressure at intake?Have you scaned for codes? Is there any spark at distributor cap?

You didn't post your engine size so please choose the apprpriate diagram:





1989-98 2.5L Engine firing order: 1-3-4-2 Distributor rotation: Clockwise






2.8L Engine firing order: 1-2-3-4-5-6 Distributor rotation: Clockwise





4.0L Engine firing order: 1-5-3-6-2-4 Distributor rotation: Clockwise





5.2L and 5.9L Engine firing order: 1-8-4-3-6-5-7-2 Distributor rotation: Clockwise

CHECK ASD RELAY THAT IS AUTOMATIC SHUTDOWN RELAY IN THE POWER DISTRIBUTION CENTER UNDER THE HOOD IN ENGINE COMPARTMENT.IF ASD RELAY GOOD PROBLEM COULD BE CAMSHAFT SENSOR IN THE DISTRIBUTOR.TO SAVE TIME AND MONEY HAVE JEEP SCANNED FOR CAMSHAFT SENSOR AND CRANKSHAFT SENSOR FAULTS.

Review the Jeep ZJ Repair Manual in the Firing Order (page 10 and 11) for 4.0L 6-cyl and 5.2L 8-cyl.

I really hope hepled with this (remember rated this help) Good luck.

check the cam sensor and crank sensor, also is the distributor turning,possible distributor gear pin broke

1-5-3-6-2-4
ALL Jeep 4.0 motors use this firing order. Any year, any model, high output or not.

Also, the spark plug wire placement on the cap, in a clockwise direction from the post nearest the engine block is: 6-2-4-1-5-3.(to the left side of the number 6 post, there should be a hold downscrew or strap for fastening the distributor cap to the distributor.

Does the vehicle crank for extended period of time upon first starting? If so the fuel pump needs replacing.
