    Check your spark plugs and wires - both at plug and distributor. And your distributor.

Do you get no spark in just one plug or in all of them? If you are getting spark in some plugs but not others, you likely have a cracked distributor cap, burned electrodes in the cap or bad wires. If none of the wires are getting spark it _may_ still be the cap if the center electrode is melted. Check the cap and if it appears to be good you can check for spark from the coil. Be CAREFUL though when doing this. For a very low price you can get an ignition spark tester from your local auto parts store. In the US they run between 8.99 and 15.99. Simply find a ground which is away from the coil and connect the ground clip to it. Then disconnect the coil wire from your distributor cap, but leave it connected to the coil. The end of the tester is like a spark plug tip. Snap it into the coil wire firmly and turn your vehicle over while watching the tester for a spark. If you get spark from your coil, but not through the cap to the wires, you will likely need to replace the cap and rotor even if they seem to be good. If this still does not solve the problem, your distributor itself may be done for. Just remember to use caution when testing as the coil does produce enough amperage to give you a nasty shock, especially in wet or damp conditions. Follow instructions on the packaging of the tester and you should do well.

You say you changed the cam sensor. A1391 code is a crank sensor on the top of the trans. bell housing.

yah direct ignition coil pack does away for the need a a distributer cap and rotor.much higher energy ignition system where the computer tell when to fire.if that helps.not hard to change.as long as you change them one at a time so you don't screw up the order.

1995 Jeep Grand Cherokee Sport it just won't start. It cranks, that's it. It was running fine yesterday.


If it was running yesterday and only cranks this morning you need to determine which you are missing - spark or fuel. The spark is easy - pull a plug and let it spark to the frame. while cranking. If you have spark then you have to start checking the fuel system.

1996 jeep grand cherokee 5.2L v8 is cranking but wont start doesnt look like its getting a spark


Might be your jeep's ecu is bad. Does the check engine light come on your dash, when you turn the ignition key to on, before cranking? If not, the ecu is bad. If the check engine light does come on, it may be the crank sensor is bad on your jeep.

Have your crank sensor checked. It won't send a signal to fire the coil if the crank sensor is bad.

Cam sensor, crank sensor, bad coil, all could give no spark. Check all fuses and relays.... wiring connections as well. 320 is a crank sensor code.

Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)

I have 1996 jeep grand cherokee limited. its not starting.


Does it crank? IF it does check to see if you have spark at the plugs. If you don't have spark then the problem could be a crank sensor.
