1996 grand cherokee 4.0 engine ,Coil wont fire..

hey wayne i read thought some other forums about the code that was given, a couple of the forums said to disconect the battery to reset the computer and get everything synchronized and another said to remove the ckp or the cmp and re-install, in you case the crankshaft sensor. so i hope that this helps a little, but i would try to un-install and re-install the crankshaft sensor sense it sounds like it was installed improperly.
 
Thanks for the info.I did disconnect the battery cable first thing when the engine started for the first time to reset the computer.That didn't help.The crank sensor had a metal bracket that the first person working on it left off.After doing some research,I found that the bracket was needed for the bolt to go through making the ground.A second person removed the crank sensor bolt and installed the bolt through the bracket then through the sensor into the bell housing .The sensor and bracket looks like it will only go one way.Very hard to install.Located in a hard place to get to.If after checking the cam sensor,plug,wireing harness,etc and it still runs bad,I will get the crank sensor removed and reinstalled.Thanks for the help...
 
Back probing connectors--special order "back probe" needles from Fluke, or straighten one leg of a small paper clip, hit the edges of the straightened end with a file or stone to "break" the edge--don't sharpen it--then slip that leg into the back side of the connector and hook your meter to it.
