    the ignition coil driver is in the pcm (gry/wht wire), you also have your 12v reference off of the alternator (drk grn/blk wire) that particular circuit is protected by the automatic shut down relay. I would check that circuit back up to the relay.

We have a 1995 Jeep Grand Cherokee,ran good then quit,has 8 volts to the coil,the coil isn't firing.Has new parts inside the distributor,new coil,a computer off another Jeep Grand Cherokee,has the same...


If there is only 8 volts to the coil, that is your problem. There should be battery voltage (12.2) volts to the coil with the ignition switch turned on. Connect a voltmeter between the DARK GREEN/BLACK wire at the ignition coil and the POSITIVE battery post. Turn the key on. If the volt meter reads more than 0.3 volts then you have a voltage-drop (high resistance) problem on your coil B+ circuit. The coil is powered by the Auto Shutdown (ASD) relay - this is the MOST LIKELY source of high resistance in this circuit.

95 jeep grand cherokee died wont start,it cranks, checked fuel pump replaced filter cleaned injecters still nothing


Check to see if getting fire from coil or plugs. If not, your problem is most likely the Crankshaft Position Sensor.

$18 - $21 dollars. CPS is on left side of where transmission buckles to fly wheel, near top edge. One bolt and plugs in. (2 wires in plug)

Drive shaft to 4-wheel gear box might be in your way. No prob. 4 small bols and lower front end of drive shaft.

About a 45 - 60 minute job for shadetree mechanics, like myself, and 2 coffee breaks.

Prior syptoms of sensor going bad is engine rumbling real bad when coming to a stop, and sometimes dies but will start.

Hope this it.

CANT FIND CRANK SENSOR


The sensor is mounted in a fixed position in the engine block. The tip of the sensor protrudes into the crankcase at a distance of 0.05 plus or minus 0.02 inch from the crankshaft.

My 1996 jeep cherokee sports is turning over but not starting. No voltage to input side of coil. ASD relay seems fine, crankshaft position sensor??


The CPS is one of the first places to start, but remember that the signal goes thru the ECM first, which ultimately supplies power to the coil, I've had to replace the ECM on my 96 Grand Cherokee 4.0 3 times. The dealer wanted to replace the crack and cam sensors, but it was only the computer that was bad.  Sorry I cant give you any definitive answers but I did get it to turn over when I hit the computer with a wrench!
