Question about 1999 Jeep Grand Cherokee
I am working on a 2001 jeep grand cherokee with a 4.7 liter. The engine will not start, I know that the cam position sensor is not showing up on the pcm datta. I have tested the sensor and wiring to the pcm and its working. When the engine is cranking votage is fluctuating between 1 and 5 volts. I have no power to the injectors or the coils. The ASD relay is not sending power out because the pcm is not sending a ground signal to it. I have replaced the pcm and cam sensor and the signal wire. The skim key and vin have been programed in to the second used pcm. Still have the exact same problem, any suggestions??

I would suggest you take your vehicle to an experienced Chrysler technician for diagnosis.
HERE is a description of an ASD setup that may help.

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
