Changed the after market fuel pump 2x and now are trying a Chrysler pump. Changed a few sensors and checked the injectors. The symptoms all point to the fuel pump check valve so we will know later.
Also the mileage according to the display is all over the place but not where it should be. The guys at the shop have been good with all of this and are not charging me for the extra time involved.

the coolant tempature sensor will do this. it cost about $20.00 and takes 2minutes to put on. It tells the computer how much fuel to give the engine based on temp.

Put in a Chrysler fuel pump and it is working fine. I will remember the coolant sensor for the future but that did not come up as a problem on the computer

Feb 15, 2012 (11:11 am)
My cherokee will not start. Ran fine one day, drove it home, parked it, would not start the next morning. So far, I have replaced the coil, the bell housing sensor and the plastic plate below the distributor. Still I have no spark coming from the distributor. It turns over fine, just never starts. I don't know what else would be involved with sending a spark, except the computer. Any help will be greatly appreciated.

Computer may have lost it's ground. If you GC has factory alarm the ASD will be 'rattleing' for lack of sufficent ground. Under Alternator, attached to block is the primary ground to ECM. It's 2 lg. gauge wires/cables attached to brass like square. Remove, clean plate and block attachment point (threaded stud)with wire brush thoroughly and replace using die-electric grease.
