Yesterday ,filled with despair I posted that my 2001 Cherokee sport would not run. It would crank,but not fire. No fuel pressure, no codes (reader didn't see the computer) ,dash gauges dead at run, and the odometer read no buS . I don't know how to check for spark on these rail systems ,so couldn't do that(I have the Haynes manual . The procedure described seems to involve all sort of complication and parts I do not have. Any help in this regard would be great.) As it turns out those issues are the result of a dead PCM . Any pointers on changing it ? I have a rebuilt on the way from Auto Computer Exchange. Tanks a lot for the help. I will let you all know what happens next.

 

Just wondering how the "auto computer exchange" place was? Did it fix your problem? Mine is on it's way out, I just ordered a replacement ECM from them.

Thanks,
J
