Stalling problem 2001 TJ

[Len Mongeau]

My 2001 TJ has had a stalling problem for a year now.
Starts,runs, stalls then cannot get it to fire.
Engine turns over fine but will not start for several hours or a day.
Changed TPS, dealer ran diagnostics. Seemed to run OK in winter time.
Just failed again this summer. Replaced fuel pump & filter. Cleaned fuel rail and replaced 4 injectors.
Failed again,had it towed. Garage says replace computer now.
Got a $1000.00 into one issue and still not resolved.
P.S. No error codes at all.
Can anyone help ???

Thanks
Lenny

Have someone spray a small amount of starting fluid into the air intake while you are cranking it over. If it runs on starting fluid the problem is fuel related. If it doesn’t run then your problem is most likely ignition related.

Yes, the issue now is ignition as the fuel system has been replaced,pump, filter & injectors.
No failure codes on PCM and passes dealer test. Problem is intermittent and shows up
in warm humid weather. Jeep runs fine in the winter.
Very frustrating, no confidence in the darn thing after one year of ownership.
I was reluctant to buy a Chrysler product and now I know why.
