I have a 92' XJ w/ a 4.0 and auto. If I unplug my TPS and my Map sensor it will start and rev and I can drive it around the field but if I go out on the road it is kind of doggy. So far I have replaced the ECM, Crank Sensor, Map Sensor, Throttle postition sensor, and IAC. This all started the last time I took it wheeling, I was halfway up a ledge and it just died like I had shut the key off. I figured it was just a crank sensor so I replaced it and it didn't do anything, so then I put a TPS in it because mine was getting kind of rough looking after 236,000 miles still no start. So one day I started unplugging things to see if I could get it to start and if I unplugged the TPS it would kind of start and if unplugged the map sensor it would set there and run, does anyone have any ideas what would make it die when I plugged these two in? My fuel pressure is good all of my sensors ohm good, have the right voltage inputs and outputs and they are getting the correct voltages to the computer.
