jsmoe Posted January 12, 2008 Share Posted January 12, 2008 I have an '89 comanche eliminator 2wd 4.0 that started to not start occationally, no spark. Then it finally quit altogether. Well I have tested some things and replaced a few things. I have replaced the coil, distributer(used), CPS (new) and the fuel pump balast (it was cracked). in that order. It did get spark to the plugs after the CPS change and it will start and idle smooth but when trying to rev it a little to pull out it backfires and has no power. I'm stumped :( any ideas out there would be appreciated. Dave aka jsmoe Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted January 12, 2008 Share Posted January 12, 2008 Double check the WIRES for the CPS. The plug was a known problem. try a meter to be sure the plug is good. If found to be faulty, just hard wire and eliminate the plug. One other thing to remember, just cause a part is new, dosent eliminate it from speculation.

LEAD_NOT_FOLLOW Posted January 12, 2008 Share Posted January 12, 2008 TPS ? Throttle Position Sensor. Located on the throttle body. See above link on how to test it. Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted January 12, 2008 Share Posted January 12, 2008 Throttle Position Sensor Its on your throttle body. don't JUST REMOVE IT!!! The way its attached is a specfic setting for your trucks idle. (if its a renix ) CW Link to comment Share on other sites More sharing options...
