Underdog Posted March 1, 2009 Share Posted March 1, 2009 Did you change just the nozzle? Or the electronic unit? If the ECU has been changed, then you need to have the dealer flash the engine computer to "learn" the new injector.

I changed the electronic unit no 2 but it worked 1 day with full power and after that there lack of power Quote Link to comment https://www.bigmacktrucks.com/topic/8477-no-power-mack-truck-model-cx-613-v-mac-iii-system/#findComment-31527 Share on other sites More sharing options...

fjh Posted March 9, 2009 Share Posted March 9, 2009 I would like a little more info!What year is the truck! Is the exhast temp down or up!You may have a failing fuel transfer pump. or bad drain back valve low exhast temp!How many times was the code logged for the failed eup.The other thing is if you changed the pump your self you need to have the eup cal code installed in the ecu for perfect injection control.
