GrabbinGears705 Posted March 26, 2014 Share Posted March 26, 2014 Have a 99 mack ch 600 and did a PM on it and it was good for a day or so and then we found it had no power, felt like a Honda engine was in there. Would start and idle fine just no power. So after a while found it you pumped the primer for the fule system the problem went away and would come back for a while. I checked the filters for double gasket, checked for air leaking and couldn't find anything. Any suggestions?Thanks Josh Quote Link to comment https://www.bigmacktrucks.com/topic/35177-ch-600-power-issue/ Share on other sites More sharing options...

bbigrig Posted March 27, 2014 Share Posted March 27, 2014 Gear driven fuel pump if filters are ok. I had one fuel pump come and go with stalling issues on an E-Tech engine. Pump was the issue.

staxx Posted March 27, 2014 Share Posted March 27, 2014 Check supply pump drive gear for slipping or internal gear damage on supply pump. Also check return check valve/overflow valve , make sure its not stuck open with debris or weak check valve.
