Truckie Harbison Posted June 29, 2022 Share Posted June 29, 2022 I’m working on my son’s Superliner and need some help. The truck had sat for quite a while and my brother gave it to my son to restore just before he passed away. The truck ran fine until a few days ago. It started to act up and wouldn’t idle. As long as the rpm’s stayed above 800, it was fine. I went out to start it the other day and it would only run on ether. Determined the plastic check valve on the left side of the pump had broke. Replaced both check valves and now it will run, but won’t start without ether. I let it idle for over an hour, shut it off and tried to start it again right away and it wouldn’t start. The only way it will start is with ether. Any advice would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
