1976 Cummins 555 diesel starting problem
My Cummins is getting harder & harder to start, now requiring ether every time. When we were in MN, we blamed it on gelled diesel & half-filled both filters with 911 to get it started. But now that we've made it to sunny FL, the cause has to be in the engine itself.
It runs just as well as always--65-70 mph all day long--and idles perfectly once started. But if we shut it off long enough to get diesel & lunch, it won't restart without a lot of ether.
A mechanic at TA changed the fuel filters once again and cleaned out the fuel/water separator. His theory was that it is losing its prime--that there should be a check valve near the engine and near the tank. He couldn't find any. Anyone know? He didn't think it was the high pressure pump because it runs well. How do I diagnose fuel line leak/bad check valve/lift pump/injector pump--or something else?
Thanks,
Ted
