History:
I have had the machine for 11 years and it has been trouble free until now.
I bought the machine with a bad engine and rebuilt the engine in 2013 when it had 5719 hours on it.
Complete rebuild with the exception of the injection pump and I did have the injectors pop tested and they were fine then.
On 8-17-2023 at 5994 hours I drained and cleaned the fuel tank, replaced the lift pump and both fuel filters.
It now has 6019 hours on it.
I was using it the other day and it was running fine like normal.
I went out a few days later to use it and it would crank but not start or run.
Machine Information:
Model Year 1992, Machine PIN JAF0101469, Cummins/Case 4B3.9, Engine S.N. 44702207
Injection Pump Lucas CAVDPA/DPS
Troubleshooting Done:
Checked for voltage at fuel shutdown solenoid with the key on and while cranking, had 12 volts in both conditions.
Cummins manual said if both of the above conditions are good the fuel shutdown solenoid is bad so I replaced the fuel shutdown solenoid.
Used lever on transfer pump to verify fuel supply at the fuel bleeder on the filter housing and at the bleeder on the top rear of the injection pump.
Both locations had fuel and no air coming out while manually pumping the lever.
Cracked one injector line and cranked engine, nothing but a drip came out.
Tried to start the machine after this and nothing, cranks but won't start or run.
Current Situation:
I have given up for now trying to start it until I hear back from the Guru's on this forum.
Looking forward to hearing what you guys have to say.
Thank you,
Gary
