WMD 7.7 (older model) having problems with fuel delivery
stopping, requiring check of racor
which showed apparent air leak — ie fuel
level low in racor
, then refilled and restarted, then engine
dying again. Evidence now shows leak is closed. But lift pump
not pumping... much clicking, but no suction. Pump
status: preheat switch depressed, pump clicking, engine starts and will continue running until release of preheat switch. Immediately or shortly after release, engine dies.
Questions: is fuel solenoid (governed by preheat switch) supposed to remain open automatically after engine begins to run (allowing release of preheat switch) ? If so, what prevents it from closing... is it electrical
, or positional or???
New problem... just occurred: both genset and main engine ignition switches have abruptly stopped functioning, disallowing any battery charging
. Fuse? If so, what burned it out? Preheat switch depressed too long?
