Can the main computer shut down the Bosch VP44 if there is a cooling problem or temp sensor error? I have been having cooling problems on hot days and under load. After flushing radiator, the engine ran normally for 5 minutes down the freeway and then suddenly stopped and wouldn't start. (as if it ran out of fuel) . Fuel pressure from lift pump is OK. Fuel to the injection pump inlet OK but nothing at the injectors. There was no missing, no smoke, no roughness, good 23 mpg, just before shutdown. Coolant temp was normal. It seems odd that the VP44 would fail after I was working on the coolant system. Is there an internal fuel shutoff solenoid inside the VP44? Any insight would be appreciated!
