I running my truck the other day and it ended up just choking itself out and dying. After a quick investigation I noticed when priming before starting I could no longer hear the high pressure pump that is mounted on the frame. But I could hear the the pump in the fuel tank.
my question is: Is the lift pump (in the gas tank) and the high pressure pump wired in parallel? I plan on checking voltage to the pump and then giving direct power to the high pressure pump to see if the issue is the pump itself. But I was curious that if, in fact, they are wired in parallel it would be a fair warning sign that the one of the fuel pumps might have an internal fault if you can still hear the other.
