Another warning, learned by experience...
Even with plenty of fuel in the tank, leaving the fuel pump on overnight will kill the pump as well as flatten the battery.
(I have my pumps wired direct to by-pass master switch and contactor failure)

David,

 

I normally shut down my engine by turning off the injectors, followed by the fuel pumps, coils, etc.

Isn't your tank vented?  Shouldn't be able to pressurize it.  Maybe you pressurized the fuel line with some air?

Long story short,  standard eng. shut-down,  main fuel pump switch to OFF,  half second or less,  eng. quits rather quickly.    """UNLESS"""   you are low on fuel,,, & picked up some air in the lines,,,  eng. remained running,,,  after shaking the thoughts of gremlins out of my head,  possible as long as 20-30 seconds & quick look at fuel gauge for tank I was on the thought came to me that I picked up air from empty tank & pressurized it with fuel pump, I now have an air pressure-fuel pump backup sys. so eng. will remain running, had to shut down elect. to stop eng.  How about that one to start the year.   David R.
