If you lose fuel pressure overnight (leakage back thru the pump), the injectors won't work until there's pressure again.
Once the pump is spinning, it's fine.............
I didn't even think of that. I guess tomorrow I'd find out since I'll jumper the two connections. If it starts right away I'll be really happy and I'll save up money to order in a new fuel pump and see if I can find someone to help me install it.
