I don't know too much about electricity. It seems maybe the ovp is sending the fuel pump relay a signal to shut down.
Maybe it's coincidence...but twice when i was stuck, i removed the ovp and the car started and i was able to get home.
so i started thinking weak fuel pumps are drawing too much sending a signal to the ovp.
maybe 22 years is the max for fuel pumps, even though the car only has 108k miles.
in the interim, i probably will have to get some banana pins and jump the relay. Fortunately, I work out of the house most of the time...
