fuel solenoid-intermitent and low voltage

[bus2nut]

While driving my motor srtopped.I checked fuel prime and it was ok.
I found out that there was no voltage to the fuel solenoid.I ran a
temperary wire from a relay up front and it has worked since.I have a
3208t installed in a 1982fc in 1995.There appears to be a one volt
drop to the fuel solenoid.The oil presure is 75 psi.Is the low oil
pressure switch tied in to the solenoid and if so where can i locate
it?What and where is the relay that supplys power to the solenoid?
