My fuel pressure is a little erratic at 1/2 tank by the gauge. Adding 5 gal. gasoline to the fuel tank at this time would take care of any possible error.
The dribble of fuel present suggests power is being applied to the fuel pump.
When you first turn the keyswitch on, for a few seconds, the light gray wire at the fuel pump relay should have 12 volts. This is voltage going to the fuel pump with no other stops or switches.
The orange wire is supposed to be always hot.
