'93 gl-1500. 62k. new OEM fuel shut-off valve, new fuel filter. added a spliced ground wire from the gnd. on the fuel pump, to the main ground under the seat. just to be sure it was getting a good ground.
i'm getting instant fuel flow to the fuel filter.when you turn the key on. i;m getting instant vacuum to the fuel shut off valve, when you crank the engine.
but i'm not getting any fuel pressure at the fuel filter, checked with a gage.but plenty of fuel flow.
anyone know if the fuel pump is suppose to register pressure or only fuel flow.
the ECM wasn't giving power to the fuel pump 6 months ago, so i ordered one off of e bay. but it didn;t either. so i added a hot wire from the left phillips screw over the fuses. (hot when the key is on) to the left storeage pocket. then added a 5 amp mini-fuse, then a on-off switch, then goes to the hot connector on the fuel pump. this set up worked ok for several months..
i'm tempted to eliminate the fuel shut-off valve to see if that helps.
i also added a new ground wire on the right philleps screw to the main ground under the seat.
