well i searched a few older threads and found some ideas but still having a this problem with my 86 bii. Yesterday on my way to work my truck stalled out twice, since my gas gauge is broken and i went 4x4ing the other day i assumed i burned more gas than planned and put a gallon in it from my little spare gas tank. got to work fine, started after work just fine and halfway home died in the middle of the busiest intersection, after a big scene and being pushed by a state trooper, i checked to hear my fuel pumps and heard nothing, checked the inertia switch its was good, checked the relays, got out test light, power is at the fuel pump relay. so i checked it at the FPIS and got nothing, checked power to the high pressure pump and nothing. if i got power coming outta my relay where does that wire go next? cause that's were i am thinking my problem is, cause power is lost before the inertia switch.
Well to get home from the parking lot i ran a speaker wire from a fuse in my fuse box out the door and to the + on my high pressure pump, it got me home and into the garage this morning but i don't wanna keep running it like that, and i don't here my in tank pump like that, don't wanna risk burning up the high pressure pump. i ran a jumper wire to the inertia switch and heard the high pressure running, but not the low in tank, but it was loud outside and could have missed it, i checked pressure on the rail and there was a lot of pressure, could feel fuel pumping through the lines, tried to start it and it wouldn't fire, the high pressure pump was running for sure, but by a jumper wire to the FPIS. could my in tank pump be bad and cause the power loss to both pumps? any thoughts thanks for the help.
