Meant to say it hasn't started and stayed going yet today.

Tried the jerry can. Maybe my lift pump is done because there's some fuel in the line but not much. And there's nothing at the fuel filter at all now. Interesting that the return line still has fuel in it. Getting dark now. Try again in the morning.

Did I say that this is really annoying.

Put some clear line on and cranked it 4 or 5 times. Barely any fuel in the line. I'm going to try to get it started with a 5 gallon jerry can.

The really weird thing is that when I try to start it there is more air than fuel going through the return, but when it was running yesterday there was very little air in the return line.

this is really annoying.
try unplugging your advance on the IP..... and maybe upgrade to a electric lift pump.... princess sells them for like 70.00..... and redo all the lines in good rubber, double clamped.... i would look at dropping the tank too... maybe the sender lines are rotted and pulling air...

If you mean light load advance that hasn't been functioning since I broke the wire at the sensor last year when I was replacing an injector. I've bypassed the fuel tank at the moment and the hose from the jerry can to the fuel pump is new clear line. I have a temporary electric pump in line but I've lost the alligator clips to try using it. I'm going to try that first thing in the morning, I forgot it was there until I had given up for the night. If that won't draw fuel from the jerry can a cigarette may get left near a puddle of fuel.

And there are lots of puddles, clear oily puddles, black puddles, red puddles. No green puddles tho. Now that I say that my rad will blow on me once the bitch is started. It's funny. A month ago a guy was walking past my truck while I was taking a break and asked me what year the truck was, Oh '87 huh and still reliable huh? I said yeah not too bad. Guess what started happening a few days later.

Lack of progress report. Electric pump wouldn't draw fuel. it partially fills the clear line then won't draw anymore. I put a finger on the suction side and I can feel a bit of suction but not much. Tried to gravity feed. That wasn't working either. Enough to fill the filter but that's about it. Removed the mechanical fuel pump, looks fine, and when I cover the suction end with my thumb and push the lever I can feel some suction. Again though, not a lot.

Saw a drip come from the bottom of the filter base but there's been so much spilled fuel that I don't know if it's from the filter base or not. Regardless I still ahve to figure out why nothing will draw fuel.

Is this from a jug or the tank?

Both pumps bad?

Jug and tank both. I;m almost certain that my mech pump is bad but it's passed the air bleed test when it was running. Air bleed open and good strong fuel flow, and no hesitation in the engine. Went and tested the electric fuel pump at my mechanics shop and it pumped a litre/quart of fuel in 30 secs. But that was flowing down and at home I'm flowing up so I thought maybe if I raised the fuel jug that would help, whoops some fuel sploshed out and got on the connections, bunch of sparks and smoke and melted wires. Pump is definitley bad now. So put the mechanical pump back on (what a joy) and bypassed the fuel filter using an inline filter but still no fuel flow. I'm stumped. Have a new mech fuel pump ordered for tomorrow morning. Cross my fingers.

I'm starting to think there were a few fuel problems and the last one was the straw that broke the camels back.

took a look at a '90 with a decent body and 305 today. $800. It's very tempting. Park the old bitch and try to find a new body or something. Hard to justify the time for a truck that is such a piece of junk.

Buy the 1990 and stick the 6.2L in it! Itll give you a good chance to run all new fuel lines new wiring for the lift pump, etc. Good chance to start clean.

Good luck in whatever you end up doing. I wish I could be of more help
