no run problem

[4X4longbowhunter]

Going to my day job yesterday my '88 BII started loosing power like it was running out of gas. Took my gas can to the station across the street,put two gallons in,and put this gas in the tank. No start. Went back,two more gallons,still no start. (I'm the one with the previous post of thinking I had a ten gallon tank. I drove my Bronc about 100 miles past empty and started thinking about a possible float problem on the sending unit.) Now the bee-ach won't start. Had the thing towed home and started looking for some obvious things. First thing I checked was the fuel pressure at the schrader valve on the fuel rail. Not having a fuel pressure gauge to use I just took a metal pointed pick I have in my toolbox and opened the valve. Just a light bit of air-no quick burst of gas shooting out like normal. Hmmm...no fuel pressure. So what is the best way to check the intank and the frame fuel pumps? Think the tank pump is gone? Or maybe something else?

Pumps only run for 3 seconds when you turn the key on without the engine running. Cycle the key a few times, release the air pressure at the schrader valve and it should start. Listen to see if you hear BOTH pumps running, one in the tank as well as the one on the frame. If either one dies it will not run well, if at all. Rear is (obviously) a pusher and it does about 19psi and high flow, front one is high pressure(it'll do 80 psi if you choke off the regulator-not recommended)and should do a continous 30psi or so depending on which of the three regulators you have, keep us posted on results.



Oh, you can check fuel pressure with a tire gauge if that is all you have.
