I have never tried the reverse polarity thing, but have heard that it can work. I would power the pump up from a separate battery using jumper wires with the original wiring disconnected. Obviously have the fuel inlet line disconnected when you do this to get the potential blockage out.

So today, with the fuel pump off of the van I hooked it up with alligator clips and hoses on either end to try and see how the pump was behaving. It does not want to budge and behaves just like the old pump that I replaced. This might be a faux-pas but we had a working fuel pump for an old Land Rover which we tied in. With the hose disconnected at the engine, it was pumping fuel to that point so I don't think line is plugged. And with said pump we tried to start the van for 2 seconds, but no dice. Even got it to fire with ether again to try and see if it might pull fuel better, but no dice. Fuel injectors? Is there a fuse? Something come unplugged maybe.........I still think my pump is hooped but also feel there might be an underlying problem with fuel

Unless your old Landy was fuel injected, that pump is very unlikely to work. Most electric pumps for carbs run around 3-5 psi working pressure. Your bus requires around 30 psi. If the fuel pump is seized up, then you must deal with that. Note that stale old fuel happily plugs up fuel pumps... Did you try the reverse polarity thing yet? Taps with a hammer???

Yes I tried the old hammer and reverse polarity trick....Not sure about the rover pump. I think I see a new fuel pump in my near future. I'm going to soak the inside of pump overnight and try again tomorrow maybe

Sooooo......It was the fuel pump. Mr Brent Petrie lent me his working pump to try on my van. After a few cranks on the key she fired up!

I don't know how or why......but I put the old pump back on to hold the line while I began the search for a new pump. Just for fun I wired it up and of course the dang thing fired up first go. Let the van warm up for a good 10 minutes and took it for a spin around the farm. Runs great and the booster/vacuum seems to be solved with the new booster. I don't how well I would trust this pump, but sweet crap what a great feeling to have this gal running.

Ok....new problem. I was able to drive the van around for the last 4 nights, but when I went to fire it up tonight she would not go. Sounds really sluggish and a loud clanging as I try to start....Any ideas of where to start looking? Am I just playing with a tired old battery?

Loud clanging while cranking??? Make sure your battery is all charged up and try again. Dead batteries can cause an odd noise when the starter solenoid tries to repeatedly engage but cannot crank...

I feel like there should be enough juice in the battery to fire up....it's measuring 12.1 on my little doohickey.

FWIK, you might have the proper voltage, but that does not mean the battery has the amps to crank the starter properly. You need to get it load tested(with a load tester, not a little doohickey ) to be sure.

Even 12.1 on the doohicky is too low. But I agree. Need to properly test that battery. I bet it's hate'n it. B

So I charged the battery up and tried again. I tried it twice with the same result..........Clanging has stopped, but still a really sluggish sounding van. I wouldn't even say that it is firing and sounds more like the starter or something else just spinning. Also both times it backfired right away and died.

First off, it's a bus, not a van, lol Secondly, whenever a fuel injected bus coughs and farts, check all your vacuum hoses. Thirdly, I don't have a clue without a lil more info. We have a meeting tonight at Southgate Timmies. Come bug the crew and see what we can come up with
