1977 Bus - Mid-Roadtrip, Bus Won't Start
Posted: Sun Nov 18, 2007 2:25 pm
Alright, I set out yesterday from Olympia, going north on 101 around the Olympic Peninsula in Washington state. Drove through the rain for about 3 hours, stopped for lunch, now I cant get it to start????
I spent all afternoon yesterday tinkering with it, here are the issues and what I have figured out. This is all on a '77 FI with hydro lifters and an electronic ignition.
So I go to start and it will turn over and go for a second and then cut out and die, like its got a fuel restriction. I popped the AFM cover off and moved the contact inside, this turns the fuel pump on, but when I let it go and it falls back into the closed position the fuel pump stays on??? It will stay on until I turn the ignition off. Also the bus seems to run when the ignition is still in the starting position, and will continue to run until I let go and it returns to the 'on' position. Giving it gas will not do anything and it seems to kill it faster. I'm really scratching my head here. Cant find any vacuum leaks. Letting it sit for a while seems to let it run for longer. Since the bus stopped running while it was raining I have been assuming it's electrical this whole time but as I look at what I've been typing it looks like a fuel blockage? Why does the fuel pump keep running after turning it on with the AFM?
AAA towed me to a dealership in Olympia, and I guess my bus will sit there until Monday morning if I can't get it running this afternoon. I'd like to not give them my money though, plus I don't think I trust dealership mechanics. Does anyone have experience with Hansens VW, KIA, Subaru in Olympia?
This bus is really giving it to me, I love it, but give me a break. I've got an hour walk plus waiting for the public bus before I can even start tinkering
