Subject: Re: Fuel Injection Help NEEDED!
Bill -
I have a '80 Westphalia, and similar problems with lack of power to
the fuel pump, was related to the Fuel pump Relay not being grounded
to the body. I can't remember where it was on my '76, but on the '80
looking into the engine compartment, against the front wall, upper
left, it's a aluminum housing with a bunch of white wires.
Check the screw holding it to the body, it can't hurt to re-attach
it to the body, good luck.
Re: Bad ignition switch, I've changed mine twice and the problems
didn't go away until I put a solenoid relay between the start switch
and the starter, (like I did with my '64 deluxe years ago) due to age
affecting the ability of electricity to travel long wires in an older
vehicle. Although the ignition switch is cheap and easy to replace
in an '80. If the solenoid didn't work I was going to completely
rewire a entirely different ignition switch and avoiding the steering
column. Good Luck.
I had a '76, loved it, 20,000 miles in 4 months, no problems, very
reliable, wish I hadn't rolled it in Manitoba
(of course I then drove it back to Seattle to be totaled by the
insurance company)
