The list comes through again! Special thanks go to Tim, Sam, Ken, Patrick, Ken & Joel for lots of steering me in the right direction type guidance. And a special "you nailed it exactly" award goes to David Beierl whose email I got this morning identified the exact problem as follows:
>Single connector where wire leaves the harness at right-front of engine room?

>david
After a couple hours of diagnosing with no luck last night, it all came down to a confusion with reality and the wiring diagram. Typical! According to Bentley, the wire leaving terminal 87 on the fuel pump relay and going directly to the fuel pump is white, which it was. But at the fuel pump the wire had somehow changed to black. Decided to try and trace this wire back from the fuel pump. Figured it would end up in a harness and there would be more AARRGGHH. But low and behold it's just a single wire all the way back into the engine compartment where it ends in a yellow spade connector which just happens to have a white wire coming out the other side. Long story longer, the male connection on the back wire was badly corroded inside the crimp. It's amazing it ever worked. So put that one away in your list of Vanagon trouble-shooting things to remember or better yet go fix it before it becomes a problem.
Thanks again volks, you saved my weekend!

Dang it!
Just completed a topside restoration in the engine compartment late last
night. Your basic clean things up, throw some paint around, new fuel lines,
a few new coolant hoses, etc. Went to start it up around Midnight and had
no fuel pump action. AARRGGHH! Was too tired to spend much time diagnosing
it last night. I'm going to hit the archives too but I'm looking to save
some time by asking. Jenny and I have a camping trip planned for this
weekend that we'd sure like to make. Can't help but feel this is something
stupid. I'm looking for general wisdom related to the fuel pump circuit and
what causes it not to get juice. Help! Please!
Here's what I believe I know:
- '86 Wolfsburg Westfalia, 2.1, Automatic, 98,000 miles
- Was starting and running fine before I brought it into the shop weekend
before last.
- Never had a no-start problem that was fuel pump related on this van.
- Never had an ignition switch related problem with this van.
- Tested the fuel pump and it's fine.
- Good strong battery.
- Swapping out the fuel pump relays made no difference.
- Swapped out the AFM and pigtail (don't know if this would matter) no
difference.
- I can hear one of the pump relays click off after the usual few seconds
with the key in the run position. Inclined to suspect circuitry between
relays and pump?
- Dash lights look normal.
- Engine wiring harness looked to be in pretty darn good shape.
- All engine compartment grounds are now cleaned again.
Oh please please please great list members, what the heck should I look at
next? What, if anything, can I eliminate besides the pump itself?
