Subject:Re: Starting problems with 88 Vanagon (Wolfberg Ed) with 90,000 ml

This has been discussed recently. The consensus is that the fuel pump relay
is probably not working. There are two identical relays in the system. One
is called power supply relay. And the other is the fuel pump relay. If I name
them incorrectly please correct me. Basically you can swap the two and see
if it makes any difference to help identifying the problem.

Another cause of the problem is the ECU. Check the ECU connector. Unplug it
and replug it a few times. This may fix a bad connection problem. If it doesn't
you may want to borrow an ECU to see if yours has become defective.
