It's been one month, and I've made no real progress in solving my "intermittent power at fuel pump when turning key on" problem in my '87.
At least one person has suggested the ECU (I've ruled out fuel pump relay and ignition switch).
For those of you who are good at reading the circuit diagrams in the Bentley, can anyone tell me with certainty if the ECU is involved in getting power to the fuel pump when the key is turned to the on (not start) position?
Since I can't use the vanagon now due to not being able to count on it starting, I appreciate any help that anyone can offer.
Thanks,
David
