A new or good used ignition switch can be temporarily installed for testing or emergency (failed switch) purposes. This is a useful spare part to carry and doesn't cost much money. Sounds like your Vanagon runs ok so personally I wouldn't worry about the priming. That said, now I'm curious. Assuming all parts concerned are ok and engine not started each time: if one turns the ign. switch to Ign. on position several times, will pump eventually not prime? (fuel pressure is raised to spec ign. switch turned to Ign. on position 1st time, residual pressure remains at spec) I don't know how this would be possible though. AFAIK, there's no electrical connection between the fuel pressure regulator and the ECU, but just had to ask. < grin > . Neil.
