The air cooled engines do not cycle the pump when turning on the ignition. The water cooled vans usually do that due to the turn on ignition pulse. Air cooled uses the air flow meter to check engine operation, not the distributor turning.

Subject: Re: Fuel Pump Ground Location?

Just curious on the ground location out of the factory. I have rewired
the ground to the chassis near the pump on many vans.

Here's and update on the fuel pump problem. The fuel pump has no prime
cycle but is working during starting/cranking cycle and can run the
engine now if manually primed. Given that the f/p relay & pump are good
what could the issue(s) be causing no initial 3-8 second prime mode when
the ign. switch is put in ON position, ECU?
