Thanks for the pointers. Funny you mention the pump relay ground, as that was an initial problem. I had no power to fuel pump and found that the ground ckts for both the pump relay and cold start relay pass through the #8 multi pin connector and into the engine bay. I could not get good grounds through the connector so had to ground them near the relays themselves.
It seems that this is a gravity fed pump, correct? With fuel line from tank disconnected, fuel flow from the outlet slows until compressed air is introduced into the outlet tube. I will try and remove the tank filter screen as that might be the problem. Can the filter usually be removed from underneath the car without removing the tank?
Thanks BB
