I get no return at all, not even damp in the line. I also did two faq tests for fuel pump operation: jumpering fuse 1 to near and far contacts of fuse 11 (pre-pump operates, but main does not), and also jumpering teminal 30 to 87/2 on the fuel injection relay socket (pre-pump runs, main does not). I confirmed 12v across the main pump harness at the pump during the second test above, and also started the car with the main pump harness disconnected. The car ran with the same symptoms I've been getting. As soon as my work location is in shade I'll remove the main pump and try to bench test, but it is my most likely culprit so far.
