I have had the same issue and used the few seconds of run time on each start up to limp home 4miles away .... 1/2 mile at a time.
As for what else can cause this? I can only think of fuel pump #1 or relay.
If these pumps are run AT ALL outside the tank for any reason it compromises them. As for the test lead use as power to #2 pump that won't work.
The way the test lead is wired into the relays as soon as you put the key in the on position the test lead is out of the circuit.
I ended up putting in two emergency switches.
One to put power to the test lead for a pressure test and
one to the FP #2 at the relay for a way to get pressure if #1 fails.
