I have replaced a lot of fuel pumps in gm vehicles with efi. Never had any issue with needing to prime one more than a couple key turn ons.

Running the fuel pump seperately would be difficult......You need to id the fuel pump wires and also their polarity. If you have a connector near the pump you could to do it there.You would have to add some jumpers onto the connector pins. Not an easy task...

It would be easier to hook up a fuel pressure gauge and see if you have pressure at the engine during the key on 2 second cycle.....

Our fleet of GM work vans went thru fuel pumps pretty regularly back in the 90's at around 70K miles......I changed them all and also did some others.......
