Thanks a bunch, I would be completely lost without this forum!!

There is another way to power up the fuel pump and injectors for test purposes only. You will need a triple jumper wire.
The DME relay has two sets of contacts to supply 12V to injectors and fuel pump.
Terminal 30 is the battery voltage
Terminal 87 for injectors
Terminal 87b for fuel pump.
So if you pull out the DME relay, and looking at the socket side,
If you put a jumper across 30 and 87b, it will turn on the fuel pump.
If you put a jumper across 30 and 87, it will power up the injectors.
