How do you hotwire the fuel pump?

[Deefadog]

Going to be testing my injectors next week, and i need to hot wire the fuel pump so it on all the time with ignition on so i can raise the metering head to squirt the fuel!

I assume you do this on the relay,with a spade heads connected up, but which slots do i have to use?

Cheers

Thanks mate, good stuff there!

Does not really say how to hotwire the pump though??

use a standard X contact relay instead of the standard pump one. that'll come on when the ignition is on and stay prime'ing

Thanks mate, is that it's actual name?

Im sure if you remove the relay and bridge 2 of the contacts the pump will run. However i dont know which 2. Time to get y multimeter out and see whats what. Or if your one of the few people that can read wiring diagrams then have a look.

I have had alook at the diagrams, i have no idea LoL

Yes two bridged should work, but which two? i'll blow something up knowing my luck!

If i use a multimeter, i can obviously find the ignition live coming in, but how do i find the contetction to the fuel pump? continuity test or something?
