I just hooked up my fuel pump and ECU today, but I dont have a motor installed. Will these work without a motor installed?

is the engine harness installed? Id say if the harnesses are plugged in the pump would prime. make sure too hook up the grounds, I know the fuel pump wont prime if you leave the T-stat ground off.

I could be wrong :P

 

yea i think your right

 

yup, as long as the engine harness is plugged in and grounded it will prime the pump.
