Fuel pump not making a sound?
Hi Guys
So I've just replace all the wire harnesses from auto to manual conversion and now the new fuel pump is not priming? I had spare relays and resistor from running car and no go. I'm thinking I might of not forgot a grou d in the circuit? Any help would be greatly appreciated .
Thanks

New update. So I bypassed the ground to f/p located in diagnostic box and it started. What do you guy think, any ideas?
Thank you

Anybody have any ideas? As I mentioned earlier both relays and resistor are good. The only way it will start to prime or make a sound is if I run a wire on diagnostic box from Grd to f/p .
Thanks

Thank you for your time
