Hi guys I am trying to wire my fuel pumps in my rb20det powers Datsun 240z.
They work if I send 12v straight to them from the battery, but I can't seem to get them working with a relay.
I have flowed several different diagrams from
Google with no luck.
My main question is, is pin 18 on the rb20 ecu a trigger with +12v or earth. It currently has no power coming from pin 18. Just need to know its not fried.
Cheers
Mick.
