as stated, is the fuel pump meant to prime when the key is turned to ACC? i know it did originally
the reason i ask, is mine is not priming. I powered the pump directly (at the pump) and it works fine. It's new so i wanted to double check.
the other reason i want clarification is the builder of my swap harness states that the pump will not prime when the key is on ACC, only once fully turned over? is this true? is this a mk4 thing?
i did search but i'm not getting any clarification as to WHEN the pump should prime. lots of info on jumping the relay etc.
if i jump the relay with the key on ACC, and the pump primes, is that an indication that the relay is bad OR am i just bypassing the signal from the ECU to tell the relay to send power?
with the key on ACC i did test and plug at the pump and i'm getting around 8V. (this is testing the two outside wires, brown and a red/yellow? if i remember correctly) bad relay not sending 12v back to the pump?
