my fuel pump relay turns on but does not send power out of the red/black wire that goes to the fuel pump. i had it working last week and now it dosent work. what could be causing this?
put power across the primary side to actuate the secondary side and check the resistance through it. If you have a sh*t load, then its bad, get a new one.
