Key on?
Key on?..............................yes
Make sure you have a fully charged battery I ran into that myself
2 things: When you turn the key on, does the fuel pump prime? Have you checked the connections of your cables where they hook to the unit harness?
fully charged battery =ok ........I check all pins in the plugs = ok.......recheck all wires and connection = ok........change data cable=same thing..........my pump does nothing because my system does just ecu no response .............i need ecu for priming my pump
Ok, I think I understand better now. The unit is not switching on. I would run a ground wire from the throttle body directly to the battery and try energizing the "key" wire directly from the battery. Try to isolate the problem.
i run ground wire directly on 1 bolt and and I run red and white wire directly on + already....no change..........very strange
White wire needs to be on crank on and run, not to 12 v constant. Try key switch crank side. Hope I am reading what you wrote correctly.
65Pig, the problem seems to be the unit won't turn on with the white wire on constant or switched 12v. This is odd... What else would cause this?
