Run 12v to the fuel pump to make sure.. It could be a bad connection to the or a bad fuel pump..?That's what I figured but already checked both those and still no fuel pump cycling. I'm guessing the only thing left is the ECU...agree?
I had the quad on the dyno, tuning the Procom for a big bore kit and head porting. It was making the 3rd pull and just went dead then powered back up. I shut it off and when I tried to fire it back up, no fuel pump cycling. Lights (FI for 3 seconds, and neutral) come on, it turns over but won't start.
Make sure your battery is fully charged,,12.8v standard..I had already ran 12v to the pump and it worked fine.
I checked continuity on the r/wh wire from the relay to the fuel pump to the injector...good
The r/wh wire is the power to the pump and injector. I don't understand how it's "energized"? There is a "door" (contact) shown on the relay drawing. There is power on the other side of the contact but what makes the contact close to get power to the red/white wire?
If no code is showing up, then your crank sensor is fine...Code 21 see pictureBattery is at 13.5 volts and always on battery tender when not using
Cannot confirm spark right now. I have new stator/crank sensor coming due to bare wires I found when looking for solutions. That was the reason for originally starting this thread...lol
Swapped out relay with a new one I have and also with one of the others...no fuel pump
Plugged in stock ECU and no difference. (FI light comes on for 3 seconds then off)
It almost seems like the rollover sensor or some other "safety" feature is activated but I've swapped out the roll-over sensor and soldered the kill button wires together previously. (I use a tether for racing) Could there be other items which would interrupt the start sequence?
