f4 to f4i unknown issue
Re: f4 to f4i unknown issue
ok this is frustrating because I am not able to ride, but its fun coz I learn lots
so as I said before, I have on my bike everything from F4i - wiring harness, cam with cpg, throttle body, etc
my problem I guess its electrical ... what Ive done today:
-bypassed the bank angle sensor by bridging the two wires
-checked to see if the fuel cut and engine stop relays are good - they are good
-checked to see if I have voltage in the engine stop relay - 12.7 V
-checked to see if I have voltage in the fuel cut relay - 0 V !! WTF ??
from the f4i wiring diagram my understanding is that the engine stop relay should be powered in order for the fuel cut relay to be powered and then the ecu to be powered (the Bl/W wire from fuel cut relay goes to the 6th pin from the black connector of ECU)
if the fuel cut relay is not getting any power the ecu is not powered either
anyone agrees or I am talking **** ??

Re: f4 to f4i unknown issue
done everything besides the stator plug (which I connected directly to regulator plug) and thermostat housing - I guess this is why I couldnt find the ECT sensor to plug my ECT connector in ....
Re: f4 to f4i unknown issue
so the fuel pump isnt priming? and u jumped the red and green wires in the bank sensor right? ill bet ya i know whats wrong... the ignition! if your using the f4 ignition it doesnt have the resistor for the pump relay in it like the f4i...the f4i is 4 wires...one being pink... sucks but ill bet thats ur problem..

the pink wire goes from the hiss antena directly to the ecu and the ignition switch has only 3 wires (for US model the 4th its the pink one - but in US there is no HISS **** )
I do have the F4i ignition and I've measured the tension on the pink wire there are about 6 ohm, but no power - I guess I should have 9V sent to the ecu
