Re: 2002 f4i no spark or fuel pump HELP
The ecu is not providing a ground to the coils or the fuel cut relay...most likely the injectors too.
I need to figure out why the ECU is not providing these grounds. Without them these components will obviously not work as they should.
What would cause this!? I probed the zener diode at the ECU and I get 8.6V so the bike can't possibly think its being stolen.
i would check the ground wires on all of the above and make sure you don't have exposed wire or broken wires anywhere. just trace them and look over them really well cuz they could be touching metal somewhere and shorting out.
