Guys good morning,
please, have a look here and share your wisdom please. Bike is a 1998 1100 Gs anniversary
Rode for 15' yesterday in heavy rain, no problems whatsoever.
Today in the morning, bike didn't want to fire. Checked the left plug, it fired, so put it back together, gave it another shot, and it did fire. So off I went, until I stopped and then nothing.
So, I did the following checks:
-pump primes fuel: if I disconnect the fuel feeder to the injector and turn the ignition on, fuel comes out just fine.
-fuel is not coming out of the injectors: I removed the injector from the throttle body, fuel line and cable connected, and cranked the bike. Nothing came out. This is the case for both injectors.
-injectors seem to be fine: with the fuel line on the injector, I removed the cable, turned the ignition on (in order to rise the fuel pressure) and gave the injector 12Volts for an instance. A nice fuel spray came out of the injector. I guess this also means that the fuel pump is fine as well (nice healthy fuel pressure).
-All fuses are fine. Everything else works, and the starter cranks the bike happily.
To be frank, I didn't check it for spark the second time but I will. However, I guess that the problem is that no fuel is coming out of the injectors, and this is because the respective signal is not arriving to the injectors.
So, in my mind, it can only be motronic, that stopped transmitting to the injectors, or the hall-effect sensor that stopped transmitting to the motronic. In the hall-effect scenario though, I should expect no spark as well, isn't this correct?
Any advice, on possible causes or diagnostic tips, would be more that welcome!
Thanks in advance!
(I should probably add that a couple of weeks ago I had some ignition-switch cable issues, but I fixed them).
