when the ignition switch is turned on, current from the battery flow,s to the fuel pump motor through the side stand relay and the fuel pump relay causing the motor to turn. since the ecm has a timer function, the fuel pump motor stop,s turning three seconds after the switch has been turned on. thereafter, when the crankshaft is turned by the starter motor or the engine has been started,the engine revolving signal is input to the ecm.
THE ENGINE REVOLVING SIGNAL IS NOT GETTING BACK TO THE ECM
CHECK UR CRANK SHAFT POSITION SENSOR
Thanks for pushing me towards electrical. I was getting away from it because more people were telling me they thought it was mechanical.
Anyway, I checked the resistance across the mentioned pins at the ECM and they were incorrect (infinite).
Next I decided to take the PCII out of the equation and as I was disconnecting the it I realized that I hadn't disconnected completely in the past (the two connectors in the pic, my bad
).
After disconnecting the PCII entirely I had the correct ohm reading at the ecm.
I decided to key to turn try the starter button with PCII NOW disconnected.
Now the pressure builds EVERY time I hit the starter button. I can wait 1/2 second or when pressure drops. I've tried every possible scenario and the pressure now builds whenever I hit the button. I've tried it over 20 times and I get pressure instantly. You don't know how much I appreciate this, I thought it had something to do with electrical but I didn't know exactly how the ecm worked. Now I have a little better understanding.
So now, since the PCII is outdated anyway I'll need to replace. Any suggestions?
Does anyone know what those connectors were for, I like knowing as much as I can about my bike.
