Hi everyone.
my bike won't start and im hoping to fix the problem through a process of elimination.
-there is spark and petrol is reaching the plugs because when I pulled the plugs out, they were wet.
-when i press the ignition, the starter spins but the engine won't turn over, and the engine will eventully backfire (a single loud backfire).
-pulled the ecu connector and checked for continuity with the sensors, all wires appear to be ok
-measured resistance value of the collant temperature sensor, a value of approx 2.6.
tested the resistance values at the airflow mass sensor , all values match the information noted in the troubleshooting section of this website. one minor concern, when i measured the resistance value of the sensor at pins 8 and 9 it was approx 198 ohms, and when i applied hot air to the sensor using a hairdryer, the resistance value changed to approx 184. my understanding is that the resistance decreases as the temperature increases. there was a small reduction in the resistance when i applied hot air to the AMS.
is this correct, and if not, is the unit faulty?
i will test the hall sensor asap. thanks for the info on this website. very helpful.
