its not old - I'll charge it up and test.

I will check all these things - I am very happy its most likely not the ECU - i would have been very sad if had bought a replacement one and not fixed the problem.

I will double check - i couldnt get a reading off the cable the sensor plugs in to. I came to this conclusion as I had hoped that the sensor was the issue, it's not, there is something else going on. Will have to check the ECU.

everything that should happen does happen - except for the spark. lights, fuel pump, instruments all good. It sounds like it should - just does not kick over. I am now thinking ECU, as far as i can tell everything else is good

to day i checked everything, replaced everything i could, crossed my fingers and tried to start up my bike again. it didnt start. i posted asking for help with the bike stalling and not starting again, i replaced the crank shaft sensor, i have checked the coils, all the connections, charged the battery, checked the kill switch and side stand switches, checked and replaced relays and fuses. and it still does not go. i am not sure where to go from here. Stator? earths? loom? some other thing. I will post up when i find the solution.

i used one of these did the trick! sadly- i have no power to the sensor...

that tool is genius - I will see what i can put together.

update - Got the new sensor and installed it. still not sparking. i dont know where to look now - when i took the old sensor out it was quite swollen, the oring was mashed up. it had three plates to set the air gap. My guess is that this air gap is too big?, how do i check it? i also need to check the o-ring, i have a feeling that the new one i installed is too thick - the new sensor did not come with replacement. Do any of you know the oring specs?

i found it on this page - $15 usd each. https://spareto.com/products/meat-and-doria-sensor-crankshaft-pulse/87074

done! https://spareto.com/products/meat-and-doria-sensor-crankshaft-pulse/87074 I found them on here, the cross reference section is really useful for confirming i got the right thing

that description fits perfectly - bike would run worse as i approached work or home, (about 25ks each way) but would start fine. The idle had started to wander - it sounded like it was searching for fuel, and would stall at the lights every now and then. when i last had the bike running it was to warm it up to balance the throttle bodys and tune it. was treating the wrong symptom. Now that you mention it, the sensor was really hard to get out, i had to get some fuel hose pliers to get enough force on it. I didnt know to check for swelling, i'll take a look at that when the new one arrives. need to find the right sized o-ring for it too.

I found and ordered a couple of those 13 euro each. about 30 euro postage. ( 90 australian delivered)

Hello - after about 3 years of trouble free riding I started my 2002 Scura up a week or so back to head out,for the day and it stalled. its not started again - whenever i try the bike will just spin on the starter. fuel pump works, all the other electrics work but there is no spark. I have checked the plugs, coils, HT leads, relays and fuses - all were good. I then checked the crankshaft sensor, the resistance between the poles was in spec, but despite a few efforts i could not get a reading from the sensor itself. the TPS tested in spec - i havent checked the voltage though. My guess is that the crankshaft sensor is cooked and that i need to order a replacement, if its not that what else should i be checking? the bike has a few mods to the wiring, the fuel pump is on its own fuse and i have added a few additional earth wires that keep it going and charging well. any help or suggestions greatly appreciated.

ahh - good question. wire that you would use to earth the battery. i never thought to ask, or that there was so many different wires

as soon as i earthed the reg to block the electrical issues stopped.
