Hi all,
Just finished putting my bike back together after getting the frame back from having a little repair sorted. I'm pretty sure everything is connected back together correctly! When I press the starter, the engine turns over on the starter motor, but it doesn't start. You can hear the fuel pump prime when turning the ignition on, but when I use a spark plug tester (or hold the plug against the engine) there's no spark on either plug. The coil is plugged in with the three-pin connector to the loom. The 15A fuse 'E' is okay. Any suggestions? Cheers, Andy

The tip-over switch maybe ?

The tip-over switch is one of the things I hadn't disturbed.
I just took it off and reconnected it, it 'sounds like' it's working when you shake it. Would the starter motor turn over the engine if the tip-over switch was 'on'? The fuel pump is priming too - I didn't think it would if the T/O switch was in 'fallen over' mode. Cheers, Andy

A bit of an update:
Using my multimeter I get good readings from the crank sensor (mine has two pins) - 0.88 ohms on the winding and 2V AC when turning over on the starter motor. I couldn't find my test lamp to test the camshaft sensor. For a moment I thought I'd connected the crank sensor and coolant temp sensor the wrong way round (the connectors are identical) but the wiring diagram colours match up correctly. Any ideas what I can try next? Cheers, Andy

Thanks for the pointer mate - I eventually tracked down the fault - your suggestion is the closest, there was a break in the loom of the orange/green wire from the cam sensor back to the ECU. I spent two hours testing sensors and wire continuity before I found the fault.
Cheers! Andy
