So the bike is pretty stripped at the moment and I do not see any wiring issues. I'm going to pull the flywheel cover tomorrow and make sure the flywheel is not loose. My thought is maybe its loose and the flywheel is moving on the shaft just enough that the cps isn't reading it properly. Its possible the times it did start and shut off, the flywheel started in the correct position and moved. Worth a shot. otherwise I'm going to purchase a used wiring harness and see if that fixes it.

CPS air gap is good. flywheel with jam nuts are torqued properly. Rectifier looked fine as well and is not shorting to ground.
I pulled the entire wiring harness and did not find any obvious cuts, frays, or abrasions on the insulation.
My only other thoughts are order a used harness and try it out or corrupt ecu(dp ecu for full Termi exhaust)

Any other suggestions?

ok let me summarize the issue again.

the first time it happened was 4 weeks ago. I was on the highway for about 45 min and as i was giving it throttle off an exit ramp, the engine just quit. The dash never blinked and stayed on the entire time. I coasted to the shoulder and tried restarted it. It would start and die right away. Voltage was strong, lights, etc were fine but i got an immobilizer code. I pulled my cf key ring off and tried starting it again. the immobilizer error went away but the bike still started and shut off right away.

I get it towed back home and let it sit overnight. The next day, i tried starting it and it would just keep cranking. Normally the servo assist start would stop it from cranking after so many revolutions if it doesn't start. Again, voltage was strong as I keep the bike on a tender. I tried a newer battery from a friend's bike and same issue. I check all my grounds and wiring connections(i have the wiring upgrade) and did not see any corrosion or loose connections. I also removed the fuel pump and checked the hoses and screen. Everything was fine. No cracks and the screen was not dirty. Filter was replaced last year along with the hose clamps. The fuel pump primes when i turn the key on and I can smell fuel out the exhaust eventually after cranking. plugs seem fine as well(read on, they wouldn't stop working then start again, right?)

The fact that it would start and die right away previously and now it kept cranking without firing, had me thinking something to do with the CPS since that's the only thing that tells the ECU anything timing or rpm related. I decided to remove my bazzaz(at this point it was only being used for a quickshifter as I have not yet had it tuned). After removing the bazzaz, the bike started running again. However, this was a false alarm.

I rode the bike the next day and it took me about 30 minutes away before the same thing happened(although without the immobilizer code this time). The engine just stopped firing as I was moving. Again, I tried starting it on the side of the road and the same thing. It would fire up and die right away so I tow it back home.

Yesterday, I swapped the cps with a spare and checked the air gap which turned out to be fine. Still no luck. I left off with removing the entire wiring harness to check for obvious breaks or abrasions and found nothing. I'm back to being lost. Any suggestions?

Things I've ruled out:
battery
rectifier/regulator
kick stand sensor(it shouldn't crank at all with a faulty sensor)
CPS
fuel filter/hoses(possibly weak pump?)
TPS(reads smoothly in JPdiag)
belt tension is fine


below are the latest codes I am seeing and has me thinking harness or corrupt ecu(DP ECU for 70mm termi)

going to try another ecu too
I tried 2 different batteries. My first thought was battery/RR.

The cranking issue; check the starter solenoid/relay loose connection perhaps. Since you installed the new cable set.
I'm pretty sure they're tight but i'll check again.

interesting. i thought it was crank sensor related since it tells the servo assist how many revolutions it's done.
I'll check it anyway. i'm open to anything at this point lol.
thanks for sticking with me on this.

ok so I swapped out the starter solenoid and it does the same thing. i'm wondering if its an intermittent fuel pump. but it starts up and dies right away even if i don't cycle the key to reprime the pump. Also, I can smell the fuel out the exhaust.

not yet. i only have access to aa dp ecu from an 1198s...would that at least get it idling? I know the fueling will be off.
