Holy shotgun approach 😱
Update: I started replacing parts out of frustration hoping I would get lucky. So far I have replaced the following,
Fuel injectors
Throttle positioning sensor
Crank position sensor
ECM from IDS programmed for my bike
Intake gaskets
Spark plugs
Did a compression check 125psi in the front 130psi in the rear
Nothing changed. Still barely starts! Any suggestions on what I should change next? Fuel pump? O2 sensor? What's left but the wiring harness.
Holy shotgun approach 😱
did you perform a tps reset? must be performed when replacing it along with your new ecm. procedure for 08 and up is:
- Turn on the key.
- Set the kill switch to the run position.
- Do NOT start the engine. Rotate the throttle from fully closed (gently forced closed) to fully open (gently held open), and then back again to closed (gently forced closed).
- Repeat 3 times. Hold each position (fully open, fully closed) for 1 full second.
- Turn the key off and on.
Yes I did a TPS reset but I did it again just to make sure. No changes. Thanks for the suggestion.
Yes everything's good but I decided to test the coil and I am only getting .01 ohms primary and I think spec is around .05? Maybe that will be my next purchase.
Update: I shot some starting fluid down the throttle body and it started for about 5 seconds. So I tested the fuel pressure and was at 10 psi. So I got the parts to rebuild the fuel pump. When I took it apart I discovered the filter sock had completely turned to crap. Anyway I rebuilt the pump and it starts and idles great, I haven't had a chance ride it yet but it looks promising. The old pump was working just good enough to start it but not to keep it running and that's what was throwing me off.
