BMW R1150GS single spark plug 55K.

Hello,

Bike is used everyday didn't start this morning found there is NO SPARK.

Good battery, good HT leads, fuel pump is working, injectors spraying, engine is spinning.

JohnGS1100 chip and Nightrider AF-XIED O2 sensor shifter installed.

Where should i start?

Many Thanks,
Andrei.

Take the tank off and check all the connectors.

Thanks for quick reply! How to check? Unplug, spray with WD40, clean, plug back?

Coil or pick up are obvious ones. Take no spark on either plug ? start with simple things first though.

What did you do last when it was working ok

No spark on both plugs.

Worked fine yesterday. This morning was going to take it for MOT. Put Nightrider AF-XIED into leaner settings before start and it didn't start. Performed Motronic reset with FUSE 5 10 mins out.

Spray QuickStart into the induction inlet whilst spinning her.
No spark and she won't fire, no fuel and she'll run as you spray.
So process of elimination.
I reckon she'll start and then run fine as her plugs may be wet.
I have done this a few times so don't shoot me

Fixed! Removed Coil, tested secondary fine, primary no readings. Cleaned connected and got some reading and spark. Will probably order new coil. Thank you for quick replies!
