Fuel Pressure? Fuel Injector problem?

[Pedro]

I dont remember now . maybe not ,I checked plugs ,leads , coils, fuel filter, and checked if i had a wet spark plug ,I know i had good leads to no 1 ,a good coil,fuel last thing was to replace the CPS and i fired straight up.
some say you can still get a spark if the sensor is bad but it may be at the wrong time as it is needed.
Just thought i would mention it as it did my head in at the time

Seeing how it will ignite the carb cleaner I think my spark is okay. Cps is definitely next on my list if injectors dont fix it.

Was excited to get my injectors today until I tried them out. Still not working. Injectors ohm the same as my others around 11.1. Isn't that low? Installed a different map now 1 and 3 fire but not 2. 2 does get spark though. Any other tests to do? Bad Ecu? Bad cps?

It'll only fire 2 injectors at a time. If I unplug one before starting it the other two work.

Have you checked the injector harness and then from where it plugs to the ecu to see if any of the wiring has a problem. or does it bounce from cylinder to cylinder as you remove one for testing?

Also when was the last time the engine timing has been checked? (Crank to Cams)

The wiring all seemed to check out. Timing I don't have a clue about. Probably when it left the factory. Weird thing it decided to work all of a sudden. Not sure why. Had the battery unhooked a while, maybe that did it, pulled the relays next to the ecu in and out maybe that made a connection. Maybe pulling the injector connectors on and off finally made a good connection. I'll monitor and report if it comes back. Bike runs smooth for now.
