hayabusa firing but wont run, will run on easystart
« on: July 07, 2018, 02:56:11 PM »
okay so i have a hayabusa engine in my fisher fury, its sat around for about 4 years, gave her fresh oil, new fuel lines, got rid of most of the stale fuel in there, it will fire and try to run but wont stay running, it will run on easy start if sprayed continusly. I put a set of new plugs in also, it is getting fuel to the injectors as have had them out and they are spraying but unsure if it is enough as it must be most certainly fuel starvation, ive had apart and cleaned the motorcycle fuel pump no problems there.
Could this be due to a sensor of some sort or a fault in the ecu?
any help would be great

Adjust TPS, check fuel pressure

Is it Gen1 or Gen2 engine?

Suggest having the injectors cleaned/flow tested and check fuel pressure at the rail.

i believe that every bike should have a fuel pressure gage on it, turboed or not
alcohol is the cause and solution to all my problem,s
