it is NOT a CAR
and no maker told YAMAHA WR-450 ?
and bounced the WW key to make googling it go crazy wrong./
so why post MC to cars?
not sure me if the ECU on thing EFI injector bike, has scan tool port
but the service manual would cover that. why not buy one?
no fuel to the injector.
engine is ok
spark is ok
so fix dead fuel
and why fuel pressure is zero I guess, the service manual is your answer.
Check for spark to the sparkplug. Try a shot of starting fluid as having gas pumping and having the fuel injectors opening are 2 different things. If you have spark, then the fuel injectors may not be working. Quick diagnosis is to use starting fluid and see if engine tries to run. This indicates problem is not lack of spark but lack of fuel getting into cylinders.
Did car run out of fuel? If so yoou may need to get rid of air lock. There is a fuel rail on the top of engine with a valve on it like a bicycle tire. With key on, remove cover on valve and push it until fuel comes out. This may solve the problem. If not you may need to loosen the nuts at injectors to allow air to escape. Also caused by fuel line leak.
CLEAN FUEL INJECTORS.THEY ARE FLOODING THE ENGINE.WHEN YOU TURN OFF ENGINE DIRTY CLOGGED FUEL INJECTORS WILL KEEP LEAKING FUEL FLOODING ENGINE.ALSO REPLACE AIR FILTER.
Take the car in and have the fuel injector computer tested. If you're hearing the crank, you're getting good spark, but the fuel/air mix is off. Ensure your air filter is clean, and have that computer checked, all it takes is a little bit of bit-wander to make your fuel-air mix go completely haywire.
Check the fuses/relays for the fuel pump and make sure you are getting gas to the fuel injectors. Also check your fuel filter....if it is clogged it could be stopping the gas from getting to the injectors....good luck
DIRTY FUEL INJECTORS FLOODING THE ENGINE.CLEAN INJECTOR BY.FILLING UP GAS TANK. PUT A BOTTLE OF FUEL INJECTOR CLEANER IN GAS TANK.DRIVE CAR FEW MILES SO THE INJECTOR CLEANER CAN FLUSH OUT CLEAN THE INJECTORS.
check to make sure the fuel pump,injectors and fuel pressure regulator don't have any internal leaks check the fuel pressure immediatlly after it is shut off and two hours later there should be at most a very slight difference
