cbr 600 01 not cranking or fuel pump priming

[jerry gerbil]

as title says all lights work, if you jump the starter solenoid it cranks and if you put battery to fuel pump it primes relays are good at a loss ECU fried ?

Does it have HISS fitted?

[Islander]

It could be the fuel cutoff relay.

yep have checked all fuses relays are good hiss light goes out bank angle sensor checked unplugged cleaned every connector I can see no codes flashing up totally stumped

You've got it in neutral, kickstand up, and killswitch set to run? Stupid questions, but always start with the basics

yes it was running till yesterday morning yes it has Hiss yes original key yes kill switch in normal position
there is also power getting to ecu ,fuel pump relay (relays are good) and starter relay

[Pete.]

Alarm/immobiliser fitted?

On my Honda if I go to put it in gear and the stand's down it cuts out. So that's the neutral (or shift) sensor and kickstand switch it must be looking at.

Worth checking both of those switches/sensors and the associated wiring.

So now we know the basics.

The fuel pump should prime as soon as the ignition is on, this would be a combination of the key being turned on and the kill switch being turned on. Flicking the kill switch on and off a few times the pump will re-prime.

First thing to check is power is going through the kill switch. then that things like the side stand switch and the neutral switch are all working.

Other than when priming the fuel pump only gets power when the engine turns over so you need to connect a multi meter to the relay to check its getting power in and power out. Checking that there is power going to the relay will confirm if the HISS system is working, if it gets power it is, if not it isn't.

Also check there is a spark.

Should the HISS light on this model go out when the ignition is switched on and does it?

Has the chip fallen out of the key?

Is the antenna for the key chip still connected?

was the diode in ignition barrel /hiss that drops current down to 9v to ecu but just bought a zxr 900 so ill fix when I get around to it thanks for all the suggestions and advice was very helpful

[sickpup]

[jerry gerbil]

the diode in the hiss is supposed to drop the current to 9v if you look on internet about pink wire from ignition it should come up took a lot of looking but its out there

wasn't lecturing sorry I put diode instead of resistor don't worry I wont bother you anymore bye but thanks to all who tried to help
