CBR1000rr 2004 cranks but wont start. Fuel priming
 

BAS/TIP sensor problem would disable entire EFI system since it's directly connected to ground-leg of engine-stop relay.

Relays do go bad though, so swap fuel-pump relay with one of others and see if it works.


EDIT: BAS provides ground to engine-stop relay, not fuel-pump relay.

Fuel pump is priming so TIP sensor is ok? I think
 

I thought that but the fuel pump runs. It primes everytime I toggle the kill switch to run so I know the BAS/TIP sensor is fine. Something is stopping the injectors from getting power and injecting. It is driving me crazy. I removed the ecm (as if I could do something with it anyway), thinking maybe I could see something and when I disconnect the wiring looms. There is something in one of the connectors that looks like filings or bits of something. I'll attach photo. No idea if it is anything.

ECU is what triggers fuel-pump relay. So at least those 3 parts are OK.

Speaking of ECU, jumper the DLC connector to get ECU to flash error codes. It might know something's wrong with system.

Also measure for voltage at injector and coil connectors with key ON

Excellent. I will try thank you. I will let you know.

Forgot to uoload photo. There are buts of dirt or plastic shavings at bottom of connector dont know where from seeing as ecm sits upside down.

I haven't had a chance to work on bike yet but I will tonight I hope. I will start from the beginning and retest everything

So new update, still not starting however I started again with my testing
I have spark, I have working side stand, I have working neutral switch, I have reset TIP/BAS sensor, I have pulled the kill switch apart although I know it is working because when I turn it on with the key on, the fuel pump primes and when I turn it off the fuel pump stops priming.I have put fuel in it, I have fuel pump priming and fuel at the secondary injector rail. I have charged battery. I don't have start. I haven't got a tool to test pulses on the injectors but I feel something is stopping the injectors from working. If I unplug 1x injector the bike won't even crank but if they are all connected the bike cranks but doesn't even think about coughing or firing/turning over.

I spray start ya bastard (starter spray straight into trumpets and it starts and runs happy until it runs out of spray. I have checked the 2x fuses near the battery, and all the fuses up the front left. I know it is something ridiculous but for the life of me I can't work it out. I feel without a cable to test the ECU I will have to send the bike in to the shop (which pisses me off because I thought I was better than that).

Any final suggestions anyone before I give up and put it on a trailer to the shop?

Thank you

This is great troubleshooting! Very odd as injector circuit doesn't have anything to do with starter. Lemme look at wiring diagram and see if some kind of short from starter might knock out injector.

Any non-stock wiring or electrical mods?

Ok great thank you. Indicators have been changed to LED but was running happily. I was trying to work out what stops the injectors getting their pulse. Only thing I can think of is the ECU. I was under the impression that everything else sensor or switch wise cuts the fuel pump not the injectors or spark. Thank you for thinking about it.
