2004 CBR600RR cranks but wont fire
Hi, I hope somebody here can help me out.
I had a fall at the track on Sunday on the left side, the bike slid then flipped on the dirt quite hard. I picked it up and rode back to the pits. Then tried to go home but it would not fire. The 4 wires leading from the lambda sensor on the left got severed and presumably touched eachother plus the engine cassings. This was the only visible damage apart from bodywork.
I fixed the wires at home, and they are sending a signal (power is there). Now when I turn the key to ON it lights up as usual, when I hit the start/stop button I can't hear the fuel pump priming. There are no error codes.
Ok so Ive checked the following:
First the BAS is in the correct position and fuctions properly, I can here a relay click when I turn it upside down.
All fuses in the fuse box are good and have continuity, the 2 fuses near the battery are also good. The battery is on a charger.
To rule out a relay I switched the 3 relays on the left around and that didnt help.
The start/stop switch appears good, all wires soldered on.
It has fuel.
I checked every conceivable wire connection
I checked the side stand switch.
Headlights working, indicators and tail light not connected.
I brigdged the one relay which I traced back from the fuel pump with a piece of metal. This allowed 12V to go to the fuel pump, and it then stayed priming continuously, however the bike still did not fire.
Please can anybody tell me where to look next, I am very stumped...and am starting to think it could be a sensor that is not visible ie. in the engine or fuel tank...?
BTW we think it started and ran back to the pits with whatever fuel was still pressurised in the fuel hose, without the fuel pump working.
Thanks guys, I am pretty stumped right now.
