Cant get the bike to start - can anybody please help?

The bike refused to start and was indicating F1 on the display, which turned out to be a "c41" fault (Fuel pump or relay problem).
I have tested the fuel pump relay, the one that sits to the left hand side of the ECM, and this is fine. I have removed the fuel pump from its assembly and put a 12v supply across it and it works fine.
With the fuel pump disconnected from the 4-pin connector under the seat, the F1 display disappears. As soon as I reconnect it, the fault returns on the display, even though the pump works fine when connected to a battery.
I have even tried connecting a pump that is in good working order from another bike (ZXR400) and each time the connection is made the F1 display returns.

Other things I have tried are checking connections at connectors, particularly the 4-pin one at the main fuse above the battery - this is following advise from other people who have posted problems with a c41 code on this site.

Sorry to go on a bit, but just wanted to make sure I listed everything that I have tried!

Thanks, Andy

Welcome to the site Andy:bigfinger Have you checked the 'Tip Over Switch':O i think this shows the c41 code. Is it a 'R' or a 'S' you got. If it is a R then i think the switch is at the rear of the tank. Do a search on here just to check though:thumbup :bwtiller

I belive that he is correct in assuming that it is the tip over switch fault code.

good luck

Feeling too lazy to read all the trouble shooting... My bike had that code 2 months ago and i got a new ECU... what a waste of $. The problem ended up being a broken wire in the loom btwn the ECU and relay.... $.02 of soder and i was good to go. Just something to think about. :O

I had this happen on last service, they found out it was a fuse blown located at front of bike.

Don't know what happened, they just couldn't start it after a full service.

Yahoo!! The TL is alive again!
I tried the Tip-Over switch and everything was fine and also the connections as suggested above and still couldnt locate the problem. I was about to give up and discovered a bit green "gunge" coming out of the large white connector block (left hand side of clocks). I took this off, give it a good clean and that was it! - Fault code disappeared.
It appears as though dodgy connections cause a few problems on these bikes - looking through the forum people have had various failures due to corroded connectors. I will be giving mine a regular spray of WD40 from now on!

Thanks for taking the time out to reply to my original cry for help.

Cheers, Andy
