2003 cbr 600 f4i No spark No fuel.

In need of help or any suggestions on what I could possibly do to get my bike up and running.

I have a 2003 cbr 600 f4i that I recently bought from someone bike wouldn't start due to it not getting any spark to the plug wires and the fuel pump isn't priming I've check all my grounds,relays, cut of switch etc still nothing purchased a brand new ecm box plugged it up and still the same thing no spark and no fuel. Any suggestions on what it could possibly be

 

Does the headlight work? Did you check the bank angle sensor? Did you check the fuses? Did you check the harness for damage?

 

Yes head light does work they completely done away with the tilt sensor must of trash it have one on order for the bike they also have it bypassed. check all the fuses they where all good, had to buy a key switch as well, the wiring harness did have a split wire spliced it back together with a wire connector.

 

Where did you get the key switch from?

 

Ebay

 

That could be part of your problem. Ebay ignition switches are notorious for not having the diode to drop the pink wire voltage to 9v.

I assume this is a US bike.

 

Yea its a US bike I've had a lot of people tell me about the diode how would I check to see if it has one. If it doesn't have a diode what type of diode would I have to buy

 

Look at the switch where the wires are on it. There should be a diode on it where the pink wire attaches. There needs to be 9v on the pink wire. That's what the diode does.

 

There was no diode in the ignition switch. I hooked up a 9v battery and got my bike started. what kind of diode would I have to buy to fix it to where I wouldnt have to keep using the 9v battery to get it started?

 

I have no idea. I would get a good switch and be done. But if you want to install a diode in the circuit, I have seen the specs on the one that works in a thread or two.
