(finally had time to do these check. apologies for the late response) 1. the fuel pump runs when the plug is bridged. does not run with relay plugged in. 2. the fuel lines and plugs for the airbox are the only things unplugged during testing. (sorry if that was confusing) 3. black/brown wire has good continuity from FCR to ECM plug. 4. i had tried this test before but went ahead and tried it again. no FI light illumination. 5. the ECM seems to be in good shape. has a few scratches and dings but the connectors look good. no cracks. (i’ll add a picture) 6. i was unable to check the ignition switch as of right now. the bolts holding it on are stripped out so i will have to drill it out. if that is vital i will remove it to check. 7. curiously i do not get 12v at FCR plug at ignition on.. i had checked it before and swore i had 11v continuously but i just double checked and i had MV… 😭

Very tricky! With (mostly) everything plugged in, the fuel pump runs continuously with the plug bridged. (didn’t hook up fuel line since it was just a test for the pump. could be why it’s running continuously. not sure.) I swapped the hi beam relay in AFTER confirmation of fuel pump. Pump did not run with relay in. Continuity check on FI light wire was good. So far everything seems good. Unless there’s a vital piece that i’m missing… I can’t help but think ECU…

You’re correct it is a non-abs bike. Yes sir I have 12v at the FCR and ESR. (also I apologize for the late response. I promise i’m not giving up just been very busy) ECU: Tested 12v on the black/white wire. Both green/pink wires tested 0.1 ohms as well as the green wire. Fuel pump: It runs! The first sign of life. I bridged the black/white wire to the brown wire and the fuel pump primed. Also checked the grounds points you pointed out and they are solid. No corrosion.

Nice idea. I just tried it and still have no spark. 😕

Okay, 30a main fuse-12v, red/white wire on blue connector-12v in/out, ESR-12v throughout and FCR also 12v. instrument cluster seems to be in good condition besides a crack in the cover and the plug is fine and wires are in order. BUT I have just realized the ABS and FI do not come on when the ignition is on.. I also unplugged some vital sensors to try and induce an FI light with no response. No idea what that means.

The legend himself responded! I’ve spent many hours reading on this forum and have seen your knowledge so I was hoping to see you respond lol. I will check everything you have suggested when I get home from work and will check back in. Thanks!

I have a 2007 VFR800 that was given to me as a project. It was a great running bike but was laid down and no longer runs. The front end is toast but I have an idea for that. My main goal is to get the bike running again. The bike cranks over strong but I have no fuel prime, no spark, and no FI light. I suspected the ECU but have been told that is unlikely. All fuses are good and all connections have been checked as well. I am hopeful that someone with more experience with this platform can point me in the right direction. thanks, Kyle
