No spark, no fuel pump prime and no 12v to the black/white wire on the grey ECM connector SIXTH GEN

Hey this is my first post in this forum so sorry if I formatted this incorrectly. I bought a stolen recovery sixth gen VFR (2003) with the stated issues. I thought it was a relay issue because it was missing all of them, new relays didn't fix it. Some weird thing going on with the headlight sub harness (cut up and the relay plugs missing), so I "rewired" it and that didn't fix it. weird stuff going on with the FI light, so I thought maybe it was the ECM and picked one up for dirt cheap. That did stop the FI light stuff, but the bike still has the same status of no spark no fuel prime. My original pump was bad, but I know the new one is good. Does anybody know what could be causing the lack of 12vs to the black/white wire on ECM plug and if I missed something? already bypassed BAS and it looks like the ground recall was already done on this bike the green earth wire is not adjacent on the sub harness side of the blue connector.

 

Also not sure if this is relevant or not but the FI light switches on and off with the killswitch, and the FI light is constantly on whether you have the dealer check plug shorted or if it's turning over the light is consistent.

 

its possibly risky, buy who knows ?

if that b/w wire is normally energized, you could try putting a 12v + wire from the battery to that terminal, see what haqppens.


check all the grounds u can find for corrosion or lose bolt.

 

Yeah I thought about the power but I don't wanna fry my ECU if I'm wrong and it's not supposed to have 12v. How many grounds do these have wanna make sure I haven't missed any.

 

+12 is all through the system, never stepped down to lower. show the wiring schematic to someone who can read it, then ask ?????s.

post it up here for info 411.

i believe the sugestion above would not damage the ecu, but it might get you running, and there are fuses.

unfortunately, we lost our #1 electrick expert, grum.

 

And a great loss he was too.

 

Yeah I had seen the alot of his posts, one of them is why I thought that wire needed 12v. I learned alot about these bikes going through his responses and trying things out. Weird question, but If somebody has a sixth gen could they send me a picture of the ESR relay plug with the wires? Mines is cut at the plug and I'm not a hundred percent sure I connected them back correctly.
