ok so i bought the bike the guy said the fuel pump was bad so i get it home tore the fairings off and buoght a used fuel pump when it came in i when to working on it and there is no power that i can tell going to the pump nor the relay for the fuel pump so where should i start every thing is pluged in far as i can see the guy i bought it from said it quite what he was riding it so idk ?? i took the head light and all that off but not the tach or anything why am i not geting power im thinking it is the computer i found the brown and silver wire that goes to the fuel pump on the computer and it dont have no power ether unless something is not telling it to turn on what could make it not send power please help!!!!!!!!!!!!!!!!!!!

 

Start at ur bank angle sensor and fuse box. make sure ur bank angle sensor is not installed bakcwards....

 

how would i test the BAS to see if it is bad??? thanks

 

bypass it....somebody on here has more details but u just gotta put a jumper wire in there. id have to look at the schematics to tell u exactly where to jump it......


u got 3 wires coming off the bas: green, white, and red/white... obviously the green is ground so jump the white and red/white but if im wrong somebody please correct me....

 

on my f4i the wires on the outside are connected and its the red and green

 

ok so i been working on trying to figure this out for the last week and more and i just dont no there is no power to the fuel pump or the headlights and no power to the relay by the ecm and i tryed to jump the two prong connector to get a code and it dont work or im doing something wrong but with it not giving me a code i think the ecm is bad what yall think is there a way i can check that?? and the pink wire from the ket switch is not hot if i jump it it is but it still dont make nuthing come on idk im about to just take it in to honda i guess( so they can tell me the ecm is bad lol

 

Hey just wondering if you ever found out what the cause of this problem was? My buddies bike started doing the same thing last night. He rode to get something to eat but when we came back out his bike would crank over but wouldn't stay running. We notices that the headlight, blinkers, and gauge lights were not working and more importantly the fuel pump wasn't turning on. Sounds like the same problem your having. Just wondering if you found the problem. Thanks

 

no waiting for the emc that i bought to come in that is the only thing i can think of cuz there id no power going in or coming out of it so i have checked every d@mn plug and wire more then 5 times lol so i guess it is the computer so it should be here tomarrow, everyone is saying to check the blue plug on the side of the bike that is probly what it is i got my headlights to come on just no fuel pump now they cam on after i took ever connector apart and checked it but still no fule pump so check the big blue and grey connectore that have like 40 wires in each one the blue one melts down sometimes
