One day i went to work and my bike was just fine. then when I get off my bike first started and then died. I crank it and it fires but doesnt start. in the mil it flashes a red light and stays on when i turn the switch key on. i remember the red light would then turn on when i turn the bike on.

i change the spark plugs I change the oil i change oil filter. I cleaned the throttle body i pulled the fuel pump out and checked for any broken wires or anything bad. I pulled out the spark plugs and put them back on made sure they were tight enough and that everthing was re installed properly.



I dont know how to test it whether it is the fuel pump or anything electrical.

Anyone suggests ???

 

Moved thread, this is where you want to be if you've got F4i questions or problems.

 

how many times does the FI light flash? FI codes will tell u what to troubleshoot.

check the battery connections. maybe they got loose. check the ignition pulse wire for damage... it's the wire on the right side, coming from the clutch cover.

if you want to test for 1) fuel and 2) spark..then you can
1) pull the fuel rail... place some towels underneath the injectors (all at once)... try to start ur bike. wet spots..means fuel is pumping out

2) pull the spark plug... while in the coil... use a screw driver or something to ground the plug (1-by-1). start the bike.. if u see spark then u have fire.

 

Correction is not the F4 light is a the red light to the left of the N light

 

i pulled the fuel regulator and there was fuel coming out of it

 

Your fuel pump primes?

 

it used to now i dont hear anything at all still trying to check if it is receiving any power

 

I'm not trying to insult your intelligence or anything but I found out the hard way that the bike won't prime if it's in gear. since I'm new to motorcycles I didn't know and I killed the battery trying to start it. LOL, I won't make that mistake twice.

 

ive been trying to check if the fuel pump is receiving power anyone have some ideas beyond hearing ?

 

get a multimeter and check if there's voltage going to the fuel pump. if there's voltage at the pump and it still doesn't prime (doesn't make that eeeeeeeeee noise when you turn on the bike)...then you may have a bad pump.

if there isn't voltage...then bypass the relay....if that works..then u need a new relay.

if that still doesn't work...then u need to check all the sensors and headlight connection, and ecm
