Title: Fuel pump relay
Post by: Suzuki boi on Monday, 25 March 2019, 10:11 PM

So I've had an issue the past day of the bike not starting.
CHEC was on the display.
Had a look at the fuses.
The 15amp ignition fuse was blown,changed it thinking happy days .
Nope blew as soon as I turned the ignition.
So fault finding began :facepalm:
Opened headlight disconnected all connectors turned ignition on and plugged in one by one till it popped.
Found the culprit.
Managed to narrow it down to the fuel pump.
Disconnected fuel pump, turned ignition ,no pop.
Plugged it back in,no pop. Attempted to start.
Nope,feels like it wants to start but doesn't.
Sounds like the pump gets 12v for a split second then nothing
Stripped the fuel pump down ,tested it all good.
Reconnected and noticed the relay is now constantly clicking and CHEC is back on.
So fuel pump relay seems the issue but I can not find one online or locally.
Anyone know of any kind of by pass or if another bikes relay fits it? Bandit,busa?
