SUZUKI GSX1300RX(11/1999 MODEL) CODE 41( FUEL PUMP/ RELAY) NO GO

The fuel pump relay is ecm controlled, (ecm turns it on when key on, starter depressed, and when engine is running) if its turning on with a jumper wire, u may need to replace the ecm.

Change the fuel pressure redulator and set it to 43 lbs.

If this code c41 comes on the problem is not your fuel pump, the FI light will not flash if the pump goes bad. The computer does not know if the fuel pump is on or off. generally the problem is in the fuel pump relay, the ecm, or a blown fuse. the hayabusa is good for some corroding on some of the connectors. check the fuel pump relay connector located under the front seat of the bike right behind where the tail section starts. You may have to take the tail section off to do so. Also check the connecter on the ecm for corrosion. If corrosion is there use CRC electrical connection cleaner and a small pick to clean it out. And then there is the fuse box located directly under the clutch lever, you will have to pull the left fairing for this. the box is under the black ram air cover. check the fuse it is a 10 amp mini fuse. the fuse in the box is at the bottom right second one up. most times it is either the fuse or the relay being bad. MAKE SURE YOU DISCONNECT THE BATTERY BEFORE YOU DO ANY OF THIS!
