02 1800 R fuel pump not coming on when the key is turned on. do fuel pumps just suddenly quit or is there usually some kind of warning that they are going bad ? How hard is it change the fuel pump and are there any tricks that would help make it easier..... Should I go with a OEM fuel pump or is there better choices ?? Any info on this subject will be helpful thanks.

Do you have a fuel manager on the bike?
Does it have power? No power to the fuel manager = no fuel pump.

Fuel pumps will just quit. The one in your bike could be almost 20 years old. OEM is it if you want ease of plug and play. If you want options, go to the "How To;Step-by-Step" board for how to go with a substitute

no fuel mgr. on bike. it is the original fuel pump. I've had the bike since 04 . does the engine/stop switch (kill switch) relay control fuel pump ? and if so is there a easy way to check it.???

The ignition key does not control the pump.
The engine run/stop switch does. When you turn the engine switch to the run position, the pump should prime for a second or two.

Hans will be by shortly with the proper diagnostic procedure and plethora of expert information.

When was the last time it was running???

Have a test light or a voltmeter???

IGN switch + Kill switch is the positive trigger for the Engine Stop Relay.

Bank angle sensor is the negative trigger for The Engine Stop Relay.

Red/White wire is +12 volts from Bat + to 30 amp fuse to the Engine Stop Relay.

Black/White wire feeds +12v to ECM, Ign coils, Injectors when Engine Stop Relay energized...

Test and analyze..

Hans : thanks for the info. I now have a place to start . rather then just going to the fuel pump and replacing it. which may not be the problem. thanks.

thanks to all for the help. a special thanks to Hans & Feet. it turned out to be the engine stop relay. got a chance to change it out today and the fuel pump came on and the bike fired right up , just like it has for the past 17yrs. much better and cheaper then replacing the fuel pump. Thanks again .
