I have an '02 Speed Triple that has been a source of a lot of frustration since I bought it about 2 years ago. Everything was ok at first, and then it started quitting on me without any pattern. I'd be riding, and it would just stop. Sometimes I'll have been riding all day, sometimes just a few miles.
When it quits, the engine just cuts out without warning. Dash lights are still active. Then it will crank but not start. I can crank it until the battery dies and it just won't go.
I replaced the wiring harness last fall, and it ran solid for 8 months. I thought I'd solved it. Then it quit on me last weekend 500 miles from home, same problem.
When I got home, I swapped ECU's, and it didn't start. I swapped a fuel tank from another Triumph, and it started. I switched back to the original tank, and it started. I switched back to the original ECU, and it started. So, in original (non-starting) configuration, it started with nothing more than temporarily moving some parts around.
Each time it dies, I get these errors from the ECU:
0463 - Fuel level sensor above max voltage
0230 - Fuel pump relay fault
1231 - Fuel pump relay open circuit
0113 - Intake air temp sensor too low
These errors can be reproduced by disconnecting the fuel pump connector (0230 / 1231), fuel level sensor (0463), or air temp sensor (0113) while running. However, I cannot do anything that makes all 4 errors appear at once. From the wiring diagram, I can't see any circuit that includes all of these components.
Side note - when pulling the fuel pump connector while the bike was running, the way it quit (running out of fuel) was somewhat similar to when I was riding it. However, I can't say for 100% sure that it is identical, since this was a test in my garage, not while riding.
Now, there is no fuel pump relay on the '02. But, I've checked all the relays and replaced any that were suspect. Fuses are all good.
During this 2 year process, I've replaced the whole wiring harness, cleaned every connector, and used dielectric grease at every non-gasketed connection. I've replaced the battery, ECU, fuel filter, fuel fittings, and checked the fuel pressure. I've replaced the fuel pressure regulator, and checked the vent lines.
The only thing that semi-reliably makes the bike start again when it quits is removing the tank and putting it back on the bike. I’ve had this happen more than once.
The fuel pump is about the only thing left that I can think of that could be replaced. Can a fuel pump fail intermittently as I've described? If so, why would removing the tank and putting it back together let it start up again, even if it was only for a short while?
Any advice is greatly appreciated.
