What does a fuel cutoff relay do?

The relay is there to power the pump when the engine runs, and stop when the engine dies.

How does the fuel cutoff relay work on a Honda?

This will stop the fuel pump, so that gas will not be pumped onto the scene of an accident. The bike will pump fuel when the starter is cranking, and should full your carb bowls, giving you fuel to start the bike. There’s a few minutes worth of fuel stored in the carb bowls anyway, so the fuel pump doesn’t need to run right away.

What is the function of the fuel pump relay switch?

The reason I asked about the function of the fuel pump relay switch is a long story. When I ride the bike in the rain, it loses power, then stops firing then I have to slow down to an idle. If I try to throttle it up, first the rear cylinder quits, then throttling up further kils it all together.

What happens when you remove the relay switch?

So we removed the relay switch and the problem materialized before my eyes. Not similar, not kinda, but exactly what happened on the road. Backfiring, losing power, finally only able to idle, and dying when throttling up.

Why do you need a fuel pump relay?

The fuel pump relay is a safety design. The idea is that if you should crash into something, have something crash into you, or have some other sort of mishap, the engine will likely stop at the time of impact. This will stop the fuel pump, so that gas will not be pumped onto the scene of an accident.

What is fuel cut off?

A fuel cut-off device for an internal combustion engine having a fuel supply means into the engine. The device comprises a fuel cut-off means for cutting the supply of fuel to protect the engine from an abnormal rpm rate when the engine speed exceeds a fuel cut-off reference value at a relatively higher speed range.

How do I stop fuel cut?

The simple answer is that because fuel cut is pre-programmed into the ECU, there is no method of disabling it. There are no modifications that can do so, aside from an ECU upgrade that eliminates fuel cut. Upgraded fuel pumps, injectors, and fuel pressure regulators do nothing to avoid or eliminate fuel cut. NOTHING.

What is auto cut in fuel tank?

Auto cut-off is only a safety device to avoid spillage. At times just the fumes of the fuel may activate the trigger to shut down the flow to avoid spillage. You can always shake the vehicle a little and continue from where the fuel flow stopped.
