i have a big problem

[sweetride10r]

I have a 2001 busa and for some reason the fuel pump wont shut off unless the key is off. anyone have any reason why or had this problem before. WHere is the fuel pressure regulator locatede i think it might be that.

 

[Rosco]

Fuel pump on/off condition is controlled by the EMC, the regulator and pump bypass are only for overpressure and are mechanical with no sensors to the EMC.

So sayeth the book.

I take it that when you say wont turn off you mean when the engine is off andyou first turn the key it humms happily to itself continually insted of running for only a few seconds.

Cheers
