No power to high pressure fuel pump
Have a 2004 115 hp EFi that has no power to the high pressure fuel pump. Can hear the main relay click. New one and original relay click when key is turn on. Book says that pump should run for two seconds when key is turned on. I get nothing at pump.
My question is, is that controlled by the ECM? ? Is it bad? Can't find any kind of fuse for it.
Thanks for any help!

Turning the key to the on position should prime the fuel rail. Fuel pump runs for about two seconds. Sometimes difficult to hear. If fuel pumps does not work then engine will not start.
The ECU controls the fuel pump prime. This is done thru a relay. Do the test for a bad relay. Swap a good one in and check.
