No fuel

[rubbersidedown]

Do you mind if I jump in on this ???!

I have a Gen 1 (2006) I have been going through some electrical issues (grounding problems) that I believe I have resolved.
When I turn the key gauges sweep but I don't hear the fuel pump reset.
1. No F1 codes
2. Fuel relay is good. (checked ohms from relay all the way to pump)

I seen a youtube on testing a GSX1000 but it has 3 wires into the fuel pump and a busa has 4 ( Ground, gas level, power, and ??)
Do you know of a way to test to see if the fuel pump is bad with a volt meter?

Thanks for letting me jump in

3 wires to the fuel pump yellow/red trace
black/white trace
black/green
Disconnect fuel pump. Find a good ground for your multi-meter.
Test for voltage at the yellow/red wire with ignition on.
Test the ground as well (you mentioned chasing bad grounds)

Rubb.

Nobody, not even a professional mechanic, is going to read the whole service manual before trying to solve an issue. Be for real.

a (wherever) newbie should read first and all and till the end

And like I told him, owners manual and service manual are two different things.

I'm one of those nuts who read the manuals-both service and owners.....great thing to do during the cold winter months.
