Are you certain the tank fuel connector is connected properly? Do you hear the fuel pump run briefly when you turn the key on? Before I change a pump out, I’d want to be sure the pump is actually bad. So the first thing I would check is the fuel line connector and also the electrical connector. These things are not standard looking connectors, and if they aren’t perfectly matched and locked, they won’t connect properly.
Did you disconnect the fuel line at the tank, or at the fuel throttle bodies? The reason I ask this is that the tank connector is really hard to lock into place due to the minimum amount of room in there. I usuall disconnect the line at the throttle body and pull the line out with the tank. When I install the tank, I only have the electrical connector to fight with and I feed the fuel line in as the tank is going on. Then it’s relatively easy to hook up the fuel line to the throttle body.
Just a thought there. I take it the bike was running before you changed out the cables? Also, are you sure certain you have the cables rigged right and that the throttle body arm is against the idle stop? That’s important too. However, if there is no fuel pressure, I’d be sure to chase that down via the connectors first.
Just one more question: Where are you putting the fuel gauge to measure the pressure? At the tank, or at the throttle body?
