I have a 97 Volvo Penta 7.4 ltr that isn't getting any fuel. I have found that the fuel pump isn't getting powered up when the ignition is turned on. The boat will turn over but no fuel getting out of the pump. There is a relay attached to the pump. It has power going into it from the hot lead but nothing coming from the switched lead. I can't find where the switched leads are coming from(beneath the engine somewhere). Could a starter solenoid cause the switch lead to not activate? I am at a lose. Thanks for what ever help can be supplied. Rodney
