Hello, thank you for writing in. With the testing you have done, we know the fuel pump is good, and that the rest of the system is functional. This leave the electrical circuit. There are a few components in the fuel pump circuit which could be causing the issue. The first to check is the fuel pump fuse/relay. If you have a voltmeter, you can trace the power from the battery to the fuse box, and along the circuit until you find the point in which power is lost. This is the fastest way to pinpoint the exact location of the problem. A visual inspection may also show you if there is a loose or disconnected wire, or excess corrosion somewhere causing extra resistance. For more help tracing down the issue, contact our service department to schedule an appointment.
