An important element of the power program that receives a sign through the PCM to switch on the fuel pump motor may be the gas pump relay. Make sure you check out continuity between the relay’s terminals as you may inspect it. Switch out the relay with a new one if there is no continuity.
Hook up terminal 86 to the positive ( ) terminal from the battery to evaluate the communicate. Then, check out terminals 30 and 87 having a multimeter.

Typically, a negative sender or soil relationship near to the tank will be the basic of energy gauge troubles. You can also examine the fuse and the wiring connections if the issue is electrical. The less than-dash connect or maybe the tail light control plug is where the delivering system is associated.
Before you start examining the electrical connection, make sure the ignition switch is switched on. Validate that this pink wire is grounded to the chassis ground and that the fuse is in good shape.
