Check your ECM fuse. There should be 2 fuses for your ECM. It's the ECM that controls the function of the fuel pump. Good luck friend and it's also common for the wire harness from the frame to the fuel pump to go bad due to corrosion from the bad weather we get in the winter and rainy spring and fall.

you can manually actuate the relay if you want. Take the cover off, and push the contact over with a screwdriver and see if you can hear the pump. Have you checked to see if there's power to the relay, both the control side and the side providing power to the pump? There's two different circuits involved here, so you have to make sure they're both ok. If you have power before the relay, and power coming out of the relay headed to to pump, then your problem falls between the relay and the pump. Other things to consider, are the fuel pressure sensor, and oil pressure sensor. Some vehicles will not turn the pump on if they sense no oil pressure after a couple of seconds. Secondly, if the fuel pressure sensor is telling the pump that there's plenty of pressure, (even if there's not) it'll shut the pump down. Hope this helps you.

The individual LED lights are not replaceable. You will have to replace whole lense assy. Remove two screws, then unplug wiring connector. These are expensive from dealer. Shop around for a better deal. Auto stores, online sellers, and even eBay sells them.
