Q&A

Trying to figure ways to test the fuel pump gauge. It falls in front off the full icon and doesnt move at all Doesnt twitch apon start up,,,nothing. Is there a relay? Not fuse I that I know of.. Fuel pump assembly maybe or bad ground?? Im a girl just trying to be direct with my search, first time working on a van:) Also I hooked up an after market radio and it plays but gets really hot.. crossed wire huh? no static on connection of the speakers... Fuses are fine. No original harness.
