Pete M Posted February 19, 2018 Share Posted February 19, 2018 did this come on suddenly? any trailer light wire harness integrated out back? check the ground located inside the dr side taillight. double check that all your bulbs are correct and the sockets are in good shape. after that I would check the harness connector located behind the drivers side rear tire underneath the truck. I had corrosion inside that killed the brake lights / turn signals. Link to comment Share on other sites More sharing options...
Cmorris24 Posted February 19, 2018 Author Share Posted February 19, 2018 No idea just bought the truck. Had been eaten alive on the wiring. Ground wasn't great so I redid it and it's very good now still nothing out back all bulbs are good etc. It does have a 4 pin trailer hook up integrated somehow. My fuel pump isn't coming on as well just fyi Incase it's related. Link to comment Share on other sites More sharing options...

Keyav8r Posted February 19, 2018 Share Posted February 19, 2018 You don’t need to drop the tank to change the fuel pump. Make sure the fuel level is below the pump mounting, drop the driveshaft (to get more room to work), then remove the pump/sending unit by removing the lock ring. When you remove the lines push a bolt into it and tighten the hose clamps to stop leakage. Get a new lock ring and gasket when you re-install the pump/sending unit. This is much easier than dropping the tank, unless you need to change the vent fittings or clean the tank. Link to comment Share on other sites More sharing options...
Cmorris24 Posted February 20, 2018 Author Share Posted February 20, 2018 Pulled the pump with the tank in but found frayed wire above it I need to get to and the tank is a wreck judging by the pump. Ethanol looks to have taken it's course after 5 years silly me for having faith it's not designed that way. So gotta drop it now but thank you for the tips this seems to be a great forum! I read more than I post so thanks for not flaming on ant dumb questions I try not to post them haha Link to comment Share on other sites More sharing options...
