    I need help on a fuel pump problem. This truck will not start even if I switched the saddle tanks, I also noted that the fuel gauge seems to register at the same place. I tried changing the fuel pump relay and the problem it still the same. Checked all of the fuses and searched for any other relays that might be part of this circuit. Has anyone else have had this same problem?

    Thanks! I don't know how this works, I do know now that I have made an error when I had posted this.

    Welcome! :great: Don't worry about the 'error'; no one minds. People here are helpful and [MENTION=48263]Red Z71 Max[/MENTION] was just trying to direct you to post in a section relevant to your problem so that you would get the maximum number of page views ... from people most able to help you. Sadly I've no experience with your issue and you've already checked the things I would have checked.

    X3 on [MENTION=50075]SurrealOne[/MENTION] post. Lots of information to be gleaned from this site many many devoted and experienced individuals. hit the search engine and see if you can get a quick reply. Good Luck. The only thing I would add is check the switches themselves as I used to sell many of them.
