Swap the relay with another, such as AC compressor relay. Rent a fuel pressure tester kit from the parts store, which is free when you return it.

Define wont start please. Does the truck crank? Or does it do nothing at all. If nothing I'd be checking battery and starter as well.

Do the gauges show anything with the key on? Volt gauge should show battery voltage at least.

You have a failed sensor somewhere. Check and see if you are getting spark.
