Went to start my truck the other day and it buzzed under the hood when i turn the key to start. after i turned the key off then back on I have no power to the starter fuel pump or gauge cluster. What happened? Ive check the battery and all is well the alternator was working before this. swapped relays around and no change.

does anyone have a diagram for the main ground locations? Ive looked and can only find a list but there is some differences between models and years.
