soon after, i hear a click, then the gauges go back down. also, starter may be going out, i couldn't be sure before the battery went dead, but it was turning over the fan, so..... truck ran fine last week, been in garage for the week, now no crank. only thing i've done lately was change pcv valve, replace rear u joint and an oil change last weekend. please help.

 

Gauges sweeping is usually a sign of a weak battery. Probably time for a new one.

My gauges did the same thing for about a week before my battery was toast.
funny thing was it would still start what seemed normal with the funny gauges. i put the new battery huge difference i guess i was just used to the slightly slower cranking.
