Ok I live in California I'm going to fish a river at the Sequoia National Park around 3000 feet I'm looking to catch big rainbows I only have a spinning rod and I'm on a budget, I have caught fish there before but nothing over 8" I couldnt get them to bite anything but nightcrawlers and I will be leaving in a few days does anyone have any tips or tricks that can help me?

don't know the area, but i would use spinners tip with a bit of crawler. or even a small flatfish with a bit of crawler.
also check out the trout threads on this site.

get a clear bobber and an assortment of flies. leave about a 2 ft leader after the bobber and tie on your fly. this rig is great for spining rods and you catch good fish on it (well,i have caught good fish on it) good luck and tight lines

I don't know how big that river is, but I generally use spoons and inline spinners to catch larger trout.  The spoons I favor are Kastmasters, Little Cleo's, Daredevels, Syclops.  The inline spinners I favor are Rooster tails, Mepps various types, Panter Martins, Blue Fox various types.

I guess that's quite a bit of variety and it does come with a cost.  I think the most affordable and most productive ones are Kastmasters for spoons and Rooster tails for inline in my experience.

I tend to use Roostertail inline spinners for large trout. When trout become a certain size they feed mostly on fish and less on insects.
TIGHT LINES!
