Your reply really sucks.

SOURCE: Starter or solinoid?

I never heard of a starter solonoid coming with shims. Did you replace the starter or starter solonoid?
What engine do you have?

When you turn the key on all the lights come on normally? and when you try to start you lose the lights and hear a click? If so the battery cables are loose, or broken. If thats not the case it could be a relay or stuck starter or switch. You can try a screwdriver at the starter hit the little wire and the big wire it will spark and should turn the engine over "MAKE SURE IT IS IN PARK WITH THE BRAKE SET" do this last, if you do all that and it turns over you can say the starter and cables are good. Next replace relay and try, still nothing get a new switch. Hope this helps.

First, make sure you can turn the engine by hand. If you can't then the starter can't turn it either. Have someone else turn the key and look for the source of the click...may be a relay. Go over the starting circuit with a volt meter. Check for power at the starter main terminal and then with the key turned to "start" check for power at the trigger terminal on the starter. Check battery voltage and check relay operation.
You have a neutral safety switch on the transmission if its an automatic and a clutch switch if it's a stick. Check them as well. Make sure battery grounding on fender and block are also clean and secure.
