How can i get information on starter issues. on 2000 Toyota Tundra

Some mornings it will turn over immediately other mornings it may click up to 10 times before connecting. I have three friends who all are experiencing the same issue. I am convinced it is not the starter but an electrical issue. No one can give me a good answer. Help

You are right it is an electrical issue, starter contacts worn, replace the starter motor! Or just click on.

Replace the starter. The starter is located on the intake under the plenum on the 4.7
