First of all make sure the battery is fully charged and the connections are tight. Grab the battery cable terminals with your hand and try to turn them, if you can turn them by hand they are too loose, tighten them.
Next, with the key on start check for voltage at the purple wire at the starter solenoid. Also, make sure you have battery voltage present at the big red cable on the starter and the starter bolts are tight. Grab the starter and try to move it, if you can move it tighten the bolts.
If no power to purple wire with key on start check for voltage at the purple wire coming out of the start relay 62 in the fuse block underhood.
If no voltage there check the start fuse #43 30A in the fuse block underhood.
If fuse good and still no voltage at purple wire, check Ign Fuse #23 15A in the fuse block underhood.
Let me know what you get so far and we will go from there.

heavy_chevy_396, Thanks for your reply to my question. I've been told by another mechanic that it is my starter. Hard for me to believe starter has gone out on 2005 with approx. 45,000 miles. Having it towed to dealership this morning & will suggest they check fuses before performing starter replacement ($800.00!!!).
Happy Holidays to you & thanks again for your input.
Autozone has a starter for $185.

It cannot take more than 1 hour to replace a starter, at an average of $65 an hour, that only comes to $250. Donot let them rip you off. Exspecially if it is only the starter solenoid that is bad.
Here is a rebuilt starter for $107.
I used to rebuild starters way back in 1984, and my boss charged a flast rate fee of $35 no matter what it needed, although most of the time it was a either $4 brushes, $2 bearings or a $7 solenoid. Check the yellow pages for automotive electrical shops, they can probably rebuild that for cheaper.
Even if you have a advanceauto, napa, autozone, etc near you check the prices. Come straight out and tell that dealership you refuse to pay 100% or more markup prices on parts. Ask them if you can supply your own starter. Plus, ask for the old starter back and take it into the autoparts store where you bought the new starter for the core charge back and also have them test that starter for free and see if it was actually the starter or just the solenoid that was bad or who knows, maybe it was just a fuse.
I'm sorry $800 just sounds ridiculous to me.
