The isn't even turning over, so I don't if it might be the ignition switch, or starter. I do have press the clutch to start this truck. Next where is the starter located on a cummins?[/size]

Even though this is an old thread , Just Incase .

99% of the trucks I have driven are Peterbilt with cats , the one I have now is a cummins.
Same starter on all of them including my freightliner.
There is a two wire plug below all your wires right at the starter motor. If you have any kind of oil leak where that plug is getting oil on it the oil eventually gets into that plug and when it does the starter won’t do anything and I mean it flat out won’t do nothing when you turn the key.

No click no power draw nothing.
Unplug that plug and spay some either or brake clean , something to cut the oil and flush out the plug”both sides of the plug”. Put the plug back in and if that’s the problem it should start. The first time this happened to me my truck was down for three days trying to figure out why it wouldn’t even try to turn over.
