Starter solenoid, typical position for Fomoco cars.
The starter on a 2005 Cobalt is typically located on the front of the engine, near the bottom. It is attached to the transmission bell housing and the engine block. To access the starter, you may need to remove some components, such as the air intake or battery.
First make sure that this battery has a charge. Check its volts. Then if the battery is good, make sure the conectionns are clean. Then clean the connection to the starter relay ( solenoid ) just beside the battery. Then if needed, clean the conx. at the starter. If all the conx. are good, and still no start, jump the positive battery conx. at the starter relay to one of the small plug in conx. If the starter engages, then possible bad ign. switch. Hope something works. Good luck.
GM usually uses a combination solenoid/switch/relay located beside the starter. One end engages the starter. The other end connects the battery to the starter motor.

It is normally attached to one of the 15 mm head bolts holding the ac compressor bracket or the equivalent on the passenger side of the engine. The smaller wire usually attaches to the body either at the deck lid hinge or directly to the sheet metal beside the battery.
