I have a 04 ion redline, I parked it a year and a half ago in storage and recently went to start it but it will not crank over, we jacked it up and checked for power on the starter solenoid trigger wire in the ign. Crank position, clutch pedal depressed there was no power present at the solenoid.
we jumpered the starter solenoid to verifiy starter operation, the starter engages and the engine cranks over ok. We found it odd there is power at the clutch pedal switch in the ignition (run) position.(Should be hot in crank position?).
we suspect the ignition switch is faulty, as the wiring integrity is good, there is no corrosion to be seen as i'm in a semi desert climate, and because this car started and drove and was parked in this location a year and a half ago.
we did not have tools with us to dissemble column and do testing at ignition switch. That is our plan for tomorrow.
this car has keyless entry but i'm not sure if there are ani-theft functions witch may be inhibiting the car from cranking over. We do not have electrical schematics.
any suggestions?

Circuit Description
Moving the ignition switch to the START position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM)/powertrain control module (PCM) requesting engine start. The ECM/PCM receives a 12-volt signal from the park/neutral position switch or clutch pedal start switch notifying that it is safe to start the engine. There is a splice on this circuit in the fuse block-underhood that supplies power for the starter relay coil. The starter relay coil control circuit is then grounded by the ECM/PCM closing the switch in the starter relay suppling 12 volts to the S terminal of the starter. Ground is supplied through the engine block
