Symptom: Possible no start, no crank or intermittant no start and trouble code P1632.
System: Body/Chassis Electrical, Emissions/PCM/Fuel
Codes: P1632
Problem: The lock cylinder housing and the rotating lock cylinder are defective, affecting the fuel enable circuit in the computer causing the no start and trouble code P1632 to set.
Test & Fix: Access the Passlock sensor 3-wire connector, located in the ignition lock cylinder housing. Leaving the connector plugged in, check for 12 volts on the White wire and 0 volts on the Black wire. This is the power and ground provided by the Body Control Module (BCM). Disconnect the 3-wire connector and verify that the BCM is sending out a 5-volt reference on the Yellow wire. If any of these voltages are incorrect, check for a problem with the wiring or BCM. Plug the connector back in. During cranking, a resistor in the Passlock sensor will drop voltage on the Yellow wire. Verify that the voltage always drops to the same level. If not, replace the lock cylinder housing and lock cylinder. Perform the relearn procedure. NOTE: Voltage drop on the Yellow wire will be different for each vehicle as there are 10 different possible resistor values. In some cases, this problem is too intermittent to test. If that is the case, the most common cause is a defective lock cylinder housing and the rotating lock cylinder.

there is a problem with the security microchip in your ignition key, get another one (instructions for programming are in your owner's manual) or upon further investigation it may be your ignition switch that is rejecting the codes.
