Question about 2000 Cadillac Seville
The switch can be tested with a multi-meter to see if it is the problem. The switch will have a hot at all times wire going into it. If the switch has power out on the start wire with key held in crank, or if there is continuity between the power in wire terminal and the start wire terminal (on the switch side of harness connector) when the key is held in crank, then the switch is good. Check the neutral safety switch, then the starter relay, then the starter solenoid for a fault. You may need to see a wiring diagram to find the color of the start wire coming out of the switch. A single wire from switch to the neutral safety switch and on to the starter solenoid.

It could be a loose wire or connector, defective or dirty contacts in
the lock cylinder, broken wire coming from the lock cylinder or a
temperature sensitive module to name a few things.
If this happens only when the temperature is cold, it could be a leaking Fuel Pressure Regulator (FPR), or due to lost pressure in the fuel lines due to cold, in which case you may have to replace the fuel pump / fuel filter / clean injectors.
The best way to diagnose this is to actually take it to a mechanic and have him check for you.
Hope that helps! Should you have any further questions, please post them here.

SOURCE: The car will not start.
My 2004 CTS started doing the same thing last week (October 24) Took it to the dealer the PCM was shot. It was covered under the factory warranty (130 000km if I remember right) works great now.

First off OBD 2 system which is in your car.will operate in closed situation which means although car may not run properly it will crank over and start as long as spark, fuel and air are present...What I suggest is to first check the voltage of battery..( It sounds like you have already ruled this out)If batterry has checked out good the next step I would do is check your fuses (there is a fuse for the ignition,this is probably blown....) If that checks out ok check the cable that goes from battery to starter making sure connections are tight...If all apears ok I would hook up a remote starter switch to starter followoing mfrs instruction and see if your vehicle cranks....If it does place the vehicle in neutral and try to start normally .. if it starts in neutral or any other gear it is your neutral safety switch.... I would actually try this first because it is a much easier procedure...I hope this fixxes your problem....Good luck!!!

The ignition switch is not the part with the key. it is a series of connections that are lower on the steering column.
