    I have the same problem with my 97 GMC Jimmy. I tried turning the steering wheel to that "just right" spot but nada. In searching the web I've been advised that it is probably the solinoid under the plastic cover of the steering column, or could be a switch in the column. I am trying to find out what this all looks like and where do I get replacement parts.

    My GMC dealer just tried to tell me it's because my battery is getting old and my contacts are corroded. :-(

My 2002 envoy did not start everything appears to be dead. Ichecked the battery, which was fully charged. I slammed the hood down. Lights went on car started. An hour later while idling it died repeated the slam and again started. Went to dealer. He told me to replace the ignition switch cost $54.00 part $135.00 labour. I asked him will that fix the problem. He replied it is a start. At the same time they cleaned up the throttle plate cost $150.00. From reading the problems with other Envoys they may have found the problems. At least this website did confirm that the issues are common and the dealer is on the right track. Not cheap mind u, but cheaper than buying a new one. We will see.

I've found that the steering lock on some vehicles will interfere with the ignition lock and the steering wheel may have to be rocked to find the right position.
I think the purpose of this was to ensure that the steering lock is engaged before you can take the key out; don't ask me why - if the key is out and anyone tries to steal the car, the steering wheel will find the pin the first time the wheel is turned 90-180 degrees anyhow.

What make vehicle ? Most all vehicles have a safety system .Don't try an force anything you'll break it !
Electronic Park Lock (EPL)/Ignition Lock Cylinder Control Actuator: If the vehicle is equipped with automatic transmission and a floor mounted console gear shift, it has an ignition lock cylinder control actuator system in the steering column. The ignition lock cylinder control actuator purpose is to prevent the ignition key from being turned to the OFF position when the transmission is in any position other than PARK and the vehicle may still be moving. The column ignition lock system consists of an ignition lock cylinder control actuator, and a park position switch that is located in the automatic transmission shift lock control switch. The ignition lock cylinder control actuator contains a pin that is spring loaded to mechanically prevent the ignition key cylinder from being turned to the lock position when the vehicle transmission is not in the PARK position. If vehicle power is lost, and/or the transmission is not in the PARK position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column. They also have this on column mounted shifters !

Linear Shift Assembly: If the vehicle is equipped with a column mounted gear shift, it has a linear shift assembly on the steering column. The linear shift assembly has a cable that runs from the linear shift assembly to the ignition lock cylinder case.

The linear shift assembly cable contains a pin that is spring loaded to mechanically prevent the ignition key cylinder from being turned to the lock position when the vehicle transmission is not in the PARK position.

Your best bet is to take it to a ASE certified repair shop or the dealer ! The fix involves taking the steering column apart an or the floor shifter assembly ! Also electrical test to determine what is the problem !

Ignition switch would start but would not lock into position (RUN) and would shut off and then ignition completely locked down and will not move


The ignition key cylinder in a Buick unlocks the ignition and allows the Buick's engine to start. The cylinder contains a switch on the end of it (inside the cylinder) that sends an electric signal to the starter motor. When the ignition key cylinder fails, the Buick won't start. When this happens, you'll need a new ignition cylinder. Purchase replacement cylinders from Buick.
Difficulty: Moderately Easy
Things You'll Need:

  • Ignition key
  • Punch pin
  • Cross-point screwdriver
  1. 1 Remove the screws on the bottom of the steering column on your Buick. These screws hold the steering column cover on. You may need to tilt the steering wheel to its highest position to access these screws.
  2. 2 Turn the ignition key to the "II" position in the ignition cylinder.
  3. 3 Slide the punch pin into the access slot on the bottom of the ignition cylinder.
  4. 4 Push the pin all the way into the access slot while you pull the ignition cylinder out of the steering column.
  5. 5 Insert the new ignition cylinder into the steering column with the key in the "II" position on the cylinder.
  6. 6 Push the cylinder into the column until it "clicks," indicating that it is locked into the column.
  7. 7 Turn the ignition key to the "Off" position.

I can't pull out the key it seem that the car locked the key and i cant start the car


Make sure the gear selector is fully in park, alot of times if the cars wheel was turned when the vehicle is parked the steering wheel is locked in the turn position and it puts pressure on the ignition switch. Try turning the steering wheel slightly left/right and see if it kicks back. If it does you have tension on the ignition and need to hold it until the key is turned to the on position and it unlocks the ignition. If you can try to let the wheel come to a rest before turning off the ignition as opposed to holding the wheel turned and shutting off the ignition, this will avoid a locked wheel/column

the ignition switch is an electrical part. The lock cylinder is whre the key goes and it activates the ignition switch. If you pulled the lock cylinder out, you could operate the car with a screwdriver.
Either you have damaged the ignition switch where the lock cylinder goes into it, or the lock cylinder is damaged where it fits into the ignition switch.

Section 11-05: Steering Column Switches 1996 Taurus, Sable Workshop Manual
DESCRIPTION AND OPERATION Ignition Switch The ignition switch (11572), which is mounted on the steering actuator housing (3F723), operates in the following manner:
  • The ignition switch is cycled through rotation of the ignition switch lock cylinder (11582) through a pin which is part of the ignition switch.
  • The ignition switch lock cylinder also controls the mechanism which provides a positive lock for the transaxle linkage and the steering system.
  • The locking mechanism is located in the steering column housing.
The ignition switch lock cylinder positions are:
  • ACC
  • LOCK
  • OFF
  • RUN
  • START
The key can be removed from the ignition switch lock cylinder with the column-shift transaxle only when the shift lever is in PARK position and the key is in LOCK position.
  • The ACC position operates while the steering and transaxle remain locked.
  • The engine shuts off when the key is turned to the OFF position without locking the steering or transaxle.
Blade Type
The ignition switch has blade-type terminals that engage with one multiple connector. The multiple connector is secured to the ignition switch by an integral connector fastener.
