Just replaced ignition switch and it still wont start. Any ideas? Switch felt like it was broke. Took off old switch and put it back on and it was able to start to get home. Went to replace it with new one and it still dosent start.

Could be the ignition switch was damaged in failed attempt to possibly steal the car. U might just have to replace that switch.

Probably the rod in the steering column has failed.

took mine to dealer. Found out it was the ignition switch in the steering column. Not the lock cylinder. Dealer recomended replacing switch, but i took the cover off bottom of column and found a loose wire. Plugged it in and havent had any more iiisues. Hope this helps

There is a plastic piece that goes between key switch and ignition switch that might be broke have the same issue and trying to find out how to replace this piece.

your going to need to replace the igniton or the electrical switch part in the back of switch may have broke apart and jammed it,take it apart and seeif the key turns once the switch part is off the key part,(electric ignition switch is removed from the cylinder lock).

the ignition switch is located under the dash at the bottom of the steering column.suspect a fault in the linkage connecting tumbler to switch.

try to get a jump from a friend and see what happens, does the same, faulty starter, may need replacing, try to use small hammer and tap lightly on the starter couple time and have a friend start the car while you tap lightly on it. check ignition switch where you stick the key in. stick the key in the ignition and turn the key back and forth jiggle and wiggle it and see if your igniting will make contact. do it several time to test and see if its the ignition problems, this part is not cheap to replace.

It may be the 'actuator'. It is a rod that connects the lock cylinder to the ignition switch on the tilt wheel units. It is made of aluminum and often breaks as things become worn.

Not an exact solution, but perhaps information that might lead to one.

1.Replaced the tumblers? I believe I would replace the entire ignition switch this time. It's my belief that the body of the ignition switch is worn inside, and will keep damaging the tumblers.

2.Do you have a tilt steering wheel? It's best to keep the steering column in straight line when starting the car, then tilt the wheel to where you want, after the car is started. When the steering column is in a tilted position, it puts undue strain on the ignition key switch, and the mechanism the ignition key switch operates, on GM vehicles.

This mechanism, consists of a half moon gear on the ignition key switch, that turns inside a 'Planetary' gear. I used the term 'Planetary', as the gear shape is hard to describe. It resembles an oblong loop, shaped like the number 9, with gear teeth on the inside bottom of the loop. This 'Loop' rotates, when the gear teeth of the ignition key switch, engage the teeth on the loop, and pushes a rod, or retracts the rod. The rod goes down the side of your steering column, and turns on, or turns off an ignition switch, located at the bottom left side of the steering column.

Having the steering wheel tilted, puts a strain on the ignition key switch internals, the oblong loop can break, and/or gear teeth can be stripped off.

faulty ignition relay staying stuck on and not opening when there is no power from the ignition switch
