Push brake pedal hard & crank steering wheel back & other way, while trying to turn key. Try to avoid leaving wheels turned when parking if it works. I always center mine then shut it off.

2002 chevy trailblazer and it will not crank or start and the key has gotten stuck in the ignition. I also got a jumpstart and it still didn't start. What is wrong, Please?


Could be a number of thing's , can you do automotive electrical testing ? Do you know if starting is PCM / ECM controlled or BCM controlled ? Do you know what these are ? BCM - body control module , PCM/ECM - engine computer !
Moving the ignition switch to the START position sends a 12-volt signal to the engine control module (ECM)/powertrain control module (PCM) Crank Request circuit. The ECM/PCM verifies that the transmission is in the PARK or NEUTRAL position. With the transmission in Park, voltage flows through the Park/Neutral position switch and feeds the starter relay coil. The PCM then grounds the control circuit of the starter relay. When the starter relay is energized it allows battery positive voltage to the starter solenoid S terminal. On some vehicles the starter will continue to crank the engine with the key released until it starts or the crank command has timed out to prevent excessive heat build up in the starter circuitry or the ECM/PCM receives an engine run flag.
Circuit Description (BCM Controlled)
Moving the ignition to the START position signals the body control module (BCM) that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the powertrain control module (PCM) requesting engine start. The BCM also energizes the RUN/CRANK RELAY. When the RUN/CRANK RELAY switch side closes, and the vehicle is in Park or Neutral or with the clutch is fully depressed, if equipped, supplies voltage to the starter relay coil. The PCM verifies the transmission is in Park or Neutral and the clutch is fully depressed, if equipped. The PCM will then ground the control circuit of the starter relay, closing the switch supplying voltage to the starter solenoid. On some vehicles the starter will continue to crank the engine with the key released until it starts of the crank command has timed out to prevent excessive heat build up in the starter circuitry or the PCM receives an engine run flag.
Do you know what a park neutral safety switch is ? What do you mean key stuck in ignition ? Can't turn the key to off position , or you can an the key will not come out ?
Your best bet , take it to a qualified repair shop .

Problem with 2003 trailblazer. The key ignition has been wearing out for a couple years now. We would have to move it up and down ect.. Then it would eventually start after 5 mins or so. Mostly during the...


I am wondering why when the key and probably the cylinder is worn you changed the ignition switch?

Your car is young enough to have an immobiliser as standard, probably a passive type with a coded transponder in the key. Perhaps it is that causing the trouble.

Coincidence is possible so verify the starter is still functioning by energising the solenoid at the starter if it is accessible. If the engine cranks and starts all is well. If it cranks and doesn't start then the immobiliser is a possible cause. If it doesn't crank the starter could be faulty.

If it cranks and starts I advise going back to the ignition switch and energising the starter from there by bridging a live wire to the starter wire. If it doesn't crank it is either a wiring fault or the immobliser if it has one. If it does crank and start the fault is likely wear in the part of the steering lock that drives the ignition switch.

Good luck!

Will srart by the starter but not by the ignition and won't stay started


First let's define some terminology. The job of the starter motor is to "crank" the engine, if it does this, weather the engine runs is going to depend on the fuel system and the ignition system and good compression. Try this: with one hand, hold the key it the "crank" position, with your other hand, move the gear shift (slowly)from park to reverse to neutral to drive. Make sure you foot is on the brake as it may start in gear. If it starts while doing this, you have a bad neutral safety switch.
Also, It wont stay running when you crank it by jumping the starter if the ignition switch is off. Try doing it again with the key on. If it starts with the key on, and you jumping it at the starter, you probably have a bad, or out of adjustment, ignition switch. If it does not start, with the key on and cranking by jumping the starter, then you probably have a fuel or ignition problem.
Try the above and get back to me. I can walk you through how to check for fuel and spark if it still wont run.

2004 Envoy XUV doesn't always crank.


I want to see if i catch your drift ! When you turn the key in the ignition switch to start , nothing happens ? Have you tried moving the gear slector to the neutral position to see if it starts then ? Park neutral safety switch problem , maybe .
Here is a description of how it works or how it's suppose to work .
Circuit Description (ECM/PCM Controlled)
Moving the ignition switch to the START position sends a 12-volt signal to the engine control module (ECM)/powertrain control module (PCM) Crank Request circuit. The ECM/PCM verifies that the transmission is in the PARK or NEUTRAL position. With the transmission in Park, voltage flows through the Park/Neutral position switch and feeds the starter relay coil.

On some vehicles the starter will continue to crank the engine with the key released until it starts or the crank command has timed out to prevent excessive heat build up in the starter circuitry or the ECM/PCM receives an engine run flag.

Why would turning the steering wheel while cranking engine gets my car to start?


The ignition switch in the column most likely has a break in it. So when you move the steering wheel, it moves the wire so it completes the connection when you turn the key. Have the ignition switch replaced.

Motor turns but does not start.


If moving the ignition around gets it to crank, you've got a bad ignition switch. A bad switch will occasionally function when moving the key around in the ignition or moving the switch around as you've described. The contacts wear with time (especially if there are a lot of keys on the key chain) and need replacing when constant contact can't be maintained to start the vehicle. Best of luck with your problem. Take care!

Engine will randomly shut off while driving at various speeds, sometimes while idling. also security system often does not work, and sometimes activates itself and sounds alarm.


1993 Mitsubishi 3000 GT stalls for no good reason, you never really know for sure exactly when it’s going to happen. It might start up right away, or after a few cranks. It may be hard to start in the first place. This could be caused by a faulty ignition switch, and could be easily repaired.
.5- If the engine cranks but wont start, hold the key firmly pressed inward or frontward while trying to start.
1- If the engine starts: energetically jiggle the ignition key back and forth while the engine is running.
2- If the engine stalls at any time while doing this, then you may have a defective ignition switch.
2.5- Remove the Ignition key from the ignition.
3- Remove the four screws from underneath the steering column cover.
4- Hold the lower half of the cover with both hands and pull it apart from the upper half. You might have to use some force to overcome the locking tabs, you might have to tilt the steering wheel up or down to remove the covers.
5- Insert the ignition key back into the key cylinder (ignition switch)
6- Turn the key to the on position (don’t start the engine)
7- Move the key in and outward while observing the opposite side of the key cylinder
8- If the opposite end of the key cylinder moves even a little, while moving the key; then the wiring side of the ignition switch has popped out of the key cylinder and needs to be secured back into place. (You don’t have to replace the key cylinder)
9- Press the wiring end of the key cylinder inward and tie it down firmly with a strong nylon zip tie.
10- This should take care of the problem.
10.5- Remove the ignition key.
11- Reinstall the removed parts.

Don’t use a rubber band to tie down the loose ignition part; it will break-off when the ignition switch gets hot.
