Yes, leaving a key in the ignition can potentially cause a fire, especially if there are underlying electrical issues or if the ignition system malfunctions. In some cases, a short circuit could occur, leading to overheating and igniting nearby materials. Additionally, if the vehicle is parked in a hot environment, the ignition components might overheat, increasing the risk of a fire. It's always best to remove the key when leaving the vehicle unattended to minimize risks.
Yes, IF the ignition SWITCH was left ON. I suggest charging the battery, and then have it tested at Autozone both of which are free.
The ignition key.
Check door pin switches
It can cause the ignition lock cylinder to not turn. If it turns then the key is not why it will not start. Look into the ignition switch, starter, battery, or connections.
To remove the ignition switch in a 1981 Corvette, insert the key into the ignition while leaving it in the "off" position. Insert a straightened paper clip next to the key, turn the key to the "Acc" position, pull the key and clip out together, and place the coil down.
The back of the ignition key cylinder is probably broken.
A fuel leak and a source of ignition such as faulty spark plug wires.
The cause of the key sticking in the ignition, after the car is turn off. This is caused by the button on the gear shift knob, not coming out all the way or sticking.
If you have no spark, check the ignition coil and ballast resistor. If the engine tries to fire when you turn the key to off position, there may be a short in the ignition switch.
Tampering or replacing ignition that does not match up with your key will cause your security to shut your car down.
There are several possible solutions to reset the immobilizer, assuming you can get into the car, the reset can be done by putting the key into the ignition and leaving the key there without starting the car.
The most likely cause would be the stator assembly. By disconnecting the cannon plug for the key switch harness, at the engine, you can isolate the problem to the engine, or the ignition switch / harness assemblies. With the harness disconnected, spin the engine over with a starter button, connected to the solenoid. If the engine now has fire, the problem is in the ignition kill circuit, (ignition switch, emergency kill switch, or harness assembly). If a no fire condition still exists, the problem is in the ignition system, on the engine itself. The stator, and related ignition components can be tested with a volt / ohm meter.
