Tip & How-To about Cars & Trucks

Want to bypass your vehicle security system?
The short answer is you can't!

All modern cars have alarms and immobilizers. There is a chip in the key and a chip in the ignition lock. If both are present, the ECM (engine control module) releases power to the ignition circuit. When you turn the key, the starter spins the engine and you get a spark. If any one of those three items are not in the chain, you get the engine to turn, but no spark. There is no way to beat the system. You have to fix what is wrong, not find a way around it.

The immobilizer is in place to stop exactly what you are trying to do.

Unless you are a keen home mechanic you better off taking this to a Good Mechanic as it's a time consuming, fiddly job.
**Note* Make sure your front wheels have blocks in place to stop it rolling and Sometimes brute force is the only way to get the drum off.*
With the vehicle safely raised off the ground, does the wheel spin freely with the park brake off? Yes? The drum should just pull off. You might have to tap the drum between the wheel studs/hole with a hammer to loosen any rust holding it on or use a 'drum puller' tool.
Not spinning? There is a star adjuster inside the drum you can 'back off' to move the brake shoes out of the way. That is a slow fiddly job where you have to turn the adjuster one notch at a time with a flat blade screwdriver. This is done through an access hole on the back of the drum or one of the bolt holes on the front of the drum. If your going to do it yourself try searching the YouTube link below.

If there is no obvious external coolant leak, the coolant is being burned in the engine and going out the exhaust pipe.
You could have a leaking head gasket.

Disconnect the battery hot lead for a little while so the computer has to reset. A half our is time enough. Then reconnect your battery, turn the switch on, you'll see the check engine light which is normal, start the engine and the light goes out. If it doesn't go out upon startup, the #2 sensor wasn't all that was faulty. Put the diagnostic unit back on it to find another code and research that code to find the problem.

Could be the security system is preventing the engine from cranking/starting.

I suggest you read the vehicle handbook to discover more about this.

When you get bizarre electrical like that, the very first thing you check is for corrosion on the ground connections in that circuit. A corroded ground can't carry the added load when you turn on the signals.
