Easy way to keep car from starting?

[G FORCE]

I need to temporarily disable my 318is. In previous cars I would just pull the ECU fuse but I can't seem to find such a thing from the fusebox diagrams online. Any quick way to keep the car from starting? I pulled the fuel pump fuse but it still allows the car to start. Noob question but thanks for any help!

Pull the motor out

Add some padlocks to the doors, too! That'll show 'em!

lmao! Sometimes I feel like lighting it on fire! However, for now I just unplugged the plug wires. Tomorrow I'll just pull the starter fuse. Didn't even see that!

Install an automatics neutral safety switch, then break it.

Take the negative battery cable out.

I thought about the negative battery cable but unfortunately the vehicle only locks when locking the trunk. Once I disconnect the cable, I can't lock the doors >.<

Disconnect the distributor from the coil. No spark.

Why are you trying to disable it? But yea unplug the battery or just take the main relay out.

Install a 13 button OBC and use the code feature.

Keep the key away from the ignition.
