Not sure on your'e question here. The ECU controls most of the electrical components of the modern day care, air flow, fuel mixture, idle speed, etc... If you remove the ecu, sure the car won't start.
If your ECU becomes damaged by an electrical fault or something else, most times it will switch into "crawl home" mode where the car has very limited speed. Our old Magna blew it's ECU after jump starting too many cars the wrong way and we had no working gauges on the dashboard, the engine ran poorly and we "crawled" home at 35 km/hr.
Now if the ECU is connected to an immobilizer, then it also will not allow the car to start unless the immobilizer is disarmed. Some models can be deactivated by key if the remote stops working, and some can be simply disconnected. However, leave it to the pro's as ECU's are expensive to replace.

What car alarm can also shut down the car?
The GSM car alarm will also shut your car down if you tell it too and if you know when it needs to be shut down. The Viper Car Alarm company has a wide variety of car alarms that also shut down the car. These are also called car immobilisers. They come in a range of prices that will meet your needs. There are other companies who also make car immobilisers, however the Viper brand of immobilisers seems to consistently receive the best feedback. anonymous@oola.com
