I need to know how to change the ECM in my 1997 Chevy Caviler with a illustrated view

If everything plugged into the engine without changing anything I would try it with the cavaliers ECM there is a lot of vehicle specific information in it. These ECMs are not programable. I hope this helps you, take care

Check your owners manual for the correct shift pastern...It is a natural H pattern, with 5th gear upper right...reverse should be all the way to the right and lower right to engage...the knob does not always indicate the correct pattern...may have been changed...also be sure it is a 5 speed...most of these Cavaliers were 4 speeds...with reverse being upper right instead of 5th gear upper right...confirm in your owners manual if possible...will show illustration...Hope this helps.

It's on TDC so align marks on cam shaft and crank shaft with center of cam & crank shafts and the ECM will go from there. so you will have to change the timing chain if its loose or worn out.

First step should be to call for customer support, and to check on recalls, sometimes your dealership service department can answer technical questions too. www.chevrolet.com or 1-800-222-1020

You need to remove the fuel line and blow back into it to remove any debri that has collected around the fuel pick up. Be sure the fuel filter under the car is changed as well and the fuel filter on the firewall. Also fill the tank and put 2 quarts of rubbing alcohol in the fuel tank to dry up any water.

turn key to the on position the theft light will flash (can take up to 15 min) when it stops flashing turn key off and this will re program your computer to your ignition car should start right up

Check the fuel/air sensor and air filter. When you first start the car only press the accelerator pedal once. If while turning the ignition switch you here a grinding noise that would be your starter going out. The smell of fuel signals that your car is either flooded from pressing pedal or fuel mixture is incorrect. Hope this helps.

could very well be a head gasket.
