Drop the PS hush panel and you will find the ECM just up behind the center.
Remove two screws, slide it out and down.
Unplug the two wire harnesses and voila.

My first question would be:"Why do you want to remove it?".

Default thank you

My car turns over but no spark. I replaced the ignition control module cap and rotor plugs fuel pump. People ive talked to said the computer might be the problem + the engine icon comes up all the time.

Quit throwing parts at it. Second follow the instructions here:

Retrieve the fault codes and report them here. The SES light (engine icon) is telling you where to start. At this point pulling the ECM will most likely do more damsge than resolve issues.

I'm away from my home computer and don't have the links to several posts on this subject on the Corvette Forum.

Here is a link to the codes in the '86 - '89 ECMs:
