What happens if you dont pull the ECU fuse when doing a compression test?

I read in another thread that you are supposed to pull that fuse?

I just did a comp test on my wifes 95 Civic.. I disconnected the injectors, removed all the plugs, and laid the plug wires to the side. Checked all the cylinders.. which checked out ok... but when I put everything back together the car wont start. Checked for spark.. no spark.

Did I just fry the ECU? I checked all my fuses and nothing was popped.

Thank you.

 

umm you dont pull the fuse for the ecu.. you just pull the fuse for the fuel pump. this keeps the cyclinders from filling up with gas. Theres no spark after just pulling the ecu fuse... thats not right, you did something else. Check your fuses.

 

Thats the thing.. I didnt remove any fuses when I did it. I did disconnect the injectors though.

I read somewhere that I may have fried the ignitor and coil.

 

Just did a search.. didnt realize I needed to search archives. Im gonna replace the ignitor and coil. We'll see what happens.
