Had to smash my rotor..

When replacing my rotor I had to use a screwdriver and hammer and smash it out..
It was original and so jammed on with rust, ect. this was the only way to get it off.
I'm getting ready to replace the module thinking I might of damaged something internally, though I was tender.
Ive replaced just about everything else and the Blazer still wont start. Is there any other kind of damage I might of done or should check if the new module doesnt work? I have good fuel pressure, spark, ect.

Would help to know year, and engine at minimum.
