'91 100q 5 injectors replaced - now car wont start

[Steve]

I agree with the washed down cylinder wall theory. RX7s are famous for this. I had this happen on an FC that I had that required removing the fuse for the fuel pump and then squirting ATF in the cylinders and spinning the engine with the starter to get compression back. 

The motor sounded like a timing belt had broke and it spun fast with no compression before I did the fuse/ATF thing.

I wonder if your injectors are spraying more gas than they should causing the cylinder wash...

I stand by the mention of possible washed down cylinders. Squirt some oil in each cylinder and see if compression improves.
