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

Tried oil in the spark plug hole to no avail. Timing marks are lined up.

My mechanic advised that he thinks he is seeing coolant in 3 spark plug
holes.

I am baffled. Everything else in this car is in great shape.  

I am about to part this thing out or just sell it as is. It's in Northern NJ.

Any other advice?

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.
