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

[Fred Munro]

Chris;

If the engine is turning and is spinning as freely as you say, it sounds
like you have no compression on any cylinders. If some cylinders had
compression, you would hear the pulse as the engine turned over. Did you
install the injectors and seals properly? Are the spark plugs installed? You
might try a compression test on every cylinder to verify compression or lack
thereof. 

Good luck!

Looked the car over again. The timing belt is intact and the engine
definitely turns. The engine just turns smoothly and evenly without the
usual rhythmic sounds. The sounds is one of constant, mono tone crank.

I am not sure if this is relevant, but I moved the car about 40 feet by
engaging the started and the car in neutral.

I will check the fuel delivery some time as well. 

Thanks for your continuing help.
