CAS is plugged in, correct?Fuel lines are connected correctly? (fuel filter side goes into the rail, fuel return line comes out of the FPR) All other sensors plugged in

If you have spark to all the cylinders then no, the ingnitor is working

How do you know you're getting fuel?

the fuel is flowing to the injectors and are clicking along with the smell of unburnt fuel in the exhaust

It's a bit of a long shot, but it's pretty easy to forget to ground the coil pack plugs.

Unplug the coil pack plugs and attempt to remove the harness, if you get caught on the ground wire by the head of the engine that rests near the firewall, your ground is most likely secured. You'll find it if it's not.

Also from what I've read about this car, I assume the CAS is misaligned by a tooth. Put the motor to TDC (make sure it's not 180* off) and check the timing if the above isn't the problem.But yea, i assumed the cas was the problem when i saw this go for sale. Mine was off when I bought my SR because someone replaced the broken CAS incorrectly.
