Engine will not start. Floods.
Trying to diagnose a no start issue with my 85.2. The fuel pump works perfectly, fuel is being delivered to the rail, I have spark, I have tach bounce and the compression is good. I put a noid light on the # 4 injector connector and it didn't light up when cranking. I have been searching and have not found anything yet that will help. I am looking for any input.

I have good spark, so I believe there is power to the ignition coil.
I rechecked with a different noid light and I get to light up on each injector connector, but the noid light is dim with each pulse.

Here's short video of the engine cranking, verifying injector pulse:

Ok, i am getting fuel to the engine but the plugs are fouling every time I crank it. I am getting good spark, verified on each cylinder. I wonder if its not getting the correct amount of intake air.

Has this car ever run under your stewardship? If so, what were the last maintenance items you addressed?
Fuel to the rail does not ensure a running motor. Have you pulled the rail [with injectors connected] and verified fuel spray, while cranking, at each injector?
You have spark...where? At the coil, at the distributor, or at each plug terminal?
What does this mean? When you pull the plugs after cranking the motor, they come out black covered in oil/carbon/soot?

I have verified a bad reference sensor...
The car has never run under my ownership. I bought it non running. I pulled the rail and cleaned the injectors and replaced the o-rings and pintle caps. I pulsed each injector with 12V and verified that each one worked.
I have spark at each plug when cranking the engine.
When I crank the engine and then pull the plugs they are wet with gas.
