If you don't pull the relay then you are using the fuel pump. If it is flooded by chance then using the pump is no good.

Did you do a compression test after the car died?

Use the air intake that runs to the air box for the spray.

And sporadically check the voltage on the B/Y wire at the lead coil w/key to on to see if it is proper or too low. If too low then the cause needs to be addressed.

If you haven't checked the compression after it died then it should be a priority to do so regardless of previous results.

When the car started up was the relay pulled? If you believe the engine is flooded then the relay being plugged in just adds more fuel. If you believe you the engine has been properly deflooded then the relay needs to be plugged back in and before starting the car you might try jumpering the fuel check connector.

There's a Green check connector near the lead coil. It has a single wire to it that is Orange. You ground this wire to the negative battery terminal followed by turning the key to on and the error codes ,if any, will be displayed.

Overall or 3 even bounces? Your overall compression can be higher and still have a tired engine.

Put oil in the plug holes too than try and start it

Before you place you CAS triple check your timing

O2 sensor won't stop the car from starting

I bet its a big *** leak somewhere.

I see you still have a stock turbo inlet duct. Check it carefully.

If you've had the intercooler off, check those hoses too.

Do you have a spare CAS? You can plug in a different CAS and w/key to on you spin the CAS wheel and you'll hear the injectors and plugs click.
