Please HELP freshly built motor, car cranks no spark, no cel

[95eclipser]

Hey everyone i need some help figuring out why my car will not start or even spark for that matter. I have fuel and the car will crank for days, but i am not getting spark. The cel light does not come on either when i turn the key. But i am unsure if that is because of the AEM EMS unit that i am using. Please help it has been two years since i have driven this car.

Little background on the car

Sure is. CEL functionality is gone with the EMS unless you program it in for specific fault conditions.

You need to datalog.

I don't think i can, at this point i am unsure if i can even connect to my EMS.

Might be easier to find a local who would let you swap ECUs and then pull the codes it throws.

Why can't you connect to the EMS? You might be able to find the problem pretty quick if you could log an attempt to start it.

My money is on the CAS or it's wiring, but I'm not knowledgeable on how the EMS handles fuel/spark triggers.

That's pretty critical to figure out. If you can't, I wouldn't be surprised if the EMS isn't the root of the core problem.
