no spark? desperate

ok i tested the coils they test good tested the resistance in the wires they test good pull my plugs and there is fuel on them but i run my pump off of a switch so my questions is other than timing or igniter what could my problem be? i dont think im getting enough spark becausde sometimes it wants to pop but just wont start the only thing i changed was put a t3/t4 70 trim turbo and an aftermarket manifold what could the problem be?

depends on what you are running for an EMS, if you are running the AFM still then i would check your intake for leaks and do the deflooding procedures.

Is the CAS plugged in?

Power up the car after removing the CAS from the engine (leave the harness connected).

Unplug a plug wire and place it near a ground. Spin the CAS. Spark?

If not, then check for 12V at the coils. If you have 12V, try a different CAS.
