only spark on two plugs

[bcowx06]

ive been looking around for reason i would only be getting spark on 2 plugs. heres what i have come up with i switched the coil, plugs, wires, power transistor and my 1g cas. but still nothing what else could cause me to not get spark?

Which 2?

2 and 3 but i switched the wires on the back of the coil then i get spark on 1 and 4

only thing you haven't touched is the ECU...
how were you testing for spark and what 2 cylinders aren't getting it?



^^^ my bad, i guess i took to long to post and the question already got answered

The ECU or wiring from the ECU to the power transistor.

i switched the wires on the back of the coil and got spark on the other 2 plugs. i had a extra power transistor pluged it in and same thing. does the transistor need to be bolted to the intake? because i was getting spark on all 4 but i put another intake on now this is going on.

that eliminates the spark plugs, plug wires, coil pack, & ignitor right there. i know you already replaced the cam angle sensor but id be skeptical since thats 99% of the time the culprit. keep us posted, theres only a few things that can cause this so we'll get it figured out.

im testing the CAS by rotating the nipple thing of the CAS by hand i hear the fuel pump kick in and the plugs spark.

look what i found!
