Default MS1 No Spark 1 and 4

Hey,

All of the sudden my car runs really bad, i am not getting spark for cylinders 1 and 4. It barely starts and runs around 3-400rpm, for about 20 seconds of running only the 2 and 3 exhaust manifold pipes get warm and 1 and 4 stay cold. Pull the plugs 1 and 4 are wet with raw fuel, 2 and 3 are dry and covered in carbon. I have tried a different cam angle sensor, plugs, and stock coil packs and plug wires as i have toyota cops on there normally. Car drove fine to work sunday night, come out in the morning and it barely starts and runs like pewp.

Its a MS1 PNP, is there anything on the ecu i can check that sends the spark signal? Any other ideas?

Thanks in advance!

Something between the 1/4 coilpack and the ecu is broken. A wire.

To eliminate broken wire scenario, or. Bad ms1, you can try to put oem ecu back in?

I think it may be MS related; for mine on the main board D14 LED is spark output A and D16 LED is spark output B. With power to the ecu only D14 LED is on and it has like 1.7 volts, i know before i have seen both of these light up with power to the ecu. Any ideas?
