Ive got compression, and the injectors are spraying gas. The only code im getting is this "circuit B malfunction", and that is number 3&4 witch are on the same bank of the coil pack. Yes ive tried 2 different coils and got the same results. My question is, would it be the PCM not sending the signal to the circuit "B" to fire?

That codes indicates a problem with the circuit on ignition coil for cylinder #2. It could be the coil, the computer or any of the wiring in between.

Not trying to be a smart a**, but 3&4 are the ones not fireing, Number 2 is working fine. Ive got four wires going into the plug on the coilpack, one is 12 volt, and the others are low voltage, is that the way it should be? Im agreeing with you, i think its in the pcm, i just need a second opinion, its a customers car and weve allready sunk alot of money in it thus far.

3 and 4 share the same coil. You check for a coil trigger at pin 3 brn/green wire at the coil pack connector while cranking the engine?

I wouldn't just in case for some odd reason your test light uses to many amps and burns out the driver in the PCM. You have a logic probe or test lamp that uses LEDs? You might be able to wire in an injector noid light too.
If you have no trigger at the coil connector, you'll have to make sure that you have no trigger at the PCM connector to rule out a wiring problem before going after the PCM. I don't know if you know this, but one side of whatever you use has to have battery voltage because the PCM driver grounds the coil circuit to energize the coil. When it wants to fire the coil it opens the circuit. The lamp should flash. If it stays on or doesn't come on at all, then you need to verify wiring before going after the PCM.

discrete, i figured out how to test it. i have green with a blue that is 12 volt, i tied my noid light in an jump it to brown with blue and get a pulse, and the same with the brown with yellow, im getting no pulse with brown with green. the trigger wire for 3&4 coil bank. would you have access to wire diagram to show me where the brown with green goes so i may by-pass it for now instead of pulling wireing harness apart just to rule out broke wire? the wires come out of the coil and go under the intake, and from there im not sure.
