Hi,

Are you getting a signal from the PCM? I attached a picture below showing the wiring between the two. The coil that fires cylinders 2 and 3 is triggered by the PCM via the dark blue wire with a tan tracer. Check to see if you are getting a signal from the PCM. If there is no signal, check for corrosion or damage to the connector at the PCM. The PCM is on the firewall behind the power distribution box.

Let me know if this helps or if you have other questions.

I checked the connectors and wires from PCM to coil checked out good. Do you think the PCM is bad?I have new coil on it it isn't firing from 2 or 3.

I would check at the PCM for a signal to coil 2 (for cylinders 2 and 3). If there is no signal, then it does sound like the PCM.

Let me know.

I have no signal off the blue wire for 2 and 3. I have signal from the 1 and 4. I went to pull a part and got a new (used) PCM the only one they have with a turbo was a 2006. Will it work on my 2005? And will I have to have it flashed? And if so how and who can do it?
