I've got a 2003 3.0 with a manual trans.

I'm getting no fire to the coil pack on cylinders 2 and 6, 1,3,4 and 5 are getting fire, it keeps throwing the code p0353 for coil pack c primary/secondary malfunction.

It has a new coil pack, new plug wires and new plugs.

I checked the wires coming from the PCM to the plug that plugs into the coil pack, they're good.

anybody have any ideas?

 

l Disconnect suspect coil (determined from the table).

l Key on, engine off.

l Measure voltage between IGN START/RUN circuit at coil pack harness connector and ground.

l Is voltage greater than 10.0 volts?

Yes
KEY OFF. GO to «JE5».

No
IGN START/RUN circuit fault. KEY OFF. CHECK condition of related fuses/fuse links. If OK, REPAIR open circuit. If fuse/fuse link is damaged CHECK IGN START/RUN circuit for short to ground. REPAIR as necessary. COMPLETE Misfire Monitor Repair Verification Drive Cycle (REFER to Section 2, «Drive Cycles»).


The wire they are talking about is rd/lg. Bext step is.


l Connect incandescent test lamp between IGN START/RUN and suspect CD circuit (determined from the table) at the coil pack harness connector.

l Disable fuel pump by disconnecting inertia fuel shutoff switch.

l Observe incandescent test lamp while cranking engine.

l Did test lamp blink consistently?




Yes
KEY OFF. GO to «JE12».

No
KEY OFF. GO to «JE6».
