Code P0350 Ignition Coil Primary/Secondary circuit 2004 Kia Sedona

I have a 2004 kia sedona 6cyl and about a week ago my car wouldnt start. After checking all of the fuses, the camshaff position sensor, main fuse and more. It was determined that the computer was not working. Went to a used parts place and picked up a computer for $100 put that in and it fixed about 65% of the problem. But still it wouldn't start. So I changed the ignition failure sensor and it starts but now it shakes a lot and the Diagnostic code it gives me is P0350 which is Ignition coil Primary/Secondary circuit. There is no spark at the middle coil. But when I move the middle coil to another spot there is spark. So I don't think the coil is messed up. Could it still be the computer?

It could be the computer, but it could also be the wire. You can check the resistance of that wire, or simply use a known good wire to see if that is what it is.

P0350 - Ignition Coil Primary/Secondary Circuit Description: Each ignition primary circuit is continuously monitored. The test fails when the powertrain control module (PCM) does not receive a valid ignition diagnostic monitor (IDM) pulse signal from the ignition module (integrated in the PCM). Possible Causes:
  • Open or short in the ignition START/RUN circuit
  • Open coil driver circuit
  • Coil driver circuit short to ground
  • Damaged coil
  • Coil driver circuit short to VPWR
Diagnostic Aids: Use the 12-volt non-powered test lamp to verify START/RUN voltage at the ignition coil harness connector.
Check the coil driver circuit for open, short to VPWR, or short to ground. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test JE .

- Lack/Loss of Power
- Engine may be harder to start
- Engine hesitation
- Rough engine idle
P0350 Hyundai Description
The ignition signal from the Engine Control Module (ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

Does the vehicle have coil on plug ignition or coilpack ? And it's not primary or secondary coil malfunctioning It's primary or secondary circuit . I'm assuming it has a coil pack because you say plug wires.
P0350 - Ignition Coil (Undetermined) Primary/Secondary Circuit Malfunction Each ignition primary circuit is continuously monitored. The test fails when the PCM does not receive a valid IDM pulse signal from the ignition module (integrated in the PCM).
  • Open or short in the Ignition START/RUN circuit.
  • Open coil driver circuit.
  • Coil driver circuit shorted to ground.
  • Damaged coil.
  • Damaged PCM.
  • Coil driver circuit shorted to VPWR.
P0351 - Ignition Coil A Primary/Secondary Circuit Malfunction See the description for DTC P0350. See the possible causes for DTC P0350.
Pull the spark plugs out an look at them , check the gap ,if too wide replace them . If the spark plug gap gets too worn ,the spark won't jump the gap. It will find the least resistance path to ground ,and it will do it inside the coil . Going from the secondary circuit back to the primary coil an to ground through the PCM - engine computer . The PCM has transistors inside that open an close the primary side to ground ,this builds up a magnetic field around the secondary inducing high voltage spark . Well this can short out the transistor inside the PCM . Most of the time that's what these type codes mean . The PCM would need to be replaced an programmed . This can also damage the catalytic converter. Your best bet , take your vehicle to a qualified repair shop.

po350 is coils 1,2,3,4 failed. The ECU has decided that there is a problem with those relays. They may be bad but check related items first. Could be damaged wiring or could need new spark-plugs. good luck.

Check Ignition Coil 1. IG KEY : OFF , Engine : OFF 2. Disconnect ignition coil connector B-20/ B-21/ B-22. 3. Measure the primary coil resistance. - Connect the negative (-) terminal of a 3V power supply to terminal 2 of the power transistor; then check whether there is continuity between terminal 3 and terminal 2 when terminal 1 and the positive (+) terminal are connected and disconnected. A.
