Hi Karen,here's a link to a repair guide on your ignition coils. GET 35 GIFT CARD FOR EVERY 100 SPENT ON ONLINE SHIP TO HOME ORDERS Here's the codes meaning. P0351 Ignition Coil Primary Secondary Circuit Malfunction

Follow one of the plug wires from spark plug back to thr IGNITION COIL!.. There it is!!

MAke sure its in park( just move it though the gear shifts) sometimes the neutral switch gets sloppy age/usage/transmission swap etc. Check for voltage at the coil positive terminal when the ignition key is on. YES there is voltage, the problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit). If there is NO voltage at the coil, the problem is on the supply side (the ignition switch or ignition wiring circuit). Check Relays and Fuses.

This is for the 3.0L engine:

3.0L Engine

1. Remove the engine appearance cover.
   
2. To access the right bank ignition coils, remove the upper intake manifold..
   
3. Disconnect the electrical connector from the ignition coils.
   
4. Remove the bolts.
   
5. Remove the ignition coils.
   

To install:

1. Replace the ignition coils.
   
2. Connect the electrical connector to the ignition coils.
   
3. Remove the upper intake manifold for the right bank ignition coils.
   
4. Replace the engine appearance cover.
   

I searched under 'ignition module' on autozone.com and 'no parts for ignition module' turned up.
I looked under DIS or Distributorless Ignition System and found the coils are inserted in the top of the engine and this tells me that it's likely that the ECM or PCM controls the spark on these cars.

Hi there,

First of all, make sure the ignition switch if off. Then you remove the ignition coil electrical connectors from each coil pack. Then you number or label each spark wire so you can put them back in their original location. Then remove all spark plug wires from ignition coil pack. Then remove the ignition coil pack, four mountain screws and remove coil pack

Hope these help.

Please find the ignition coil location in the picture below

You dont's say what engine but the coil is easy to spot, the coil lead at the distributor is the one in the center of the dist cap. Follow that to the coil. here is a picture of the coil.

There is no cap and rotor, as the vehicles igntion system is DIS (digital ignition system). The recommended tune-up on these motors require sparkplug and coil replacement. The coil type in this vehicle is COPs (coil over plugs). Usually moist and oxidation develope on the sparkplug chamber walls from faulty or worn coil boots. This causes the coil to short, they must be replaced at 75,000 miles at the same time the sparkplugs are replaced. Typical symtoms are: Vehicle stalls (restarts and runs normal), intermitted jerks/sputter while driving, misfires, rough idle, severe power loss. Hopefully this helps
