linda1947 is keeping the peace
I have a 2004 PT Cruiser non turbo (45K). I was referred to this site by a person who says MX-5 may be able to help. The code showed that my coil or spark plugs were the culprits. I changed the plugs, tried to start the car, it turned over, but didn't start. After the third try the engine will not even turn over. The battery is fine. I turn the key and nothing. I tried both keys that I have.

What originally happened was, I was on my way to work and a block from my home and the check engine light came on and started blinking. The engine putt putted all the way home. I turned it off then tried to restart it. It started but ran very rough, coughing, sputtering and popping. I pulled the code P2302 only. So, I changed the plugs (my husband and a couple of friends, actually), they were really bad,now it will not turn over. The lights are bright and the alert tone loud and clear while the key is in ignition with door open. We have checked and rechecked all the wires.

Can anyone give me and idea of what to do next? I really cannot afford to take it to a mechanic right now. Thanks for any advise. Sincerely, Linda

Please don't think I would think any idea was stupid. The plugs are secure and in the correct order. The car turned over when we first tried to start it...then walla..nothing.
Thanks for replying. Linda

P2302 is not a good code.
You may have read P0302 for cylinder #2 misfires. The cause of a #2 misfire is spark plugs and wires. A coil would fail for 2 cylinders, as each coil winding fires 2 spark plugs at the same time.

Now that it won't spin the starter, and you have bright headlights that do not dim when the key is turned, means you need an experienced tech before you really damage a $3000 engine.

I'm not a doctor, so I don't perform surgeries.
I'm not a carpenter, so I don't try to build houses.
I'm a mechanic. I fix cars.

What scares me is the number of untrained, and well meaning, folks who try to work on someone's $25,000 investment. The potential damage risk is certainly worth letting a professional tech work on your primary transportation to your income generating career.

Thanks for answering. It was P2302. I was hoping it was something simple, but then it never seems to be with my luck. I really cannot afford to take it to a mechanic at this time, so I guess it will have to sit for a while.

Do you think maybe the starter went out? Should I try changing the coil? You said "it" won't spin the starter. What is "it"? Thanks for your time. Linda

The "it" I am referring to is the starting system.

The rare code P2302 refers to the ionization time for the spark plugs, wires, and coil.
Once you repair the starter circuit fault, you need to check for spark at the coil. If it has spark, the wires and plugs are at fault. If not, the coil driver circuit should be checked. Coils fail very rarely on Chrysler ignition systems.

Linda, MX5 is usually "spot on". I replaced my coil with a Sceamin Demon coil at 5k miles and I will sell you the factory one for $20 + actual frt. if you want to try that. It's your call. email me directly if interested. <dicept1@aol.com>
good luck, Joel
