So my Sebring died on the highway today. It's the 2.4. the dash lights stayed on but the engine turned off. Now it'll start and stay running as long as I hold the key in the start position, but dies right after I let it return to the run position. I just changed the ignition switch (not the lock). I've tried both keys and they behave the same, and I've checked the fuses. I'm not getting codes from my reader. Any ideas? Help!
