Over the past few days I've had the cap and rotor, throttle position sensor, and the idle air control valve changed on my car but it is still not starting. We looked up codes and now it shows codes 12, 41, and 55, I've found 12 and 41 but even Chrysler says my year model doesn't have a code 55 (flexible fuel sensor) what could possible be wrong with my car?
Which engine do you have? Code 55 means "end of message". 12 just means the battery was disconnected recently. 41 is related to the charging system. It is not related to the no-start. Have you checked fuel pressure? Does it have spark?
