My 2004 Intrepid will occassionally turn over but not start. This began 5 months ago and has gotten more and more frequent. Everything seems to be working fine, accessories, fuel pump etc. Just won't start. It can be wet or dry, hot or cold outside. Sometimes it will start in an hour and sometimes it's up to 5-6 hours before it starts again. I checked for codes and the only thing that showed up was "done". I'm really getting incredibly frustrated. I'd love it if someone has any insight.

Do below this will tell you something if its a fuel or spark problem.

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

Fuel pump and Injector/s checks out-start checking the ignition system-power to coil, coil/s itself, distributor pick-up, control module, Cam and Crankshaft sensors.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time
