03 Mitsubishi eclipse, has fire and fuel pressure. Starts and runs fine on warm days. On cold days it cranks fast, hits a couple times but wont start. Im sure its still getti.g fuel bc i can smell it.

sounds like the timing belt it has a interference engine so if the timing belt broke you could have bent rods and cracked pistons or worse. good luck

SOURCE: 03 tiburon cranks,but wont idle or run

does your alarm system go off, and result in it not starting???

did you do a fuel pressure test? if you havent do it its cheep an at least you can elimanate that. if thats not an issue, then there is only two other things crank sensor, and if there is one cam sensor.

i think if you checked the sparking plugs and map sensors then check your distributer its maybe not delivering the current nedded to perform the spark to some of the cylinders

These International engines can be difficult to diagnose without the proper tools; namely Ford's I.D.S., or Navistar's DLC.

As for the o-ring the dealer was hinting at, they may have meant the o-ring on the fuel injection pressure regulator. I have witnessed these leak and cause difficult or no starting. This component is located at the rear of the engine below the turbo exhaust supply tubes. A specialty socket is needed to replace it (35mm 12 point socket which resembles an O2 sensor socket), although replacement is most likely unnecessary considering that your vehicle does eventually start. If this were indeed the culprit, your engine would not start. There is a test port next to this regulator to test oil pressure (bolt with allen head relief). A high pressure gauge which reads greater than 5,000 psi is necessary to test at this port. When your engine doesn't start, try checking what the oil pressure is at this port. A minimum of 3,000 psi is needed for the engine to start and 5,000 psi is prefered

Other sources of this problem could be the intake air temperature sensor, oil temperature sensor, or wiring compromises. It's a shame the dealer didn't want to spend the time necessary to pinpoint your problem. So glad I'm out of that crooked industry.
