We live in south GA, the battery is new and has been tested, the starter cranks fine, we thought we solved the problem a couple years ago when we replaced the computer. When the temp climbs above 30 degrees no more problems.
There is a much richer fuel mixture during a cold start, the colder the engine the richer the fuel mixture
retarded ignition timing causing the fuel to burn for a longer period of time makes the engine heat up faster
anything that doesn't allow the mixture to be properly metered, like vacuum leaks, bad temperature sensors, or O2 sensors, MAF or MAP sensors, bad EGR valves or PCV valves hoses or tubes,
and or
anything that will cause the fuel mixture not to burn properly, like worn spark plugs, or any other ignition part, wires, cap, rotor, timing, compression, will cause poor start or no start conditions that are worse in lower temperatures,
also low voltage, week battery, slow cranking of the engine can also cause hard to start conditions
Run fault codes to check for ambient temp sensor problems . check for fuel pressure in the manifold

did you check the fluid level by removing the rad. cap? Radiator should be full to top. If Chryslers are low on coolant, the heater will not blow warm air.
SOURCE: 2001 pt cruiser limited won't crank
needs a battery but be careful cause sometimes a bad alternater will cause the battery to go bad
SOURCE: replacing a starter in a PT. Cruiser 2001
Remove battery and battery support you'll be able to undo starter bolt's trough there and slip starter out.
Testimonial: "This didn't help, because you had to remove the engine structural collar under the starter to get at the starter bolt. It was more complicated."
