Default Sudden cold weather, Pt has to turn over several times to start.

Here in Las Vegas Its been in low 80s in the daytime and High 60s at night. all of a sudden weather this week at nights drop to mid 40s to low 50s, for the last two mornings my kid goes out to start the cruiser up and he has to try a few times be for it starts..

New battery, turns over great, once it starts it runs great, even after just a short trip to the store " park go in come back out 20 minuts later " it starts right up first try, we've let it sit for an hour or 2 and it starts right up so long as the engine is even slightly warm.

I've been scouring the forums trying to find any similarities but cannot seem to find any post related to this problem..

Only thing that changed from last week to this is an oil change from 5-30 reg oil to 10-30 full synthetic oil and the sudden cold temperatures at night.

So how do we logically start eliminating whats not the cause.. there are no key dance error codes, no engine lights, 2001 pt cruiser limited edition 113k miles, two weeks ago we changed out the Battery, Alternator, Radiator & temperature sensor and it been Cruising along nicely until yesterday when it go cold.

Thanks for looking.

Miles on your PT? @ 112,000 have you changed your timing belt and water pump?
Not that it will cause slow starting, just a reminder.

When its cold, try cycling the key several times without starting it, then see if it starts faster, fuel pump may be getting weak.

Plugs and wires age, ever changed them?

Have no proof, but was told by the shop mechanic where I bought the car that the timing belt & water pump appeared to have been changed, the lady that traded the car in for a newer model pt had stated as such too.

Sparkys and Wires no..

Right now I'm working on getting new suspension parts, control arms & upper/lower motor mounts.

Do you know what miles the timing belt was installed at? May want to replace it just so you know how old it is ^^;. You cant control what you cant measure.

Usually with mine, turn the key to accessory, wait a second for the fuel pump to stop, then go to ignition. Fires much easier every time.

That is exactly what I told my kid to do. Ill know to night if that helped.

I agree with you on the Timing belt and water pump, Not knowing for sure bothers me.

The timing belt would be a great opportunity to check the torque struts as well. As well as the crank seal and engine mounts. It just keeps adding up

Man you hit the Nail on the Head, I've never seen a car where every part.. is the week link..!

Good thing PT parts are a dime a dozen, and the labor is free.

As others have posted check to make sure the fuel pressure is 57+/-5 PSI.

Went to my local Oreillys and the nice folks there let me borrowed their pressure tester, and code reader.

They plugged in their code reader and found nothing, all clean.

It was nice & easy being able to just plug in to the fuel manifold for the pressure test..

The pressure tested to 56 PSI, then dropped to 48 PSI over a 10 minute period.

So is there a PT Doctor in the house that can say if thats bad or ok.? Do I need to replace the Fuel Pump assembly..?

In your second post, you answer sparkys and wires, no. I'm guessing that means that the plugs and wires were NOT changed. Believe it or not, weak plug wires can cause a slow or even no start in colder weather. It's a resistance thing. If you didn't have the plugs and wires replaced, do yourself a favor and go get some OEM Champion copper plugs and gap them at .042 and replace the wires too. I'm pretty sure your PT will start much better. If not, WTF? You've got a new tune up finished almost. PCV valve and air filter would top it off.
