Default PT Cruiser won't crank / start

My girlfriend has a 2005 PT Cruiser convertible, will not crank... no apparent previous symptoms

I've checked all fuses, swapped out start relay.

I jumped posts 30 and 87, and the starter cranks reliably, so I know both the battery and starter solenoid are good. Post 85 has very low impedence (.145 ohms) but is not ground.

Posts 85 and 86 fluctuate very slightly (not measurable) but stay at 0 voltage when I turn to start. I understand they are supposed to get 12v from starter switch. Though I don't regularly drive this car, it seems that the starter switch does not have a positive spring return from the start position; I suspect this might be a physical problem

I also understand there is an actuator pin that can go bad behind ignition lock. 1) Is there a way to further test the ignition switch before I take it apart and 2) Is there something else for me to test / troubleshoot?

There is no check engine light, car will not start in neutral, door lock remote works, and moving the steering column does nothing (tips from other posts

Someone just had a similar deal. Turned out to be the ground behind the airbox.

Thx. It's dark now (and still raining). I'll check in morning. Am I looking for a groundstrap or cable to the firewall? Can you be a little more specific as t owhat I'm looking for?

The ground cable runs to the driver side inner finder hidden by the air cleaner box. Any connection or junction is a possible dirty connection.

Thanks. Actually, I think I saw that; a acble clamped w/ 2 10mm bolts. I checked f/ tightness, but did not take off to clean. Will go thru all tomorrow.


I also read that pcm could be bad.. not sending neutral to relay to engage starter. Don't know how to check that, other than replace pcm...Really don't want to go there

I would go through every cable connection from battery to starter before I would spend any money. Do the cheap stuff first.

We would need much more information on your exact symptoms, model, year, turbo/non turbo, any engine codes etc before knowing what to tell you lol

My PT stopped on me three times today. Each time I was driving, foot on gas pedal and I felt the pedal lose pressure as the car came to a stop. The car still had battery power but would not crank. After a few minutes it started up and I drove it. The third time it stopped on me (about 30 minutes later) it wouldn't start. Still won't crank up. There is battery power, the starter isnt broken (my husband tested it). We don't know whats wrong. 2004 Pt Cruiser GT

If you any where near (or past) 100,000 miles,it could be the timing belt......Easy way to check,is to have your husband remove the camshaft position sensor,and while he's looking inside the opening,you try to crank the car....If it doesn't turn,it's the timing belt.
