Engine will not turn over?


Asked by Sep 07, 2013 at 10:40 PM about the Chrysler PT Cruiser

Question type: Maintenance & Repair

My 2008 pt would start up and then die about 2 seconds after starting. I pulled the spark
plugs and found that they need to be replaced, however, when I tried to turn the motor
over to check the spark, nothing happens. The motor will not turn over when you turn the
key. What would cause the motor to stop turning over when a spark plug is pulled? Even
after reconnecting the plug and wire the motor will not turn! Any input here?

the security has been activated. Does your vehc. use the gray headed key? do you have a key fob? try unlocking doors with it. Security will allow it to try to start 2 times, then it locks it down. Its poss the antenna for the security key has gone bad. the antenna activates the security key. Try disconnecting batt. and retry to start. If it does start. keep the tools nessary to pull bat. term in car. You will have to take vehc. to dealer to have the skim module replaced, if this is the problem.

It does have a key fob on the key, however, my wife took that key with her so I was using the spare key which does not have a key fob. She had driven the car home and parked it. She mentioned it had been sputtering at times throughout the day. I figured it needs new spark plugs but wanted to drive it first to see for myself what she was experiencing. When I started it up it would run for a few seconds and then shut off. I tried this several times. Sometimes it would start up (and then die) and other times it would just crank and crank. I then pulled the plugs to inspect, but when I tried turning the motor over to check the spark it does nothing....

No check engine light. Pretty sure it was the key. It's black. I used her key ( the one I was using was a copy made at home depot). I also changed the plugs and wires. Runs fine now. I had no idea the key would make any difference

the gray head key has a transponder in it. It deactivates the security.


When you say fob, are you talking abt. the remote or the keyhead?As some remotes are also gray.
