Default Car won't turn over sometimes...

OK Guys,

I'm sure someone has come across this before, but here's what happens once in a while when I try to restart the car once it's hot, and I've already driven it for a while.

I turn the key, and the fuel pump as well as all the dash lights come on, but the starter does not turn, no sound, the car won't start.

The starter is fresh, don't believe that's the issue, and the battery is good.

If I turn the key on and off like 25 or 30 times, and after a few minutes, the car will finally start. Once it does start, I can turn it off and it WILL restart right away. I've pulled out the ignition and cleaned the contacts, but it did not really help.

Any input would be GREATLY appreciated!!!

Thanks in advance...
Joel

If you listen carefully as you insert and turn the key do you hear the theft deterrent relay ( passenger foot well ) click??

Is the car a manual or auto trans?
It's a manual, I'll check on the security light, and see if I can hear the click...
Thank You!!

check the connections at the starter.
It sounds like you have a loose connection there.
(disconnect the battery first)

Default Same here...

Hey did anyone give any solution I'm super frustrated.

I'm sure someone has come across this before, but here's what happens once in a while when I try to restart the car once it's hot, and I've already driven it for a while.

I turn the key, and the fuel pump as well as all the dash lights come on, but the starter does not turn, no sound, the car won't start.

Basics first as noted.
Does the security light stay lite, if so resistor pellet is not being read correctly
Are all battery connections good
Check the connection at the starter solenoid
If all above are good open the schematic and start reading voltages down the starting path

Check how your TDR relay behave when you start and this happens next time :
Check if the TDR get 12volt on term C2 and if A1 is grounded when you try to start .

The TDR is relay is located above the BCM , footwell on passenger side .

This purple wire on the starter solonoid is coming from the term A2 on the TDR relay .

Certainly sounds like an ignition switch issue...cycling the key most likely removed some light corrosion on the switch contacts...I went through the same thing with my ignition switch a while back...I only needed to cycle the switch 5 or 6 times until it started. Before you start the car select VOLTS on the DIC and take note of the voltage while starting...this voltage is taken from the IGN 1 circuit voltage to the IPC...I believe mine was about 8-9 volts....and as previously mentioned check both battery cables and clean them at both ends !!....and while you're down at the starter have someone crank the engine while you are probing the "S" terminal with a 12 volt test light...the light should remain BRIGHT while cranking....do the same thing probing the starter housing but connect the test light to battery negative...the test light should NOT light !!
