If it has a key fob,it is possible,but doubtful,the crankshaft sensor is the more likely problem.

Chevy cavalier wont start randomly! makes one click and a humm sound my lights come on the radio comes on but the car just wont start, ive had battery replaced along with the ignition switch, fuel pump,...


Ok then, from your description and the
make/model/year of the car you have there,
it appears you've reset the VATS.

The car's security immobilizer
reader at the key switch
does not recognize the coded
chip in the ignition key any longer.

You can try to put the key
in the ignition, turn to the on position &
wait at least 10 min like that.
(Do not turn off the key switch before
10 minutes as elapsed!)

Once done, the key is re-programmed and
should allow the fuel injectors to work again.
The car would start now if corrected.

In some cases, the VATS (GM'S VEHICLE ANTI THEFT SYSTEM)
will re learn the code this way, and will then
allow the restart, however if this does not work,
then you can simply tow it to any GM vehicle dealer
to have the service department re code it.

There is a permanent solution though.
Adding the PLJX Self learning Bypass module (59.95)
will bypass the PASSLOCK system in your vehicle
for good. See this at www.PASSLOCK2.com

Good luck I hope method 1 does the trick!

Here is the 30 min relearn:

Ignition keys relearn takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself.

Have 2003 chevy tahoe the security light flahs wont start


Your Passlock may need to relearn the ignition keys, if the ignition lock has gone bad like my in-laws Grand Am Gt, here is what i did so they will not get stranded any more. Buy a Passlock by pass module for around $70.00. You can orderone from GMPASSLOCK.COM in the mean time try resetting the Passlock. Good luck

2001 Buick Regal cuts off while driving at times also won't start


The ignition switch on that model is rated @ 50amps. When I was driving my 2001 Regal LS (at 120,000 miles) and used the turn signal, the engine would die, when I switched the turn signal off, the engine ran. So I replaced the ignition switch, and all is well.

Starting probles


have them check the ignition !!!

I had a 1990 Cutlass that did the same thing. It would turn over but not start when it got hot too or just cut out on me right on the road. I had it in the shop 2x's , thought it was fixed and got it out of the shop only to have it die later that night in the pitch dark. I had it towed back to the shop , they let it run , hoping it would cut out and it did. It was the ignition.. when it would overheat it would just shut off the car ... you couldn't start it peroid! Like you said 20 to 30 minutes later when it cooled down the car would start back up just fine ... then you'd drive it , it would heat back up, the car wouldn't start again for another 20 to 30 minutes !

hope that helps !

2003 saturn ion will not start somtimes


The security interlock on the ignition switch goes bad. The ignition switch needs replaced. (about $35 from the dealer) It takes about 30 minutes to replace and another 30 minutes to "learn" your key. The car locks out for 10 minutes when it fails so if you look in th emanual there is a procedure to override the lockout but it won't work for 10 minutes. Google the problem there are procedures for the switch replacement and learning the key with the new ignition switch.
