Yes the security light has a lot to do with the vehicle starting and shutting off.This means the Body Control module is not getting the correct signal from the key itself or the ignition cylinder is not reading it correctly.What you can try,and this is something simple is if you have another key use it and see if it makes a difference.Sometimes a worn out key will do this.If this makes no difference then you will need to get the codes from the Body Control module.Usually a B2960 will come up.There is a service bulletin for this.It is number 01-08-56-002A.Has to do with checking wires and connections.Using an ohm meter for checking resistance in the wiring.Also using a scan tool for looking at the data.Let me know if you have anymore questions.Good luck.

2000 gmc c6500 wont start


We have a 2000 GMC 6500 454 engine. Truck will shut off, we turn off the the ignition wait for about 4 or 5 minutes. Doing waiting time, if you turn the ignition part way on, you can't hear the fuel pump, and if you try to start, it will not start . But after the 4 or 5 minutes, when you turn the ignition part way on, you hear the fuel pump, then it will start. It will shut down with a heavy load or even with out any load. It seems to do it more often when it's really hot out. It will shut down as much as 10 times.

Honestly you should send it into the dealer. I don't think guessing will help you. Typically it is a dirty connection into the steering column (behind the ignition key) But diagnostics need to be run and a look at the VSS system (through a good scan tool) is needed to confirm.

The 96 park avenue will start great and run great. No security light comes on and everything runs smooth. No bucking or hesitation. A great ride. Then all of a sudden it will die. Lights stay on and radio...


It cannot be the VATS system. The TDM, that is the core of the VATS system, is engaged only at the time you start your car. I have a problem exactly like yours on my 95 LeSabre and just discovered it is the alternator that sometimes charges and sometimes doesn't and when it doesn't, the battery's voltage goes lower than a certain threshold and the computer (PCM) is unable to work anymore and shuts down the engine. Took me months to discover this!

Key stuck in ignition


Be sure its all the way in park or try neutral.Its possible that security system does not recognize the key. Is security light flashing or on steady? Shut all doors and windows,trunk,hood, turn off all accessory's,roll down drivers window, turn key off and remove for at least 1 minute, insert key into ignition, try to start leaving key to run position for 20 minutes, turn key to off,wait 15 seconds, try to start again leaving key to run, wait 20 minutes, turn key off,wait 15 seconds, try to start, again leaving key to run, wait 20 minutes, turn key off, wait 15 seconds, try to start. This should relearn key code. It may relearn after 1 learn cycle and start if system is ok. Hope this helps and that the weather is dry and warm for this procedure! This is not always a fix, but works most of the time.

Theft system 2000 malibu ls


try this: turn key on, crank starter for 1 second, leave key on for 10 minutes. after 10 min. shut key off and repeat 3 times. (on second try, crank a sec. or so longer, the reprogram may take off right away. if not, repeat make sure battery is strong, key could be on for 1/2 hr. sometimes engaging emergency brake before key is turned on prevent daytime running lites to come on to save battery power (if equipped). been through it, thought i'd mention it

Engine rotates but will not start. I have spark and can hear the fuel pump relay click, but I don't know if the fuel pump is working. T in Georgia


the only method that work was pulling the fuel pump fuse,wait 1 minute, crank her with out your foot being on the gas for 15 sec. Put the fuse back in , and start her up normaly. 1 st attempt she started but cut off, redid the process over , got in started her up normally, but had my foot 1/4 way down on the acclerator. She started and feathered the gas til she was fully operational. Let her stay on for about 10 minutes then took her out for a good long spirited drive.smile.gif
