    I have already replaced the key switch with the anti -theft sensor the fuel filter is new.

    Today the car wouldnt stay running & the anti-theft light was fashing. I read on line 6mths ago how to reset the anti theft system. Turn the key on but not to the start position leave it on for 10 to 15 min. then turn the key to the off position then back to the on position if the anti -theft light quits flashing try to start when I do this process it will start & run & may not give any problems for days. I have notice if I dont start it for a couple of days I always have to do the procedure to reset the anti-theft system. but if I start everyday it will start & die once maybe twice then it runs. Could the anti-theft be losing sigal or voltage from the battery or some sensor ?

Hello and welcome to FixYa!,

It sounds like there is a Bad Spark Plug installed- But also check that the Fuel Filter is not dirty and replace it.

Also check the Terminal Connections to the Battery and that no Fuses have blown in the Fuse Box!

Hope this works --P3NGYJ03

    Also you can :



    1. Attempt to start the car, let it stall, but DO NOT turn the key off! Leave it in RUN.
    2. Wait 10 minutes or until the Theft Sys light glows steady instead of blinking.
    3. Do not turn the key off, but start it immediately.
    4. This should reset your Passlock system



    Thanks

    Hi!

    The injector pulse is what will activate the injectors to inject. If you have a LED or a noide light you can check it by connecting from one wire to the other and see if it blinks. Being that the security light is on, I would say that the injector pulse will most likley not be there, that is why it will seem to start for a second and then shut off.

    Ask for any clarifications

99 explorer alarm disables. Motor dies


Anti-theft system can keep vehicle from starting , Alarm is for vehicle content theft , open door without key alarm sounds (horns) ! PATS - passive anti theft system PATS enables and disables the engine from starting ,it will not cause the engine to die ! You have some other kind of problem ! If the vehicle engine doesn't turn over an red light on top of dash flashes fast ,then you have anti-theft system problem !
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.

Okay two weeks ago I was inquiring about a 1996 pontiac grand-am, this car is in overall excellent condition from the ground up. It still is faulty in the anti-theft module or circuit though, when i


Resetting is a temporary fix to a larger problem. A 96 grand am runs the Vats system. These systems do not relearn the key or ignition. They use that "chip" in the key shaft. So the fact that the "reset" temporarily fixes the problem leads to one thing. A failed theft deterrent module. (TDM) In order to fix this problem, you will need to replace the TDM or bypass the system entirely. I would lean toward bypassing the system. That way you never need to worry about it again, can be done yourself, and for cheaper than a TDM. Go to this link and look under PERMANENT FIX.

96 grand am starts for 1-2 seconds and then dies- restart in a few seconds for another 1-2 seconds; new tank and fuel pump


did you change the fuel at the same time as the pump replacement.are you losing fuel pressure/volume that was checked with a gage(have seen it happen with a new pump).does your car have anti-theft on it,it could have set and not allowing the car to start and run.

My mechanic says that the reason why my 1997 jeep grand cherokee will start an stay on for only 10 seconds is because i need to have the dealership unlock the anti theft system


I find that to be doubtful but would contact the dealer about how exactly that antitheft system works. In most antitheft systems the vehicle will start at all, or even turn over like it may try to start. If it runs but dies out I would be looking at something more like vacuum leaks, timing, idle air control or possibly the alternator though that seems unlikely.

Won't start and the anti theft light coms on. I been to the gm dealer 3 times after running a diagnostics on it still can,t find the problem. sometimes the engine will start and the anti theft light comes...


Thanks for choosing FixYa and welcome to the site. Did GM reset the anti theft system in your car? If it is going off, it will cause the car to not start.

My dodge carvan won't start after 3 attempts. it will run and then die. the alarm system will then light up. does someone have a quick fix


Put key in ignition (do not start) for EXACTLY 10 minutes. As SOON as the anti-theft lights shuts off, IMMEDIATELY start van.

This is a very common problem in GM vehicles.

There is a Passlock or Passlock2 anti-theft system. You can buy a bypass kit with instructions for it.

Trouble starting once in awhile


it does sound like the anti-theft system. There are only 2 ways to bypass your problem. 1) disconnect the anti-theft system which runs into your ignition, cut the wires to the system and join them back together without hooking it back up to the anti-theft. 2) Bring it back to the dealer so that they can replace your anti-theft sensor. The part is rather cheap but the labor is the killer.

No power in any systems - anti theft?? How do you reset?


no power usually suggest battery fuse or wiring. anti theft keeps the car from starting but may have also killed the battery. check the battery
