Pontiac Repair Questions? Ask a Mechanic for Answers ASAP
theft sys light on solid ive tried the relearn procedure as well as the 10 minute wait thing, the light IS NOT flashing it stays on constantly and will not turn off, recently had new fuel pump, and fuel pressure regulator installed as the car had sat for around 6 months. Also I would like to know what Fuse is responsible for the theft system so I could check that.
it did the first time so i could tell there was just enough fuel in the injectors to go for a second and then it cut out, now it will crank and everything but its not getting any fuel, so it wont turn on now, i can hear the fuel pump working. Im pretty sure it has to be that theft system.
ok let me know on the injector pulse
one terminal should be 12 volts and the other should blink a ground when cranking it over
actually the dash cluster itself is the theft module and if the cluster is lighting up and the gauges working the cluster has power and ground to operate
if it does not have the ground blinking at the injectors and the theft light is on then either the pass lock sensor is bad in the ignition lock case or the dash cluster itself is bad those are the only two things that will cause a theft lock out of the fuel pulse to the injectors
which the terminal testing for the power or the blinking ground ?
lets see if another expert can help you im missing something here
hang on another expert will reply back to you hang on
You are indeed having a problem affecting your factory security system. Your car has a factory security system called Passlock. It is a fairly sophisticated system, involving several electronic components in the car. Basically, it works like this: Your ignition lock housing contains a signal generator; when you turn the key it sends out a signal over the car's computer network. The signal is received by an electronic module (in your case I believe the body controller is the module involved, but on some models the instrument cluster contains electronics that perform this function). The body controller compares the signal it received to one that was programmed into it's memory previously. If the signals match, the body controller sends out another signal over the network that is received by the car's powertrain control module. When the PCm receives this "start enable" message it then allows operation of the fuel injectors so the engine will start. If anything at all goes wrong in this sequence of events the result is that the fuel injectors will not operate and the engine will not start for at least 10 minutes. If the fault occurs three times in a row, the fuel injectors are locked out for 30 minutes before any start attempt can be successful. This is not something you can diagnose or repair yourself at home. To diagnose the problem requires a Tech-2, which is the factory GM scan tool and the only one that can access the security features in the car's electronic modules. All GM dealerships and many independent shops have this equipment, and can easily diagnose and repair this problem for you. passlock faults are pretty common on GM vehicles as they get older, so most GM dealerships stock parts for quick repairs. I am afraid you will need to take this in to your mechanic to be diagnosed. There are many things you can still fix at home with basic tools, but unfortunately this is not one of them.
well thats what i was afraid of but thank you for the explanation one last thing I dont know if you can give me this kind of advice but I think I am going to attempt the product from this site. http://newrockies.com/ it seems like it may solve this problem with whatever i could be having with this particular issue. luckily for me I have a certified GM mechanic in the family so he will install it.
