Turn key to off, then start engine. The belt tensioner is a spring loaded pulley located below the alternator. I finally disabled mine by cutting the yellow wire behind the radio. It takes 30… You have to put the key into the on position. I included the actual photos that I used to gain access to my ignition lock cylinder wiring.
I thought of getting used but was advised on keeping same part numbers and used may differ or be bad also being the year and mileage. So i was just curious if anyone has ever had this problem. It takes 30 minutes and 15 seconds to reset the antitheft in a Jimmy. The first thing I would do is check the battery. The Theft deterent may be cause by a faulty theft module not reading the key. I have bypassed many of these systems by introducing the proper resistance into the yellow wire going to theft module equal to key resistor. Essentially, the theft-deterrent system goes offline and the engine will start and run with any key that turns the lock.
Using distilled water will help keep minerals and deposits from forming in you cooling system. I wonï¿½t go into the argument as to which one is better, I will just say they donï¿½t intermix. Do not insert key at this stage. Post back if this works, If not there are other ways. Insert resistance that ohmmeter read with key in lock cyl. . Leave the tool in place for reinstallation of the belt later.
The computer chip wears out etc. Reinstall the serpentine belt, following the routing decal mentioned earlier and using the belt tensioner tool. Turned over engine, it died, left key in on position, anti theft light blinked for 10 minutes then went solid, turned key to off position, counted to 7 mississippi, restarted engine, it fired and ran and anti theft light gone. Check out this video as well Please let us know what happens. Then install the bolts and tighten them evenly.
You will see anti-theft system flashing. Have a battery jumper box attached to the battery. Repeat this procedure 3 times for a total of 30 minutes and on the 4th try the car will start. Cheers Thank you for getting back to me so quickly. It sounds like you may have a bad ignition switch. Below you will find a thread and some supporting evidence of why this bypass actually works.
The car will then restart. There is a 30-minute programming procedure that does not require a scan tool. Keep wire length to a minimum. The early systems used the first generation PassKey system. In this case the Module enters and remains in a mode which allows the engine to be started and run without reading the resistance chip. I think it is ridiculous that I was never provided with the security code to my own car stereo just in case I ever had to reset it.

If the light stop flashing or goes out, turn key off and wait 2 minutes and then start engine, if your problems persists, it must be either your ignition switch, your control panel or your antitheft module. Anyone have the name of a person who can be contacted about this fix. Route modification wires clear of moving parts. Try the programming procedure again.
The sensor sends this voltage signal to the Body Control Module where it is compared to a stored value. This seems to be a problem with people installing auto-start systems. Then connect an ohmmeter to that electrical connector and insert the key. Put the key in the ignitiion and attempt to start. Remove the serpentine belt with a bel … t tensioner tool. Then install the bolts and tighten them evenly.
Doing a full reset of the anti-theft system. The magnet produces a unique voltage when it passes over the sensor. I am also going to try charging the battery, maybe there isn't enough juice getting to the starter. All I need to do is flip a switch to break the circuit again while the car is running to take the passlock system offline. I called Chevy and they told me this was the only way I could resolve the problem.
