2005 Chevy Colorado anti theft My truck shows the anti theft light on and it will not crank, how do I reset the computer?


There is no magical reset procedure , you have it scanned for DTC'S -diagnostic trouble codes ! Then tested and repaired . Which means you have to take your vehicle to a qualified repair shop .

I got a 1998 Mazda b2500 it will not start , it has two wires ran from the starter to the inside of the truck , , so I don't know if the starter is bad or the wires are bad or if it is the solenoid?


The B2500 was available with manual or automatic transmission and with or without anti-theft. The two wires probably were intended to bypass some part of the starting circuit, possibly anti-theft.

You cant. The key needs to be programmed to the car. You may have to have a locksmith or dealer do it as it may require a special computer to do

flat battery , causing the anti theft system to cut in would be my first guess, when changing the battery make sure at least one door is open as when reconnecting new battery the anti theft will most likely lock the vehicle

I have an isuzu truck and i was told that the anti-theft system is not allowing the truck to start.. HELP


You didnt specify what year and model the truck was, but generally speaking, the factory anti theft systems can be disabled. On newer trucks, a scan tool can be used, others require a certain procedure to disable it.
The other question is, who told you the anti theft system is to blame, and how do they know?

Truck wont crank each time


It sounds to me like that you have several different issues with you vech and on the pass lock system will not cause all the problems listed how ever it will cause the no crank and after five min or 30 min start it is most likely the pass lock sensor unless your truck has a pk3 system (the key will have a + or pk3 stamped on it)If it is a pk3 system then it may be the theft detturent module if ton a pk3 system then most likely a pass lock sensor . Take the vech to some one that can ck for codes and find out all the codes set in the vech. This will tell a whole lot about what is going on with the vech .Im not very good on drivabilty problems. The evap leak and the mis fire will not be related to the pass lock problem.

I can't get my truck to start because of the anti-theft lock.


One way I have found to fix that is to by-pass it. You might check your fuses and the little anti theft key under the steering wheel first though. Hope that helps.
