my 01 s10 is having starting issues I know it isn’t the starter or the battery it’s some kind of security issue in the ignition system. I have perfect power when I turn the truck on and when I try to turn the motor over it doesn’t do anything and for the car to start I have to try to turn the key for a while and it starts when it wants to. I have job clue what it could be all of the forum pages are saying it different things. I really need some help any advice on the matter is appreciated.
