Re: Question - Security system has killed the pip signal
If your truck is trying to start, you might want to look for the source of your problem someplace else. Unless I'm reading the schematic wrong, the security system locks out the starting system.Try checking your other fuses, there's a 20A fuse that feeds the PCM relay, it also supplies the ignition and the fuel injectors.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
