After a installing the new CPS the truck wont start at all and deciding to finally buy a multimeter, Checked the pcm main power supply and its only giving out 0.07 volts out of what I can read should be 5 volts. So i'm going to attempt to try the five volt bypass that I saw another user do. Hoping this is the issue

well idk about the 5 volt bypass I would have said the cps but my next guess is the pickup in the distributor or pcm but I do know if The administrator or Hey You says it it's true he definitely knows his stuff I've picked his brain a couple times

So I unpluged all my sensors to check them and plugged them in and now I have the code P0123 which is my tps.. Which would make sense as a faulty tps causes the literal symptoms (poor acceleration, struggle switching gears, random stalling, rough idling,) so imma be PRETTY cranky if I boned my truck over a simple faulty TPS
