hi im pete ( and my wife that will usually be posting is liz)
we just did a 411 pcm swap on my 1997 chevy k1500 and after i (liz) put the new tune on the 411 pcm it started and ran ok. I went in and changed a couple things like the fans and now i cant get the truck to turn over it will crank but no start. i have now tried this on 2 different pcms and same thing. can anyone help me out because now my scanner and editor wont connect to the truck and im tired of using credits on new pcms to have the same thing happen over and over again. Thanks in advance for any and all help or ideas.
i have the pin out and its wired correctly but i dont know what else to do
