1995 Chevrolet Truck Repair Question
What will make my computer read no power going to it?
There has to be an open circuit between where you plug in and the PCM. Check wiring harness at PCM for corrosion,something loose, pushed in pins. Also, check IAC for idle issues.

hello i checked all my connections to the pcm and everything is fine no corrosion no pushed in pins and all the connectons were tight is there anything else that would make it read there is no power going to the pcm
Where are you getting this information?
What is the code number/s you are seeing?
Your truck doesn't have a carb.
12 is the code #
There is no code 12. You always get that code before it reads the real codes stored.
it will run idling but when i put it in gear it idles down and shuts off it is a manual trans
First pull the EGR off and make sure it's not stuck open. At this point you could have issues with the throttle body, IAC, or many other things, especially since you have taken it apart now. You're not going to find this problem with a paper clip. That OBD1 system tracks only a fraction of what the newer computers track.
when i took the throttle body off and cleaned everything i got new gaskets put it all back together and it ran better but i descovered the problem was the cold start censor and i replaced it then it wouldn't run right again i adjusted the timing and still the same problem the egr isn't stuck open any more suggestions
do you think it could be the coil or the distributer cap
There is no such thing as a "cold start sensor" so I don't know what you changed. It's probably time for a professional diagnosis.
