What's the problem, any applicable trouble codes? Can you communicate with computer? You can check for reference voltage at any sensor that uses a ref voltage, to see if computer will do anything. You can check voltage and grounds for the computer.

I dont know what the problem is my car stoped charging I was told it was the regulator in the pcm so I changed the pcm before it would run untill the battery died now with a diffrent pcm it would run for about 3 seconds then die like it lost fire it done that a few times but now wont runn at all

Is the pcm compatible with vehicle? If this is a new pcm, I believe the dealership will have to program computer.
If it cranks good but won't start, have a helper crank it, while you visually check for spark at the plugs. Anything?
