I cannot retrieve any codes from the computer. Engine was running fine and started to miss. I did not get a check engine light but I connected my code reader and did not get any response from the control module. The code reader works fine on my other vehicle.
Do you
have the same problem?

With the standard obd11 datalink connector, pin 16 is battery voltage, hot all the time. Pins 4 & 5 are grounds. Are you using an obd11 code reader? If your missing voltage on pin 16, maybe we can track it down?

How long since a tune-up, have you done any basic testing? Check for spark at the plugs, check fuel pressure?
