Problems with ECU

There is a constant 12volts going to the ecu. When the ignition is on is there not another wire that signals the ecu to turn the fuel pump on, ready to engage the starter, etc...
Well my computer no longer receives this signal. If anyone has time can they check the black connection number 30 on the ecu connector. I believe this wire should read 12volts with the key on.

Or if you have any other suggestions, car no longer starts primes the fuel pump or engagest the starting seliniod.

There are two +12V connections to the PCM.... one from the battery (PCM BAT) and one from the ignition switch (PCM IGN). Both have fuses. What year is your car? LT1? They are not all exactly the same. Fuse locations differ from year to year.
