Default 96 C4 making me nuts

Hi
I have a 96 c4 No crank no start . there was an issue with the PCM board was burned out . replaced the unit Still no crank no start . If the starter is jumped at the solenoid it will run for a few seconds and shuts down . I have checked all the grounds on the car all look good i see no evidence of broken wires or loose grounds . No led on the dash only park light comes on . I'm in the process of checking the circuit for the starting system but defiantly frustrated.
the only light that comes on in the information center is the pass key it flashes then stops. Could this be the VAS system that is shutting it down is there a way to bypass?
thank you
tim

Use a ohms meter to read your ignition key. “ black dots on both sides of key. This will tell you if your key is “open or it will give you a resistance reading. You will need to find what resistance you’re vats is looking for. Or, Search internet for a Vats bypass. If your electronic savy ? You can save money buy buying a kit and soldiering together yourself.
