With the key Off, cluster is dead. With key in ON position, I am getting some noises from glove box area.
With key turned to START, everything goes dead. Then turn key to OFF, wait 5-10 minutes, turn key to ON, then I jumpstart under the hood using jumper wire from battery to the purple wire, the starter activates and cranks engine properly, and engine will fire and sometimes tries to run for 3-4 seconds while starter still engaged, but then quits firing before I remove jumper wire. I wait a few seconds, and try the jumper again and engine cranks over freely but will not fire. I then turn key to OFF position and wait 5-10 minutes, then begin process again with same results: engine fires good on first 5 seconds of jump starting, then no more firing until a 10 min wait.

This is always on cold engine as car has not run in months.
I have a 1990 FSM, but last night I discovered that section 8A is missing from manual, that is the Electrical Trouble Shooting section that I need. My understanding is that is a separate booklet, I bought my FSM for $100 from Craig's list.

As far as I understand, the VATS is bypassed as I have a VATS INTERAGATOR hooked up to the wires at the base of steering column.
I have also swapped ECM from my other zr1, nothing changes.
