truck will fire up and run at a high idle for lets say a minute or so . After that short period of time it ˟˟˟˟s down like you flipped a switch. With the key in the on position you can hear the injectors clicking and the occasional electric arc in the distributor. All while the engine if off and just the key in on.

Key in Accessories? or Ignition On?
If Ignition on and injectors are clicking:
1) The wiring on the ground side of the injectors (In red below...) could be shorting to ground, OR
2) The ECU is bad and is connecting the ground side to ground when when it's not supposed to
My guess and hope is just (1). Inspect your wiring.
To eliminate doubt on (2) Disconnect pins #20 (Wht) and #10 (Wht-Red) from ECU connector and see if the clicking persists when IG is on.
Thanks for the input guys . I opened the ecu and found whats pictured below . Appears a capacitor has burn up on the board so its gonna need ecu work regardless
That looks like some traces burned up as well. I would check for any shorts in the wiring or any fuses that are bypassed, or larger than they are supposed to be before sticking another one in its place.
Label is gone off ecm. Toyota run the vin and said it should have a 89661-35850 in it . Local computer shop had a capacitor . Gonna clean it up a bit and give it a try
