[T3] Fuel Injectors always on


Hi folks,

I need your help with a fuel injection diagnosis.

My '68 squareback engine quit while driving and will
not restart.
Initial diagnosis revealed ignition OK, fuel injectors
pumping fuel, but it looks like way too much, and
engine becomes flooded.

I measured the signal going to one of the injectors
with an oscilloscope while cranking the engine, and
found a constant 12V, not a tens of milliseconds
pulse.
The fuel flow from the injector also appears constant,
not pulsing.

All of the sensors (pressure, temperature, throttle
switch, distributor contacts) give proper readings
when measured at the ECU/computer connector.

This suggests to me a problem in the ECU (bad
transistor??) but what I've read says that ECU failure
is fairly rare.

So I have two questions:

1) does this problem sound familiar to anyone?

2) does anyone have a working or suspected good
ECU/computer/brain box for a '68 or '69 that they
would
like to sell?

Thanks in advance,

Todd Heimer
