[T3] I think I found my stalling problem!

[Keith Park]

I had this happen to me 15 or 20 years ago, just died without warning coming
out of work, no fuel pressure,
Swapped brains and all was well, fixed the failed one and it was fine,
that’s when Jim told me of this problem,
Only problem ive ever had with a brain.

describe, rust of the pins due to the porous spacer.  On one the can is
actually tilted from the pin failing:

fix both (to avoid breaking anything while opening up the ECU cases), so
watch for a separate email about that soon.
