I have the same problem with my 83.5 Digijet.  My Westy is sitting dead in
the driveway with full-on injectors again about 300 miles after ECU was
rebuilt.  Could not find fault with the harness when checking for shorts
while flexing wiring.

Injectors read 8 to 10 ohms resistance.  One source listed about 16 ohms as
spec.  These are  new Bosch injectors installed last year - possibly
defective and causing the ECU components to overheat?

Looking for answers.  Any clues out there?  Eager to get my Westy
dependable for the cool Fall weather approaching but do not want to be
stranded in the back of beyond.
