RE: There are cut cables in my control unit !!!



I recall reading about cut wires somewhere... maybe in this forum over a year
ago?

Anyhow, there was a ground loop problem with the engine computer in 86 (turbo
only). The fix was to snip 1 or 2 specific ground wires. Don't reconnect them.
Sorry, but I don't have any other info about this. 

Hall sensors do die. Mine died when the car was hot.  

A friends 86 5000CS just had a similar "no_start" episode. After lots of
hairpulling, it turned out to be a bad pressure accumulator in the FUEL system.
The thing is located under the car in the rear. This keep the fuel system
pressurized.

good luck,
