86 turbo (gas) sedan injector/computer issues


Guest

Just brought her home. Not running. Auto trans. Mechanic said #1 injector stuck open, filled cylinder with gas. He replaced the injector and it was "fried" immediately. He believes computer contacts for #1 cylinder are welded together, providing constant 12 volts to that injector (no pulse).

Sounds plausible, but wanted to see what y'all think, before I start tearing things apart.

I noticed a bad ground clamp on battery neg post--could that be a factor in causing the original problem?

Where is the computer located?

Is 85 turbo gas computer same as 86? Any basic test(s) I can do to confirm that a computer is good/bad?

Thanks.

David
