Here's my problem.
'87 Camaro 383 TPI MSD Distributor with stock external coil.
The car usually starts. On those days it doesn't here are the symptoms.
Cranks, oil pressure builds (as expected). No spark. If the scanner is attached to the ALDL, or some pressure exerted on the ALDL it starts.
I am baffled that a bad connection at the ALDL can prevent a spark. I even disconnected the computer from under the hood, and it wouldn't start.
I have no trouble codes at all.
Disconnecting the battery and waiting a minute or two doesnt do anything either. I replaced the cap/rotor and the external coil. nothing...
anybody have an idea? would appreciate it. its a fun car when it works.
