ok guys i checked everything, swapped pcm's and nothing...still no spark, i ran electrical diags and i have power but nothing more.

Question: what would happen if i swapped ignition modules from an '86-'87 and didnt convert the plug on my '84???? just a straight swap module for module...would it burn something???

your cam sensor cap might be bad. i have the same problem, and ive change the crank sensor and got spark but only when i bypass the cam and jump it thru the crank connector.
