you went nuts lol opti has to be delco or delphi wires might have to to.
check 2 ignition fuses
stick to basics pull a plug number 2nd plug on right put wire on it vise grips it to good ground and crank it
spark or no spark bright or weak
actually pour a quarter cup of gas in funnel into throttle body and crank .
if it fires you got fuel problem
if not try step one then check power at fuses
turn key on does tac turn when cranked thats crank signal
only heard of ws6 formulas and fire hawks
Trans am is the name of grand touring race lol
Its a Fire Bird GT is a ford term
check ohms on batteriy cables
ground on block near starter
ground driverside front of head

I stand corrected

• Trans Am GT (1994) (additional luxury features such as leather seats; regular Trans Am, but with all the options including "up-level" rear spoiler and GS-C tires coming standard on the car. All 1993 Trans Ams had the GT treatment as standard, but they were not referred to as GTs. In 1995 and after, the treatment got broken down into a number of options like on the Formula)

They shoulda CALLED IT A FORMULA 1
