Ok here is my problem engine wont start randomly only when cold. If it doesn't start first turn of key usually does then cranks cranks cranks. If I crank It too long when I let go of the key it backfires out exhaust. then It wont go.
If i put gas pedal to floor wont clear flood start up Does the supercharger make it backfire?
Ok If I pull the plugs put in new ones (Autolite 104's) fires right up. Ok last set plugs lasted a month .....so HELP
Ok little background L67 is in a Fiero with manual 5 speed. Factory manifolds and manifold connector to 2.5 inch exhaust and muffler. Has k&n air filter right on throttle body is that ok? Has zzp 3.4 supercharger pulley.
I'm running the autolite 104 copper plugs.......should I be using factory plugs? might try that next
The PCM is tuned by Ryan from Sinister mail order tune kinda thing Wondering if it gets too much fuel on initial key on pulse?
Have factory ignition module with the grey backed coils( blue backed ones are better from what i have read)new stock wires
Always starts when warm got an aluminum rad runs cool on the gauge
for the modded guys do you have problems with flooding like me?
recommend a different plug?
hope you all followed my train of thought trying to give as much info as possible
