Car cranks but won't start

[Motor_City_MUSCLE]

Help! I have 1995 GT. Prior to upgrading the throttle body and cold air intake, car started fine. After installing SR 75mm throttle body and SR cold air intake the car cranks but doesn’t turn over. Does a bigger throttle body require a tune. Nowhere on American Muscle did it say it was required. I watched the YouTube video of this exact unit and they never mention it being required either.

I did the following…
- set the TPS to 0.818 (range 0.75-0.98)
- checked the throttle body with peddle to the floor before installing the cold air intake
- disconnected the battery for 30 min
- checked air intake connections
- checked throttle body connections
- checked battery

No, you can do heads, cam, intake, and throttle body and not require a tune to run.

Scroll all the way down to “Trouble Shooting” and select “Cranks but No Start Checklist - jrichker”

That is what most consider to be the Holy Grail of check lists for that conduction and it has fixed a lot of cars.

The 94/95 cars a a little different so pay attention to the 94/95 specifics.
