'14 FRS cranks but won't turn over
 

So recently installed radium fuel rails, 300c fuel pump, 900cc fuel injectors, not turbo yet but preemptive for when I do get boosted. Also put on a flex fuel kit and got a delicious tuning ecutek. After all of this was installed there was a couple leaks on the passenger side fuel rail so got that patched up and started it. Got a little bit of white smoke and it stalled out. Started up again but would only run with my foot on the pedal. Recieved a base tune for the flex kit car would not run. Tuner told me to take the fuel injectors & pump out and put the stock back in. Did that and now the car cranks but won't turn over. Ecutek dtcs says no flags. The battery is brand new, no leaks that I can see, and all fuses have been checked. Anybody have any idea where the problem might be?

Your "tuner" is probably the issue.
I would revisit the tune before looking for hardware problems.

It was actually two seals and a hose issue. Just went back through double checking everything I did & all connections. She's running good now.

cranks = turn over

turn over < fires < starts

Excellent!
Still have an issue with a tuner that says "Put it back to stock" though. The whole point of having a tuner is to not be stock.
