So i figured out my miss fire but now my car doesnt want to idle. My wideband shows that it is leaning out and then dies. I have unplugged my maf and it ran good for a minute then died. I just put in my new fuel pump thinking that was the problem but it still continues to do it. Also i can turn my ignition off and pull the key out and the car will continue to run like s*** for a minute or so then die. My buddy and I think it might be my fuel regulator. If anyone can help me out again I would appreciate it.

Rule out the injectors first. You can OHM them as well as do the click test with the CAS. Do a search with the blinking search button to the right and try those and give us an update. And welcome to Nico!

Make sure you gapped your plugs correctly to your car.
Try to get your hands on a boost leak tester to make sure you got rid of all of the leaks.

If it runs once the key is pulled, you must have a boost timer somewhere.

So you say it runs for a while with the MAF unplugged well? Have you cleaned the maf? Did you OHM the injectors? If the car starts right up,then the regulator should be fine. If your regulator is bad, the car would lose fuel pressure while sitting because the fuel would return to the tank. Make you one of these and leave it in overnight to see if the pressure changes. http://www.nicoclub.com/archives/diy-fu ... ester.html

What should I look for to actually make my car turn off when I turn the ignition off?

Do you hear a beeping sound when you turn it off?

No it shuts off all of the power but the engine idles like everything normal.

Where are you from? Some of the true JDM 2+2 TT have turbo timers from the factory. No warnings or anything else. They usually have a box on the left side of the steering wheel on the lower section. If anything check in the ECU area, check the ECU and who programmed it, maybe there is a glitch in the system causing it to run.

I'm from the US and I just swapped over the engine into the car and used the stock wiring
