Ok, well this is my situation in a nutshell. I had converted my car to a Hahn stage V turbo system and many other things such as the OTTP return style fuel system and now I am converting it all back to stock. I have everything done now and reinstalled and my car will NOT fire. It turns over fine and at some points it tries to start but very few and far between. I have a licensed mechanic helping me out to figure this issue but we are at a road block. I will list all the things that have been tested for any of you that are interested;

-All coil packs are good
-We are getting good spark
-We are getting fuel to and through the injectors
-Throttle body is functioning correctly
-We are not tripping any codes
-Voltage is good everywhere
-Grounds are perfect everywhere
-Timing is dead on
-Cam position sensor is set correctly

Things we are leaning towards;

-Crank sensor??? We are getting voltage to the sensor and the sensor is reading around 900 Ohms(Not sure if this is within spec but I dont know what specs are for this sensor)

-Hptuners tune for when I was turbo'd is still on the car(I cannot get the car to a GM dealer to reflash stock tune and no longer own hptuners. I dont think this would cause a "No Start" but who the f knows right about now)

 

If you have the stock injectors in, with hahns tune... Im not sure if it would start either...

 

um turbo set up on all sc stock stuff. maybe idk my car started with a STOCK tune on turbo set up and 80lbs so all depends
