i got an 2004 pontiac grand prix gt with a z7 turbo kit on it. anyways my timing chain snapped due to rubbing on the timing cover. not sure if the person who put the car together before i owned it used a machined cover so i bought a new one and double gasketed it. My battery went dead while working on the car and now that its all ut back together it wont start. I have spark and it cranks great but my injectors arent spraying. I have a service theft system light on the dash that i have never seen before. I have tryed the procedure on here to reset the security on here twice with no luck what could be killing my injectors? i need to get this thing running. yes all the sensors cam and crank and oil pressure were plugged back in. please help thanks

You shouldn't have left the battery hooked up while working on the car. If something electrical happened, it could have fried your pcm.

But that's worst case scenario, do you hear your fuel pump prime when you turn your key to ign? Are your spark plug wires on secure? Is your MAF plugged in securely? Is your Crank Postion Sensor connected securely?
