* Ill add this too, If the car is cranking and not firing, its Ignition or fuel related. If you feel that the wiring is NOT an issue. Then you need to check the mechanical aspect. Like fuel pressure, make sure its putting out at least 41psi. Pull out a coil pack and a plug, put the plug into the coil pack boot and let the spark plug contact touch the block (creating a ground, or complete circuit). If you have proper fuel pressure and spark, then get a Nod light kit and check that the injectors are firing/opening.
If the issue isnt found in one or more of those components, you have a nightmare on youre hands and it wont be fun.
