You need to check the basics...fuel, spark. Make sure you have that first.

i have not done a leak down test yet since i do not own a compressor
ive checked and i do have spark, not sure how to check for fuel though. other than hearing the fuel pump prime and having the fuel lines hooked up correctly and fuel running through them, idk how to check the individual injectors. Ive tried turning the car on without spark plug wires and smelled the plugs and all 4 smelled like gas. so im guessing i have fuel.
