Cadillac Repair: Car wont crank, correct fuel, firing order


Question
I've changed timing belt, map sensor, new computer, spark plugs, wires, check compression, throttle body, and the fuel regulator. What do I need to do to get my car to crank? It turns over like it wants to but it doesnt, and it is firing.

Answer
What model and year and what was the reason of changing all these components? Starting from the basics, make sure the batteries charged, firing order is correct, fuel pump for function, grounds on ignition components. Also when you say its firing can you hear any combustion? if so check your timing.
