Car will not crank. I have replaced ignition coil three times, replaced spark plugs and wires, crankshaft position sensor and ECM. It has a good battery. I am running out of ideas.

Have you tested to see if you are getting fuel? Take a can of engine starting spray and shoot some into the intake behind the air cleaner. If it tries to start you have spark but no fuel. Is the CEL on? What did it do before it would not start?

I am getting fuel. I checked that. I am even getting fire from the plug that hooks into the ignition coil. I have replaced it three times, although I have not replaced it since I replaced the ECM.

Well you need three things, Fuel, compression and properly timed spark. You have fuel. Your seeing spark. What is the compression like and is the spark in time?
