1997 Acura CL 2.2, car cranks but will not start, does not have spark. When trying to start the D4 light will blink. Have changed fuel pump, distribitor, injector relay, computer, ignition relay under dash and car will still not start. Does have injector pulse but will run when spray starting fluid in throttle body. Any other ideas or suggestions?

You have injector pulse and it wont run? Wierd. If it runs on carb cleaner through t. Body, this leads me to believe your injectors have failed. Ohm test them. Over time, they will break down. I cannot find any specs of what they should be. But, you may find they are all they same, or one may be completely different from the others. Start here. Also, I know you replaced fuel pump, so im assuming it works. Have you verified fuel pressure to the fuel rail? I dont want to jump to conclusions, but even with weak injectors, it should atleast start.

Ok, here im at at a loss. Its possible your pcm failed. Your injectors recieve pulse from your pcm. Your pcm takes other sensor inputs, and then "outputs" your injector pulse. Short, or long depending on fuel needs. This is extremely difficult to walk you through the diag involved online. I dont want to tell you to bring it to a garage, but in this instance, it may be adviseable. Without this car in front of me, and certain test equipment, its difficult.
