That's not what I asked you.
What was the fuel pressure? Did it have injector pulse, Did it have spark at the plugs?

Check for power at one side of the injector plugs and one side of the coil plugs with the key on and let me know what you find.

It has a problem with the crank sensor circuit. That may or may not be due to a bad sensor. It can also be any of the related wiring. Your going to have to test all the wiring and the sensor.
Here is the wiring diagram

Well, I suggest you check it again. Your computer is not calculating a reference signal and if your 100% sure there is nothing wrong with the circuit, then replace the computer but if it doesn't work, that means you missed the problem in the circuit and wasted a bunch of money.

Then check all you power and ground inputs at the computer plug before you replace it.
