300zx wont start

[Challenger266]

I have a 1987 300zx non turbo.

Motor cranks, fuel pump runs, have fuel at fuel rail, has spark...car will run with starting fluid or dumping gas into the intake. ECU shows codes...
11,22,33,34,44,55.

I replaced the CAS and it still shows that fault.

If i turn the distributor i hear 1 injector fire. Always the same one no mater which cylinder the rotor is lined up to.

I removed the chassis ground, cleaned that up for a good strong ground. I have 0.0 ohm resistance from the cylinder head to chassis when verifying that the motor is grounded as well.

I have a new battery, gauge reads 13 volts.

Has fresh gas, when i turn the distributor to make the injector fire i can do it repeatedly to "load" the cylinders...then crank ot and it will run for a moment then die again.

My injectors are obviously not working...what are the odds all 6 go bad at once? And why is the ecu showing code 11 when i just put a new CAS in...and i did verify power. 12v to one pin, 5 to the other 3.

The wire harnesses are all intact i believe. I do see a few random plugs that i do not know where they go and can not see any sensors or components that they would plug into.

Any ideas what might keep this car from starting?

You might have a bad ecu. If the injectors and ignition trigger when you manually turn the distributor there is no reason for the car to not run unless something is out of time or you flooded the cylinders.
