Exclamation 94 ls400 still doesnt run

Im back on here once again to say my car still doesnt run and i feel like im just about out of options.

Last time it was clear the ECU needed be repaired.
So i had the ECU repaired by a experienced person who repairs ECU's ect. For Lexus.

At start up the car definitely had more want to come on and stay running but still sounds like only one side of the motor is firing. What could possibly cause this???

I had the igniter modules tested at an auto parts store and all of them passed, the coils im using are within spec. I have new plug wires, caps and rotors and spark plugs.

I cant figure out the problem, please help!

It really is best to spend a little money diagnosing a car and not just throw parts at it.

Any check engine codes?

The car has needed everything ive put on it, how do i figure this? By diagnosing that theres a problem with the part.
Again a list of everything thats been replaced
Spark plugs
Spark plug wires
Distributor caps and rotors
Ignition coils
Igniter modules
ECU (repaired)

Only thing i can think of, im not 100% sure that fuctions is crankshaft position sensor.
No i havent checked if i had any engine codes yet with the new ECU.

Start with the checking for codes. At least this often points in the right direction.

I will check them as soon as i can. Now does have a code for if the crank sensor is not functioning? This is my bet that itll be bad, at least im hoping for something being bad at this point.
