Starts every time when cold.
Once driven and sitting (warm) it turns over but will not start under load (key all the way forward).
Will occasionally start when you let off the key, on that last turn of the engine.
While having this issue it will consistently start with key forward and jumped from starter relay.

I have replaced the following with NEW parts:
Complete dash harness
Both engine compartment wiring harnesses
ECM
voltage regulator
starter relay
ballast resistor
coil
cleaned all grounds

I have a new, in the box ignition switch which I can plug in and turn the car but it still won't start.

I have not replaced the distributor.
Thanks
