All injectors have the same pressure supplied to them. Comes from the fuel pump and the fuel pressure regulators.
If one injector seems to be "injecting" too much gas, then it is the injector or the o-rings.
However, just one or two, maybe 3 bad injectors won't stop the engine from starting. There may be other problems also.

The crankshaft sensor and the camshaft sensor systems are different between the 3.0 and 3.5 engines so the ECU isn't getting the signals it wants.
But the original ECU not running the fuel pump is very unusual, although possible. Did you get the original ECU?
Why was all the other work done? Was this done trying to get the car to start befor aor after the ECU swap?

It sounds like the car may have a bad IACV (Intake Air Control Valve) and this has a tendency to short out integrated circuits in the ECU.
But you have to get a 2000 ECU for you car - PERIOD. No ifs ands or buts.
And before you hook up the 2000 ECU test out the IACV as outlined in the service manual on pages 502 and 506 in the link below.

You can't run an 03 ECU on your 00 Max and expect everything to run right. Get the proper 00 ECU. This should be the very first thing you do.

My lights go off when I turn the engine off. The key can still be in the ignition switch.
This may be another symptom of the wrong ECU. The body control module, SECU, is different in the 2000 & 2001 than what is in the 2002 & 2003.

Wait until you get the correct ECU in the car and see what happens. Having 2 mis-matched computers (the ECU and the SECU) trying to communicate with each other can cause unpredictable things.

OP, you really need to follow our simple advise rather than making things more complicated
