Changed it a week ago it's brand new

Did you check fuel pressure?

Maybe a bad ECU, or a badly programmed chip? Do you have access to another ECU?

Yes I have 2 ECU and still same thing I'm like going to throw it off a cliff already

Yes I have fuel pressure as well

UPDATE !
So it now starts but ONLY when it's cold then idles for a bit then starts to die then it will only crank. Then I let it sit for a bit and then turns on but rough idle then when about to get warm it does again any thoughts

check your fitv and iacv
check your timing

How did you verify it

Timing is on point and fitv and iacv are good as well ordered a new engine harness as my connections for the coolant temp have been repaired several times

Fuel pressure tester by just taking it off the filter and turning the key on and gas was coming out.
Also I've repaired my engine harness coolant connectors serveral times maybe that's the problem as it has repairs maybe connection is bad from so much repairing it? Think so?

Can you post a pic of the coolant connectors? I'm guessing you mean the grounds that are on the thermostat housing? If those are messed up, then they will definitely keep the engine from starting.

If you can get the car to start up and then it eventually dies it's probably not those grounds. Like I said I would like to see the fuel pressure as an actual psi reading from start to finish. I think you have something going on there.

Hey guys got a UPDATE
Well I got a chance to work on it again as I got into a motorcycle accident .
So what I did was change my IACV and map and TPS from another car and it can wayyyyy better it actually idles and stays on. But after a few min on start up it then idles really low.

Check for vacuum leaks and adjust the idle screw out to increase idle.

Edit:Be sure to jump the 2-Pin connector by the ecu (Same one used to pull codes via CEL) when adjusting idle (or timing), or else it won't work.

My 92 eg is doing the exact same thing. I even have the identical circumstances of a brand new motor, fuel pump, filter, tps, map yada yada yada. I am down to purchasing a new distributor. I put a spark tester on mine and was getting weak and intermittent spark.
