yeah sorry..... it was a 0017 code.... misfire cyl #1
i swapped injectors around and that was it so new injectors runs great!!!
then I had the crank cam code again, turns out i was off on installing the exh. cam sprocket, re-did that and got a too rich code did a throttle relearn, now ZERO CODES but...
when it sits not running for more than a minute or two, upon starting, I have to crank it longer 5-6-7 rotations... it NEVER did this until now, always started on the first turn... weird.

so now that's the only thing left to solve, bestow your knowledge upon me!

EVAP purge valve.
Or fuel pump.

You shouldn't hold the key in the start position. Just turn it to start and then release the key. It will crank until it starts or times out.

P0017 was the code that was telling you and everyone else that the exhaust cam sprocket was mistimed.

You only need to turn the key momentarily. Doing so initiates the start sequence and it will crank until it starts... or doesn't. What injectors did you use? Any smoke or sputtering at startup? You could monitor the a/f once the car warms a bit with a scan tool to see what's going on. Look at short and long term trim. The long start could clear up after a few run cycles.

What spark plugs are in it, brand and exact p/n? Keep checking for codes, even if no CEL.

Ok so now hard to start after sitting 5 minutes,
fuel pressure test: key on 55lbs, running 55-60lbs doesn’t dip under throttle, key off pressure decreases slowly to zero in about 5 minutes, leaky injectors? They are new but china/Amazon ….

On startup slight sputter then runs fine , no smoke

today YouTube certified mechanic videos told me I should be able to blow through the evap solenoid, well I can’t blew blow through the new one either but it has a new one. It was cheap, but not China cheap. I got it at O’Reilly’s.

Your certified mechanic lied to you. They are normally closed.

Does it start hard and smell of gas after sitting for 5 minutes? If not, then the fuel is leaking back into the tank through a bad valve in the pump.

P0017 is not defined as misfire, it is defined as timing chain problem. Whoever you are getting info from is a dummy.
P0301 would be misfire cylinder 1.

Test the fuel pump. After it turns off watch the gauge for 10 minutes looking for the pressure to drop if it goes to 0 in less than 10 minutes you need a new pump. There is supposed to be a check valve that keeps the rail primed.
