This is a stupid question: Did you prime the pump before trying to crank the engine?

Here's my suggestion before you go any further: Disconnect your supply line in the engine bay and pump out what you can into a fuel container and set that aside. Then add a few gallons of fresh premium fuel, prime the pump by turning the key to the ON position then back to OFF about 10 times and then try starting again.

Did you ever try swapping the low voltage sides of your ignition coils?

How about your injector connectors, could they be accidentally swapped causing them to inject at the incorrect times?

What gets me is that when you try spraying starting fluid in the intake, it doesn't even fire then, and you say you have good compression. If you have fuel, air, compression and spark then you should get an explosion. That's the four main requirements right there. It still sounds to me like your ignition timing is off as If you're firing on the exhaust stroke.

Okay so tell me what y’all think. I took my air intake off the car and sprayed starter fluid at throttle body. Had my girlfriend crank the car and it literally shot fire straight out! Super wild! So I got to thinking is there anyway possible I put the heads on backwards??? Would that even work?? I followed this guide to the absolute T! https://static.nhtsa.gov/odi/tsbs/20...87902-5448.pdf Not once, not twice, but three times! I know there is no way in hell I installed it incorrectly unless I’m 360 out some how... but how would I even know I was 360 out?? I did timing and cranked the crank a million times never once got outta line or anything. So honestly could I have put the heads on wrong? Is that even possible?? Or am I just tripping?? What’s y’all’s input....
