Funny enough i had initially gotten an ac delco fuel pump but one of the fuel line attachments broke off when installing it. Being rather strapped for cash I opted for the cheaper option the second time and much more carefully installed it. Im getting a fuel pressure tester today to fully test the system. These engines are supposed to be at like 53 to 57 psi right? And if im getting good pressure then im probably looking at an injector issue?

 

Cleaned out the entire fuel system and replaced with new gas. Replaced all the plugs. Same problem as before. Will sputter and kind of run after priming the pump a bunch of times. Will start on ether but barely. When started idles perfectly. Bogs a tiny bit when you put you foot to the floor and then backfires through the intake. If you turn it off at operating temp and try to start it again it won’t even try in the slightest to run.

 

Here is the fuel pressure test procedure:
