I had a new fuel pump put in becuase it was having a hard time starting in the morning. So the day after i had it changed it wouldnt start for a few hours but once it started i brought it to my mechanic they checked the fuel pressure and it was only putting out 50psi, its suppose to be 60-66 so idk whats going on, any ideas?

I agree with djlove. It could be a bad pressure regulator as well. At any rate, they should at least diagnose it for you since you just had work done on the fuel system.

I'd wonder if when replacing the pump/strainer they got enough debris down into the tank that the new pump/strainer may be clogged?

Aside from that, when doing a fuel pump it's generally recommended to do the filter at the same time. So for like $8 give that a try.

Outside of that, check grounds anywhere near tank/frame they may have fiddled with.

If you're only getting 50psi prior to the injectors, it's not an injector obviously.

Yep, just clean where it attaches to the body or frame well then paint over it. On beater cars i have even cut out the connector and hard wired things in instead of messing around. If you have to remove it in a few months just dike it and reconnect it with some shrink wrap/solder.
