Replaced fuel pressure regulator and MAP sensor. Engine still won't run.

Thank you! I checked the fuel rail pressure valve, very little gas flow.

It ran when you put gas in throttle, and now it doesn't on it's own. Sounds like a bad fuel pump to me. No more restrictions?

Can I buy a rebuild kit for the fuel pump? I just put out $140 already, and $270+ seems a little steep for just a pump and I'd be paying for another fuel pressure regulator. I forgot to mention there was a black oily substance in the old pressure regulator, and it was clogged. TY :)

Not that I know of; That would not be an option for me working for the public. Not to be rude, but that's how you learn to work on vehicles, sorry, but you learn by your mistakes. We have all made them, and it can cost to learn. :-)
