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. :-)

Thank you for all your help! Enjoy the weekend! Pat

You as well and good luck.

another question on this...I checked out my throttle body...carbon and such all through it...cleaned it out and noticed...the idle air motor is stuck in one position...badly carbonized...cleaned off the air inlet plug...but it is still in the closed position is this normal..? I was told it should move freely as pressure is applied and then spring back to position...the spring doesn't appear damaged...what should the psi be in the fuel rail?

The Is a motor. No pushing. What engine size.
