Ok got it running and fuel pump working now still losing power but now also runs good for a bit but then acts like it has no go. I press gas and it goes very slow. Help please

 

Bad IAC

Bad fuel pump.

Those are my guesses of course..

 

They are brand new on my truck. How can I check them

 

Lots of junk is coming from Asia. You can test your fuel pump with a gauge. You also may have a bad fuel regulator.

 

What and were and how is the fuel regulator

 

Since you have a pre-OBD II Chevy, with the TBI fuel injection, the fuel pressure regulator is located under top of the TBI unit. You'll have to remove the two fuel injectors off to replace it, as it attaches to them. You should be able to see the fuel line attaching to it. Probably need to attain some new gaskets when you do so. It's really very simple to do. Easier then working on lots of carburetors, as I have done.

 

Is the fuel filter restricted? To check fuel psi there is an adapter that goes in place of the fuel filter and allows you to attach a psi gauge. As I remember fuel psi is 9-13 psi. Hope this is helpful.

 

Checked it and is fine I will look at my tbi. Maybe rebuild again. It is killing my alternator. Can't figure out why. I have had 3 in a yr.?? Help

 

I was told my fuel pump was fine but I did not think so so I took my bed off again and took out pump and yep the wire was bad inside the tank got a new pump and am putting in today I hope this fixes it. I love my truck but after 2000. To fix everything. It better. Thank u.
