98 v6 how much pressure should my pump put out at the shrader valve?

 

With no vacuum, roughly between 36 and 41 psi.

 

you mean unplug the vacum on the regulator? If so I have 40 but with vacum 30! Is that about right?

 

Yes, you are correct, by unplugging the vacuum going into the regulator. And those numbers are normal that you've measured.

 

The reason I am asking I have no codes and it falls on its face on take off but idles!
I have changed the coils pack,the cam sensor and syncronizer, the crank sensor, the tps, plugs and wires!
Any advice here?

 

I would try and clean your MAF next.

 

Where did you get the TPS? I went through 3 bad ones from autozone on my ranger before I got the one from Ford. I'd look at the MAF also.

 

It could be clogged cats giving you the flat feeling when you try and accelerate. Pull the secondary 02 sensors and see if the engine runs runs better when trying to put fuel to it. If so, then the cats are FUBAR.

 

Good point
