fuel

So got a 90 B2 with the 2.9 and need to do a feul preasure test feels like its starving so my question is I want to check at the fuel filter to make sure its pumping like its suppose to so it says fuel pump should be at 100-110 PSI does that sound right and then I want to go to the schrowder valve and check to make sure its giving proper PSI from the fuel preasure regulator and is that suppose to be between 30-41 PSI sorry just confused have never done these tests. And thanks in advace

should be 35-45psi.

the important part is what is the pressure when the engine is sputtering?

Ok and what's the best way to do that hook it up and drive it it seems to only do it when ur driving and punch it a little but if u hold it all the way down it will do it till u back off of it

Ok update my PSI with key cycled twice is at 38-40 and with car running its at 32 PSI anyone think this could be the computer runs fine at idle but when u get going down the road it starts stumbling and bucking when u gas it no matter what temp its at help help help please

thats a arcing plug, wire or coil/cap. fire it up, get your hose and splash the wires all the way down to the plug, and the cap/coil. wait for the blue spark. if you dont find one let us know.

Ok so probally best to do when dark out I'm guessing so possibly could be from a wire touching another plug wire also thinking about after that test if I don't see any arc switching out coil because aren't they kinda funny when they crap out

On the 2.9 does anyone know were the wire on the ac wiring harness goes there is two plugs and one ground wire I got the ground and the ac one figured out but don't have a home for the other plug
