I have a 1994 ranger 2.3 liter im having problems with it acting like it's getting no fuel going down the road I checked the relays and for vacuum leaks I filed it up last night and that's when it started to act like a redheaded step child can anyone please help me before I get a match thank you ever so much

 

Check the gas for water, water don't burn well in an internal combustion engine in large amounts. Also the fuel filter may be stopped up, or the pump getting weak, or the pressure regulator going bad.

 

The fuel pump and filter wad changed out at 142k the truck has 143k and some change on it now but ill check the fuel pressure regulator thanks ....if thats not it what next ?

 

Are there any fault codes? Get it scanned and post the codes (if any). It will help us narrow it down better.

In the mean time do what fordgirl suggested and check the fuel for water. Seeing as you have recently changed the filter and pump it could be the pressure regulator. Check the fuel pressure and tell us what you get.

 

my 94 4.0 had a mystery miss that could not be found, I went and R&Rd all the elctrics for the ignition, took it into a shop and got it back the same way as they could not locate the issue and said it might be carbon buildup. Put in seafoam and it ran terrible. Was considering a reman engine, but finally went with new injectors and they cured it. One looked very dirty when pulled. BTW engine has 310000 miles and the injectors were cleaned by ashop6-7 years and about 130000 miles ago! so it could be something like this, and no I had no codes showing.
