2.9L fuel problems

Hey guys im new to this website my older brother used to use it all the time when he was building his rangers so im kinda familiar with it but not so much anyway about 2 months ago i traded my car for a 1988 ford ranger stx 5speed it has a 6inch skyjacker lift with 33x12.50r15 pro comp mudd terrians so when i got the truck i noticed it was not a powerhouse because it had a 2.9 and 33s so i didn't think anything of it until one day i got in it and i went to pull out and it just died so i figured ahh i just stalled it so started it back up and i had to ride the clutch alittle bit just for it to pull out now when it started acting up a lot it cuts out going up hills in 3rd gear almost like it shuts off completely and comes right back on so i called up my brother an told him the whole story hes like it could be a weak fuel pump so i popped the hood and pushed down on the valve stem looking thing on the driver side of the motor and gas is just like flowing out like it has low fuel pressure now i wanted to get someones advice before i go out and replace both fuel pumps because my luck it will be a cheap fix but if any of you guys have any thoughts on what may be wrong i would greatly appreciate the help! thanks,justin

Sure.
Fuel pump relays, clogged fuel filter, pinched line, bad fuel regulator. And, of course, bad fuel pump...
Have to eliminate possibilities one by one.
Borrow a guage and thread it on to the port and verify fuel pressure, before and also after the fix.
Good luck

i had the same problem for a little bit but it was just a fuel filter. i had a spare but i put some fuel system cleaner in and it worked fine. if the vehicle is running it should be doing alot more than just flowing. because of how much of a pain it is to get to the fuel filter i would just try some type of fuel system cleaner. the only kind i found to work was lucas. theres several kinds if you get any get the kind in the white can. but also check for pinched lines

Fuel filter is the most likely suspect.

If you check everything and still fail to find the cause, your just like me and the issue lies in the tank fuel pump sock. Make sure your tank is clean and the sock is not getting clogged up. This took me a few weeks to find.
