Lift and slammed ranger

[Luis garnica]

Hey so my name is Luis and I have 2 ford rangers one is a 85 with a 2.8 with a 3” body lift, welded diff on 30’s and the other is a 84 than I’m in the process of slamming and I have some trouble with that one I’ll crank it over then it will sputter and die it currently ive already replaced the fuel pump but has the headers off so I don’t know if it’s a back pressure problem or vaccum lines also if I could get any info on how to go lower it would be greatly appreciated

There is no such thing as a back pressure problem.
Yes, check for vacuum leak/s
Check fuel filter/s
Check fuel pressure and volume.
