Just got my 1991 s13 240sx a week ago. You can see it here. https://www.youtube.com/watch?v=E4nq_Ih_4sk&t=
My issue is I installed a new fuel pump and it car ran and drove just only with the MAF out but is in limit mode. with the maf in the car just dies. This is a brand new MAF any help would be great.

More likely an ECU issue, or a bad MAF.

Test for voltage, signal, and ground from MAF first (brand new MAF is probably cheap Chinese crap, so don't be too reliant on its functionality).

Test fuel pressure at the rail also. Did you replace filter, or just new fuel pump?
