well after replacing everything with my harness and all the car runs at idle as long as no maf is plugged in. if plug in maf it dies. and again this is the maf from my dd 240sx. but it will run with no maf but if accelerate it it back fires like its running rich and hesitation. so...... went to the fuel next

k well as the return line had no fuel coming out. (disconnected it up front beside the fuel filter) i took out my fpr and fuel came running out at the end of the rail. so figured i found the problem. replaced the fpr and put all back together and started the car. same thing no fuel coming out of the return line. car dies if maf is plugged in but idles with no maf but STILL no fuel out my return line!!! soooo is there a huge clog or something in my lines you think???? after the fpr???

heres a vid of how it runs. and i cant plug maf in or it dies. and it is a good maf as it is from my dd 240sx
