okay so i went and installed my fuel rail with 50lbs(solder the wires to plus shrink wrap it) and put in a jgy fuel rail and nismop fpr.



now at the end of the rail on passenger side i have a fuel gauge)....

okay so i tried to crank it and turns out i had the fuel lines wrong...so i replaced them ( fuel filter line--- to-- fpr bottom, and vacuum lines to top...and return fuel line back to return line)


my car will crank but wont start......i have a gtir ecu and z32 maf.....


before i installed this i had a different intercooler setup,alogn with 370s.


i thought this would be a str8 swap to 50lbs and i wished the car just turns on but it just cranks....with a few stumbles of a turn over(to running)_

any ideas? before i start tomorrow morning?

i do know my fuel pump is working cause when i went to switch lines it had pressure in the line....and also my fuel pressure gague isnt reading NO movement at all.(if that info could help any)

bump

Do the 50 lb'rs require resistors? I know when i put 50lb injectors on my old set up they required resistors when i went from my old side feeds to a top feed set up.

no these dot i tested the ohms on them and they read the same as stcok 259 and 370s

fuel line goes from filter to rail ,fromr rail to regulator ,then from reg to return

he beat me to it. this is a common and overlooked scenerio. but easy fix, and would solve the problem

Fuel lines & Z32 wiring.... gets them EVERY time!

Easy way to remember - Regulator to Return.

okay so i switch the fuel lines from this setup orginally....i had it this way to start off and still nothing ...it would crank and no fuel pressure......then i did some research and i understood(or i thought i had my lines crossover) sooooooo i swithc it to the way it is now(the wrong way)...ill goo do that....thanks guys...


and the z32 MAF is legit cause that was my first thing to check......plus the wires are connected to the maf and the maf harness is soldered.

okay so i switch the lines around and plus(heres something i FORGOT to do...i think this made the difference...i put the fuel spacers from the stock back on (i forgot to) and boom...it started...thanks guys
