Hey guys, i have searched everywhere doing google searches, going through hours upon hours of research on all 240 forums and nissan forums with no luck just yet. heres what happened.

a month ago i crashed my 90 coupe, it had a running s14 sr20 in it. i drove it home it drove fine besides the crushed in door and broken glass all over the place, anyway. i got it home and parked it. few hours later went out and moved it into the garage backwards to get it ready for a partout.

long story short i got a 93 hatch se. i was told the whole harness was one harness from a very unreliable source (i realize this now :picardfp:), so i numbered all wires on the ecu plug and cut them, then i was told that the harness unplugs (thanks for nothing). so i reversed the process, soldered all wires back together and shrink wrapped them. well i had to do something different when it came to the grounding for the ecu and all ecu grounds because they were all running to my main ecu ground, we pulled the motor from the coupe, wiped it down and put it in the hatch.

relocating the battery again my friend accidentally mated the battery terminals together with an extension while the cables were connected. no big deal, so i thought.

wired in the fuel pump switch becuase it didnt work, so atleast it primes now (coupe had the same problem).
go to start it..... nothing.
replugged in the maf.... nothing.
unplugged and replugged in the ignitor..... nothing again
:wtf:

replaced all fuses still nothing. we never took the cas off or anything it came out running, and went in not basically.

im so fed up i was going to just buy the wiring specialties conversion harness but i figured maybe someone knows and has the magic touch before i hang myself with my sweet ass auto seatbelts.

suggestions?

Need more info. Fuel pump primes, but does it crank? Is it getting spark? Is it getting fuel? Check all the wiring, check timing, and also check for vacuum leaks.

Edit: Is it like this one? This is what was happening to my car, turned out to be wiring.

thats what im trying to find out, as of right now i have to do some stuff on the dash plug to make it work, someone had brought up the idea that since i dont have the dash plug plugged in it could be the problem, also if you can post some pictures of the grounding setup you have going on from your pin 50, ecu ground. as of now i need to know if the white wires that i have running to the ecu ground should be going there

My car is in the shop getting new wiring and ECU harness is a mess. Will post after pics with all the grounds, etc. Check your engine bay harness, my problem was there.
