I've got a '93 FD and we just finished dropping in a JDM motor from the clip I bought. We have fuel from the pump,(verified because we used the pump to drain the tank) but I dont seem to have fuel to the motor. A little ether and it will kick over so it has both air and spark. I still am not sure what the blue harness coming through my firewall thats not hooked up, but the pinout is different than USDM. The PowerFC shows all sensors reading and inj duty up to 12% while turning it over. Also, just to double check, which of the 3 hoses goes to which line on the motor? Any help would be greatly appreciated as I am in the shop all day today trying to figure this out...

 

as silly as it sounds swap the feed and return fuel lines. it may start as i found out the hard way fuel does not like to go revers

 

If I knew which one of the three went where it would help.... anybody got a high res pic of their fuel lines coming up the firewall and connecting? I think we tried every possible combination, to no avail. I think the problem is probably the blue harness on the engine harness (the only one other than the ECU plugs that comes through the firewall, but I dont know what it does....) Sadly a bit of a newB when it comes to actually working on a 3rd gen, little more comfortable working on my FC, but I want my FD for this weekend.

 

So I believe I'm dealing with the X-05 and X-14 harnesses... Explains the no fuel, but I was wondering if anyone has had any luck wiring the JDM harness with the USDM? Cant seem to find a wiring diagram of the JDM side, so I'm hoping someone here can give me a hand. I have both harnesses, so I can make a jumper that connects the two, I just need to know which go to where between the two. I run a PFC, and can bypass the fuel thermosensor, not sure how yet, but thats my next search...
