redtop SR20DET swap, crank but no start

[chris_guthrie]

So a little background, I picked up a s13 coupe and ordered a s13 (180sx) front clip. Since I had the whole clip, I did a RHD swap, then swapped the sr in. Finally got everything buttoned up and now she won't start. 

I used everything off of the front clip, everything that has a plug is plugged in, every component is where it should be, literally everything was just swapped over from clip to car. 

For the wiring, I used the underdash, upper and lower engine harness from the clip (since it was cut near the seat) and the chassis harness from the USDM coupe. Just wired up the important things (fuel pump, brake/tail/signal/reverse lights, cig lighter, ashtray light, ebrake signal)... which should be irrelevant to the problem I'm having. 

When I went for the first start, I noticed fuel pump was not priming. Traced that issue back to the egi fuel pump relay (relay was fine but seems to have no ground signal from the ecu). Used a jumper wire and the fuel pump works fine. I also noticed though, the egi relay (eccs relay) is also getting no signal. With the fuel pump jumped, still no start. Since the eccs relay was getting no action, I took a look at the ecu and the red light was on. 

Did about a week of research, found the most common cause was a internally shorted ecu. Ordered one which came in today, hooked it up, same exact issue. Ecu was boxed very well, so it is very unlikely that it was damaged during shipping, and even if it was, the odds of it having the exact same issue are highly unlikely. 

This leads me to believe that it is a wiring issue. Of course I could be wrong, but based on what I've seen so far, everyone who has had the same issue has had a bad ecu. So at this point, I am looking for advice on where to go from here. 

Everything is hooked up exactly how it was on the clip, which was checked and in good operating order when I bought it. I didn't have to do the wiring mods that are required for a motorset since I had everything including the factory boost controller and fuel pump resistor that came with the clip so now I want to make sure that I'm not perhaps overlooking something simple or whatever the case may be. 

Sn: all work was done by myself, in my yard, with no garage and using just regular hand tools for the most part. I do have a multimeter and am no stranger to wiring, however I am not the best at diagnosing ecus. Always went by the general rule of no fuel, no spark, replace ecu. Also, I haven't checked the plugs for fire since right now my main concern is getting a ground signal to those two relays. Any real help is really appreciated, and any bashing about the rhd swap is not needed as I just threw that in there in case it may be relevant to the issue. Also posted this on zilvia.net a few minutes ago.

Did you use the engine bay chassis harness of the clip or the USDM one?

I used the one from the clip.

Bump. Girlfriend left for AIT today, so I'm looking to really put my head down and get this puppy running.

Also, anyone in the central va area with a running sr that could swing by and wouldn't mind letting me try their ecu to see if that's the problem, or vice versa, I would really appreciate it. I'm at the point now where I'm almost certain it's a bad ecu, but I need one that I know is good to try before ordering another new one. Already have 2 that may be bad, and would just like to verify before I spend the extra cash on something if I don't need it. Crashed my daily on xmas eve and looking for another daily now so every penny counts... and if I can get this running soon, that'd help out tremendously
