Cranking but no start

Okay im in the middle of troubleshooting and I cant seem to find the problem. Heres what happened, brought the car down for 2 months to try NS conversion so when I get BNRs I know which route to get. Also did a lot of upgrades at the same time. Sorry for the long read its painless I promise.

I try to start the car after all said and done and I just get a lot of cranking, I thought I had flooded it so I removed leading plugs and cranked with no fuel or egi relays. Saw that no fuel was coming out during deflooding, so I tried cranking with the fuel pump relay in and still no fuel. Lastly I checked for spark and thats okay.

My injectors were just cleaned by RCeng 2 months ago and they did tell me that long projects with injectors sitting on shelf may stick but I cant imagine both primaries sticking. I know the fuel pump is working because I can hear it when I primed the system and actually sprung a fuel leak while priming which is fixed now.

The car is on a Power FC and all my sensors seem to be functioning, I even logged the sensor values while cranking if anyone is interested at taking a look at that.

During this 2 month downtime I rewired fuel pump and battery relocated to bin. During this troubleshooting I put pump wiring back to stock with the exception of the extra ground that splices into existing fuel pump connector ground. Also moved battery back to engine bay in case I was getting a weird voltage drop. Followed this write up and removed emissions. Rotary Resurrection home of the budget rebuild.

What else can I test?

Embarrassing lol. Me being a idiot and not double checking my work. Fuel feed was swapped with return line. Didn't realize it until I contacted my rotary buddy and we went through everything over the phone and I realized it.

Unfortunately I have a really bad idle. Got to fix that now.

At least you got it sorted out. Seems like a common mistake.
