Its been awhile since I've gotten on here to seek out some help. I've been working on (slowly) doing a swap into my RX and ran into a major issue that might abandon all hope on the car.

Car with specs:
1987 Subaru RX coupe
1993 Legacy SS EJ22T engine
1998 Impreza 5mt 3.9 tranny
1991 Legacy SS 3.9VLSD

I have everything installed into the car currently (still got a few small things to finish but enough to start and drive it) but I'm getting a crank, no start. Fuel pump isn't getting grounded but with 12volts on the main power for the fuel pump, it kicks on. I have a good harness as far as I know (been spliced between the EA82 harness and the EJ22T harness) and have had it checked out by another Subaru enthusiast that has done quite a few of these swaps. His board name is suberdave.

With that being said, no fuel, no spark, just cranking. I don't have the instrument cluster installed yet so no Check Engine light is wired up, no tach and no gauges period right now. Theoretically though, it should fire without these items hooked up but it doesn't. Someone told me that it could be a crank sensor buuuuuut the fuel pump would still come on like it should without injector pulse. I'm leaning toward an ECU issue but I could be mistaken and trying to find an ECU has been kind of hard locally for some reason.

Engine has 200k on it and was pulled from a running vehicle. I however did not pull it but I have two sources that said it was a runner before stripping. I got the engine out of the car, some misc parts were missing from the MAF, to the intake piping, PS pump and a few other odd-n-ends. Harness was partially stripped so I finished stripping it and merged it with the EA82 harness. I'm using the EA82 fuseable link block, fuse block and accessory harness, along with the cranking system but the engine harness is all EJ22T.


So where should I begin to figure out where my issue is?

well, there's no doubt about starting without the dashboard stuff... i.e. cluster and whatnot.

I would just plug the instrument cluster in to see what the codes are if you are able too.

I have started this car before without a cluster in it when I first built it. It was a FWD auto car with a NA engine. The original engine was toast so I did an AWD 5-speed conversion on it and dropped the engine in when I was still wiring up the cluster and it ran fine.

But I think you're right. I need to get the dash back in and the cluster plugged in with the ECS light wired in to see if I'm getting codes.

yeah that would be your best start point for your starting issue, then you can see if you need to fix a sensor that is causing you to fail on startup

You can just hook up a bulb to the CEL pin on the ECU. run 12v to the bulb, and then the other lead to the pin at the ECU.

How positive are you that the wiring is 100% correct? Does the fuel pump turn on at all when the key goes to the ON position? It should turn on for about 3 secs. to prime the fuel system. If you don't hear it turn on initially, I would suggest you look at your power supply routing, relays, and ignition circuit.

The whole harness was checked out by a friend of mine that strips and swaps EJs into EAs all the time. Has done multiple swaps too. We checked all the powers and grounds to make sure everything was good to roll.

The fuel pump doesn't come on at all. I can use my Power Probe and get it to kick on but I still don't have spark. I've also checked out the relays for the ignition and fuel pump which are good.

I need to finish cleaning out my garage so I can get the car in it out of the rain to work on it.
