Default Having fuel problems after swap

I swapped a 2.2L from a 97 impreza into a 95 impreza. Used the 95 1.8L intake manifold and wiring harness, stock 95 1.8L ECU. At the same time I swapped it from FWD to AWD, which included the rear x member, diff, axles, transmission, gas tank. Now I know the AWD tank has an opening in the middle for the driveshaft to fit through. My problem is that I don't appear to be getting enough fuel pressure to keep the car running. It will take about a minute of cranking to get the car to start, then it barely runs, and when I try to drive it, it has no power. It is also throwing a code 62 (fuel temperature sensor I believe) My question: is the 97 pump compatible with the 95 ecu? Also, is there an auxiliary pump to pump the fuel from the driver side to the passenger side of the tank where the main fuel pump is? Any input is appreciated, thanks.

Im going to offer some simple advice this might work might not. I hooked up my fuel lines all wrong, Even though Fuel Still got to the injectors and would occasionally fire the lines were all wrong, Look at your old manifold Fuel lines and follow them to where they lead, compare them.

Also if your using the 1.8l pump it probally flows alot less than it would for the 2.2 as the injector sizes differ, Get a 2.2 pump and try that too.

I had done the same thing years ago.....crossed the feed and return lines. I could get the car to start, but it would not run. Switched the lines and all was well.

Start with the simple stuff. The 93 pump should be able to feed the injectors fine. Another area to look at would be the lines at the tank. Make sure you have the feed, return and vent lines straight. It would suck to be pumping your charcoal canister full of raw fuel.....
