so i jst finished my sr20det redtop swap into my s13 and it will turn over but will not start.

I'm a little puzzled on this because my timing is correct, i have spark, and i have fuel. My fuel setup is a walbro 255 besides that and an aftermarket intake and exhaust its pretty stock.

I noticed when i pull the fuel pump fuse after trying to start it as the remaining fuel gets used up from the lines it starts to combust a small amount and u can hear a few puffs coming out of the exhaust. The same thing happens when u first put the fuse back in untill the lines r full of fuel again.
This makes me think that the motor is getting flooded.

So maybe my fuel pressure regulator is going and it is just letting fuel flow freely into the cylinders?

My ecu also stuck with a red light on. It then came out of that mode and started acting normal. i ran diagnostic codes and it ran code 55. Now it is back into the mode with the red light on and won't even go into diagnostic mode.

So idk if its my fpr, ECU or what it is i jst need to get my car running ASAP and any help will be greatly apreciated thanks.
