I have a EA to EJ and have problems starting. Pressurizes OK but floods when trying to start. A mechanic showed me that if he pinches the fuel intake line, it starts fines and runs thereafter. So I put a switch on the fuel pump pwr and turn off flow until start. We replaced the fuel pump relay and I check the fuel return and vacuum to fuel regulator. Also put the return line into a can and it fill up quickly at first 30 seconds of run?
Any ideas on the flooding. Could it be temperature miss-read at the ECU causing a cold start issue? At a complete loss. Should it fill up a large water bottle with return fuel in 40 seconds?
