I have a 1998 Subaru Legacy OBW. I did the EJ25 to EJ22 swap years ago.
Recently, the car started having problems starting when warm. It started when cold no problem, but if I turned it off and left it for a few minutes, then came back it wouldnt start until I waited a few more minutes. One day it just never started again... I took the fuel line off the filter and there was no fuel coming out at all, so I decided it was a fuel pump issue... I replaced the fuel pump and the car ran great for a couple weeks, getting the best gas mileage it had for awhile.... It has CEL through this all but I "smartly" did not take it to have them checked as I thought i had resolved the problem and they would go away soon.
After a couple weeks it started having the same problem of not starting when warm again. I cleaned the MAF for good measure and noticed that when the car was warm and would not start, I could remove the MAF sensor connection and the car would start with no problems... Then I shut it off, connect the MAF sensor and again it would start normally.... So I used this workaround for a couple days until I took it to have the codes read and their are several pointing to the MAF sensor, the Fuel Temp sensor and the CAM sensor. The guy at Advanced was kind of rude so I dont have the exact codes, but I can go to Autozone and get the exact codes if that helps.
But I was hoping if I have CEL for at least those three sensors that not all are bad? Could one cause the other to code? Where would I start?
