I hope im posting this in the right spot. I have a 93 sentra xe 1.6L. The other day I pulled it out of the garage and parked it. It was cold but its been out in the cold before with no problem. Later that night I put it back in the garage no problem. Next day it wont start. Turns over fine. I pulled the fuse for the fuel pump to de-pressurize the fuel system so I could take the hose off the fuel filter to check it. After pulling the fuse and turning it over to de-pressurize, it started! It died after a few seconds of course. I put the fuse back in thinking its working now and its back to just turning over but not starting. Pulled fuse back out and almost starts again. Anyway, I did verify fuel coming out of the filter so could this be a pressure regulator problem?
