Car cranks fine but now won't start at all. Replaced fuel filter, air filter, pvc valve and plugs. There are no engine codes showing and I got a nice flame when it backfired today after using starting fluid in the air intake so I assume there is spark. I got it running last weekend and it runs like a top when it does start. Just hard (impossible) to start so I;m leaning towards fuel system, relays, pumps etc. It is extremely cold here in Ohio (13F at nite, 28F daytime high temp) and that seems to magnify the problem. I know there was a technical service bulletin issued Jan 2003 from Nissan concening cold weather starting tips so this must be a problem. Any suggestions?
