I have 2003 pathfinder 2 wheel drive 3.5L. 226,000 miles
Runs great when running and starts up fine when cold . When you drive it for little bit and get it up to temp and then let it sit for little bit and try to start, It will take like 5sec or more of cranking to start. It always starts as of now but realy needs to be fixed. Parts I have put on
New spark plugs
New coils
New crank sensor
Aftermarket fuel pump from oriellys
New fuel pressure regulator
New fuel filter
New radiator ( old one leaking)
New thermostat
New fan blads
Cleaned air maf
Cleaned throttle body

I have tried to prime the fuel pump few times before starting and no difference. Now I do have aftermarket fuel pump on here as the OEM was crazy higher priced. I have heard this would maybe cause a issue but when I prime fuel system and doesn't make difference when try to start it. make me wonder if that's it. Any help here would be great thx
Ok. Up date in late few weeks I have have had code P0306 come up on cylinder #6. Now it came up before I out new plugs and wires and came up angian after about a week Lter. Runs great when runs. My buddy the Nissan mechanic said probably the injector. Could this finally be a code to point me in the right direction. Hope so. Anybody know what the factory injector is for this car. Part # ? Thx.
update, I have installed new factory injectors new cam shaft sensors and new factory Nissan fuel pump. Still same problem. Any ideas...?
