I've got an '04 Xterra with ~215,000 miles. Because of a recent breakdown I've replaced fuel pump(delphi), Distributor(Beck&Arney), starter, and new NGK plugs and wires. All this was replaced after being stranded where it would start and idle but die as soon as put in gear. After it all I assumed it was the coils in the distributor that failed.
Now the current issue- It starts fine when cold but after reaching a destination whether it's 10 blocks or 100 miles and trying to start again it will turn over but won't fire up without quite a bit of fuss. Lots of turning over and it seems that pumping pedal helps it start. Only codes I've had are bank1 sensor1 codes for O2 sensor.
Will a fouled O2 sensor trim back fuel once heated enough to keep it from starting?
Thanks in advance for your help. This is my first post but I've been lurking and using this great resource for awhile.
