2000 Nissan Maxima Hard Starting

Sounds like either weak battery or a weak starter not turning it over quick enough. Check thoses areas first and then go to the ignition switch and check

is there a check engine light or service engine soon light on dash?

if you jump a car then take it to get tested it will pass no matter what it off and get it tested maybe???

If you don't have problems on the road, it's ok. Try pressing the accelerator once before starting.

IF its not a fuel issue as in you checked your fuel pump, fuel filter, fuel injectors and pressure regulator, try having your timing belt looked at. Maybe its time to replace it. Check your crank and camshaft sensors as well.

Might be an oil issue. Oil when hot might be too thick for the pump to pump the oil easily in the engine. Check that and if not that come back.

It is stick shift and only starts by pushing it and dumping the clutch? Sounds like a bad starter or the connections didn't get tightened to it when the transmission was replaced.

mi nissan maxima has a hard time starting

My car was having the problem I had my ingnition switch change, stater and a new battery and now it's fine.

Yes, cam sensor can cause a hard starting condition, but not that common on a 2000 maxima. I haven't replaced single one on a 2000 Max and I have one also (maxima that is) . Never had any problem with cam or crank sensors. I think that your problem is somewhere else, like IAC valve circuit. Just a tip. Its kinda hard to diagnose something over the computer, without Consult2 (Nissan scanner) beeing hooked up to the car and seeing what the car is doing while cranking for my self.
