Re: My 2002 Nissan Maxima hesitates to start
If vehicle hesitates to start do you mean long cranking time (posible fuel pump) or no crank at all then suddenly starts then it is possible starter solenoid (notorious) - complete starter assembly needs replacement.

It shoudn't be. Your oxygen sensors detect the oxygen in the engine. A misfire can be a few things, such as spark plugs/coils, wires, distributor cap and rotor, cam sensor, crank sensor, ecm. I would start with a tune up. If it has been more then 75,000 miles since you changed the plugs and wires, it could be that. Has it been acting up, such as hesitations, stalling when you slow down or stop?
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.
is the check engine light on?? i would suspect your crank angle sensor. replace the cam sensors too. nissan had problem(there is a campaign) with those, so they came out with a crank and cam sensor kits. get the kit ( at a dealer ) and install it. actually have your nissan dealer run your VIN number to see if you don't have open campaign for it, if so, they will replace them for FREE. But that's what I would be looking at if one of those came to me to fix.
