when i turn the key, it cranks but won't turn over. the battery is good cause the horn works. what can it poss be? i'm so confused.......
help me please.....hehehhehe thanks guys.

 

crank position sensor, fuel pump, maybe a dirty throttle body. Do u have a check engine light?

 

It could still be the battery. I've had all my electric accessories work but my car wouldn't start with a weak battery. Jumped it, and it started up just fine.

 

maybe the fuel pump/ how do u know if it's the fuel pump

 

clogged feul filter..... try stepping on the gas a feww times (no more then 2) before cranking it....and try jumping it...make sure all lights are off as well as radio, heat/ac/defrost and doors closed

 

Crank Position (POS) has most likely failed, but pull the codes and see what you get.

If by chance you get 0505 indicating all is OK and you still get a crank but no start condition, replace crank position (POS) which is located on the bell housing under the car twards the front.

 

Horn sounds does not rule out the battery. Battery may still have enough power for the horn, hell the starter needs a lot more juice.

 

any special tools to change the pos? i think it's the crankshaft sensor. thanks tom

 

Might be a security system preventing the engine from starting. A similar problem was discussed on 5th gen forum. Check this TSB at http://maxima.theowensfamily.com/tsb/NTB99-063c.pdf

 

do you hear the starter try to turn?

 

the starter tries to turn and you can hear the crank but it does not turn over

 

one more hour b4 autozone opens/ how much does a crankshaft sensor cost?

 

its 60 from nissan

I see that u have a 99, check that the chip in your key is working correctly.

 

does it show any signal of barely turning over? my friends max just had same issue and his starter got worst and worst till it could barely turn over and stopped turning. Try banging on starter and seeing if it starts. If it does i think your starter is on its last leg....

 

Hey I have a 95 but, I had the same problem last yr and now this yr. I think that the starter should be in the same place on the 99, so it should be easy to take off, take it off and take it to auto zone and see if it has the sufficient power. I did that to mine, and guess what, my car is working.

 

Yhai, what are you doing... trying to turn your car on

 

freak! it was a low battery... good thing i have a optima red top so i just drain it and recharge it....now it's good as new

oh i let my baby sit for the last 2 months w/o stating her......shame on me.....thanks everyone for your help.
