01 sentra, i just got from a used dealer. had it parked n my drive and it wouldnt start. so i put a new battery in it, and it still wont start. i have had it towed to the shop and tehy get it to start everytime. i finally put two and two together and realized that everytime i cant get it to start it is when the car is on an incline. not even a drastrict incline. anybod have any idea what this could be?
electricity starts an engine.... so... maybe your battery is low on water?? possibly a loose ignition circuit wire that doesn't touch right when it's on that incline, but that means it wouldn't be true if the car was leaned the opposite way.
*shrugs* i've heard of this before but never really understood it.
if it's an AUTOMACTIC... maybe the tranny needs more fluid for it to start... maybe the nuetral position switch, but that's electric as far as i know... dunno... i only drive manuals.
can't really think of anything sides the batt that would keep a car from starting on a hill.
even if the oil was all to one side of the engine.. it would still start.
ahhh.... wait a sec...
the fuel pump.... if it's not picking up the right amount of fuel cuz it's on the incline... how much gas you got in the tank??
and if it's full, maybe the fuel pump pickup is damaged... or not riding correctly...

gd... if i could only make it past the lower class, i'd be rich. damn facists.
got 3/4 tank. i have had the alternator and starter checked, but the shops say they are good. how can i narrow it down to the fuel pump. would this only cause the car to be almost impossible to start on a hill, because on flat ground it start great and runs fine?
there's a chance... but with 3/4 tank i'm not sure.... it depends on where the fuel pump picks up the fuel from... have you tried starting it with the car positioned oppositly???
like if it won't start with the front of the car pointing up... try turning it around so that it's pointing down...
but basically if for some reason the fuel pump is sucking in air cuz the fuel isn't reaching it.... but again you said you have 3/4 tank.
another possibility is that you don't have enough coolant in the system and the water pump is overheating... the coolant sensor is overheating.... the thermastat isn't submersed... because you only have enough coolant for the coolant to hit those points when it's on level ground....
again maybe switching the car around my change that...
but with the car starting fine on a level surface it fully sounds like it's some sort of fluid related prob... the battery fluid is too low, the fuel pump, or the coolant.... *again the oil...even if the system was oil starved wi/ none in there, it'd still start, albeit it would overheat and spin a bearing... way bad*
other than that... a loose wire that's dangling that hits right when it's not on level ground...
but that should change if you point the nose of the car the other angle.
btw... this is all guessing.... but i just can't think of any other reason it would do that. but i'm not a pro, just a shadetree mechanic.

did think of one more thing... i've heard that certain Honda's have an actual engine leveler... like on a carpenter's level.. *the bubble in the glass tube* and it has something to do with calculating g's while driving the car...
i've no clue if the sentra even has one of those, but ey..

Heath..
just asking..
there some way that effects whether the car starts on an incline?
i don't know anything about it sides it's an RF device... i think... though i'm thinking of keyless entry, but i'm guessing it might be RF too.
i have never heard of a car not starting because its at an incline. call a nisssan dealer and ask for parts give them your full vin# and they should be able to tell you if your key is chipped. or if u want to give it to me and i can check for u. ill ask my techs and see what they think if they have evr heard of this. what did the shop tell you they did?
