There is a black unlabeled button on the right of the steering wheel press in that button if it's not because your wheels are turned to far in one direction------------------
When you insert the key, turn the steering wheel to the left and right while gently trying to turn the key. If the wheel doesn't move that much, it means that the wheel lock is engaged. This happens on my Altima frequently, usually I just have to turn left and right and the key will unlock the wheel lock.
There is also a wear problem with the Transmission/Steering wheel interlock - sometimes the Transmission range selector handle does not fully engage at the upper most end of travel - there by not allowing the key to be disengaged - to check is very simple ---- Turn off vehicle, attempt to remove key, if key fails to turn- GENTLY push forward on the Transmission Selector Level to it's limit of travel & then try turning the key to the off position - it may take a time or two but my 1997 Altima does this occasionally & this is my work around..
that's hard to say it could be as easy as battery or something like your starter theres a couple things it hard to tell with out being there
Dead battery, faulty starter, or defective ignition switch.
try checking your fuses and fuse-able links
Best way to diagnose is to scan for codes, but not having that I would guess the ignition module then the crank/cam sensor.
check for clogged fuel filter, incorrect or improperly gapped spark plugs, or ignition timing
The tumblers in the key cylinder have most likely become stuck in the wrong position and you will have to replace the ignition key cylinder.
May be a defective ignition control module, or coilpack. I had a bad ignition switch that was cutting power to the fuel pump, when it does this listen for the fuel pump to come on before restarting. I have a 2000 Intrigue. I had the same problem and it was a crank case sensor. You might get a cheap fuel pressure gauge and hook it up. See what the fuel pressure reads when the engine dies (do this in the driveway). If the pressure is dying, try a new fuel filter. Answer Ignition switch
In general I suspect an electronic ignition component, I've seen this with a crank position sensor, ign. amplifier, and a circuit board that when it got hot it would warp flexing and creating an open in the printed circuit.
Probably the wrong voltage
it sounds like the neutral switch
Read the owners manual and u can't go wrong..
When i accelerate it goes slow i think my timing was set wrong a couple of times not just once
it's broke. if you car is not going into gear then it could be the trasnmision
its a nissan....
If your wipers keep blowing the fuses on your 1998 Nissan Altima, it could be a short or the wrong fuse being used. You may have a short in the wiring or the wiper switch, a bad ground wire, or loose wiring.
something wrong on the engine get it chek for any codes
Have you checked the fluid level? Have you changed the filter and fluid as normal maintenance?
The AT check signal light means that there is something is wrong with the transmission. A slipping transmission can be the cause of this.
No spark? are you sure? then probably bad crank sensor, or ignition module.
