Stuck in park. To start has to be forced into

It's a bad or failing neutral safety switch that's not detecting that your cars in park. No check engine light? That should come up on the ecu

If the starter motor won't crank, then check voltage and ground circuits at the starter motor, when problem is ongoing. Any testing at the starter motor, make sure tranny is in park or neutral and the parking brake is set.
Unless you can do some testing, I'm not sure how to help?

Bad brake sensor on shifter or the fuse was blown did you force it out of park

Hello rhw... It could be simply that the car isn't fully in park. Go out to the vehicle with the key. Turn it to on and put it in neutral. Then use some force to jam it into park. Then try to start it. Repeat if necessary. Joe

Thanks for choosing Fixya!

the neutral safety switch may be bad or out of adjustment. if switch is bad, no voltage will go through it in park to start car. you can also check to make sure it is going all the way into park.

sounds like you have a bad neutral safety switch. it's usually attached to your brake pedal. i'm not sure on a newer maxima but check underneath. here's what it looks like http://www.autozone.com/autozone/catalog/parts/partsProduct.jsp?itemIdentifier=124168_0_0_&skuDescription=Duralast+/+Neutral+Safety+Switch&brandName=Duralast&displayName=Neutral+Safety+Switch&categoryNValue=15799999&sortType=&store=966&isSearchByPartNumber=false&fromWhere=&fromString=search&counter=0&itemId=218-0&navValue=15700218&filterByKeyWord=neutral+safety+switch&productId=124168&searchText=neutral+safety+switch&categoryDisplayName=Electrical+%26+Lighting&parentId=57-0

sounds like park safety switch,there are 2 switches 1 neutral and 1 park, if it starts in neutral,it is working,if in park,and does not start usually means bad switch or wire off.

1.Shifter linkage could be out of adjustment, and not allowing the Neutral safety switch to be bypassed, when in the Park position.

The shift linkage, could move the arm of the neutral safety switch far enough, to bypass it when the shifter is in Neutral, but not far enough when the shifter is in Park.

2.Perhaps the Neutral safety switch is bad, or has come loose on it's mount, and is out of position.

check your fuses if they're all good then its your park safety neutral switch that's bad.

You culd be having more than one problem. First if you are having problem putting the car in park. The car may not actually be fully in park and therefore the neutral safety switch is active and telling to car you are in revers or in gear. If this is true then your car won't start for safety reasons. Try putting it in Neutral and see if it starts then. Ormay have a neutal safety switch that is bad. Can you hear the starter click when you turn the key to start?
