The key will not turn over to kick over the starter. i got a new key assembly but cant figure out how to take the wheel apart to put it in

double posted backup one (i gave 3 choices there)
define cant. (cant figure)
or the anti-theft bolts confusing you , the FSM covers all that
why not read that first. then ask questions.

to make cars not easy to seal they make it like this,
90 to now.
it needs to be removed the whole assembly.
anti theft bolts,off, , assmbly off, may take steering wheel off too.
the hand to lock smith (just did a 91) and he
uses special smith drift pins to drive the hidden (backside away from thieves, internal lock pin, he tumbler comes out or he drills it out.
then a new pin, and holding new tumbler, and then test it , ok ,
the reversses all above.
the fsm covers this all step by step, why must you avoid books.
or read alldata.com

remove the starter motor. disassemble, clean thoroughly and assemble. the pinion should be jammed, so it cant come out to engage on flywheel

wiring to the starter; large cable coming from the battery to the
large post on the starter is direct current, hot at all times. there are two small wires that connect to the solenoid, one comes from the ignition.
Look for loose connection especially ground. If you jumper the connection on the solenoid to the large connection on the battery and it starts, I would suspect fault in the ignition circuit...

According to my wiring diagram, you should only have one small wire which is purple. That wire goes on the R or S terminal. The I terminal was used for cars with point system ignition before electronic ignition.
The purple wire should be hot when the key switch is in the start position.

put a new ignition switch in the car

I have a 93 pathfinder SE 4X4 automatic transmission that had full power, new starter and battery. Sometimes it will start and sometimes not. By passed starter relay by adding push button start and it started 6-8 times then nothing. I finally figured out that it was the neutral safety or inhibitor switch on the 4 wheel drive shifter. Just an idea..good luck

I am afraid that you will probably have to get a new ignition switch. You can take it all apart but you have to put it back together. Be careful taking it off. Remember how everything goes. Sorry. If you need anything else, I am here to help. Just contact me. Thank you for choosing FixYa.

maybe starter relay?

When you crank the engine are you getting a full 12 volts positive at the solenoid switch on the top of the starter?

Have you got a full 12 volts negative to the switch?

Also, check the earthing strap from chassis to engine is good.
