The Black / Green wire on the 3 wire inertia switch connector ?

 

The 3rd wire on the inertia switch is a trigger to the SLCM that probably makes sure the doors unlock during a accident or a time delay after the point in time of the accident

The socket CA19 - 10 on the SLCM is not described on the wiring " break out " sheet preceding the specific wiring diagram page

Once the inertia switch is triggered and flips over to the 3rd contact , the SLCM sees this as a ground seeking wire path

 

So where do I go from here??,,, Pull all fuses again??

 

where did you find a replacement not in park switch ?

Your first one ( original ) may have been fine

 

The lever was broken on it, The car was starting with the old fan relay module in just that the fan wasn't turning on startup, after replacing fan module it won't turn over.

 

You may have had more than one intermittent issue at the same time in squaring up the car

By jumper Ing the inertia switch you took it out of the equation

There is a non crashed X300 that came in last month FOR A INERTIA switch

Need a between the front seats center console lid with your interior color code on your door data plate ?

This Wednesday after a morning Dr. appointment I plan on going by the salvage yard and drilling out some original not in park switches as there are 4 X300s there

I can use a spare down the road

 

Well, Reconnected inertia switch now fan starts in run pos but still no crank, Rechecking all fuses again

 

By tickling the BPM you may have put it out of it's logic steps and hung up

It can be reset with a " hard reset "

The reset is bringing both battery cables together for some time , the longer the better

 

Damnedest thing, Pulled all fuses & relays from left ,right eng bay and left heel board and nothing, Started taking center console apart & decided to check park light and it was working so turned key again and it started with no lights, put console back together and it still starts.

 

The ground wire on pin 5 of the ignition switch connector has a ground stud point somewhere that may have been disturbed under the dash

This single wire is needed for starter command and the king relays to close to power many many things in the corners of the fuse boxes with the exception of the left engine bay fuse box relay ( horn )

If the ground wire is on the edge of badness it will cause intermittent problems throughout the car including instrument cluster warning lights as the systems, they flag are not fully and partially powered

I found corrosion on my pin 5 of the ignition switch connector

 

A detail of the 5 fuse boxes is that there is a connector on each box attached to the bottem shell of the fuse box

You won't see this until you remove the fuse box from the car

The one for the right engine bay fuse box would be the fisrt one to check followed by the left engine bay fuse box

The improved environment of the other 3 fuse boxes is much better

 

Ok, well took it around the block, got check eng light code reader said random misfire I cleared the code now won't start in park but starts in neutral went around the block twice code did not reappear but I have the anti skid light on, guy I bought it from says it was on when he bought it

 

I have yet to obtain a not in park switch from the salvage yard as yours seems to be backwards

Cold

The anti - skid light will not clear after fault removal until you reach 12.5 MPH 3 times

The first thing to do with a persistant anti skid light is to clean the sensors faces along with the wire connectors on the wheel hubs

They are plastic bodied and break and exspencive to find replacements so don't try to hard to remove , there is a trick

 

It started multiple times in Park,Then I drove it, Man this car is confusing ,,, I found out the anti skid light has been on since the guy I got it from bought it

 

Banging my head against the wall,, Just like yesterday I get the center console apart to this point and now the car starts in park again.

 

I haven't touched the switch

 

It's acting like you have a punched wire on the not in park switch

The pinch can be " making " the switch wire

Where did you obtain the current switch from ? it may have the wrong depression dimension confusing your troubleshooting logic with a added variable of consideration

 

I got it from a electrical supply place in Sacramento, I just drove it around the block with the console off and now it won't start in Park again

 

Private Mail me with your mailing address as I plan on getting you a early Christmas gift from the salvage yard

 

If you place your hand on the ignition switch key barrel area as you move the shift lever out of the park gate detent you should feel the key barrel lock solenoid, click saying the not in park switch is changing state or making
