Hello and welcome to JustAnswer!

You could have a handful of things going on and it will most likely take some electrical testing to determine exactly what is happening. It could be a blown fuse, a bad relay, wiring, an internal issue in the integrated power module, or it could be the ignition switch itself.

When you turn the key to accessory nothing powers on at all, just as if the key was off?

Your post last night said that the IOD fuse is open. Do you mean that the fuse blew?

Customer: replied 5 months ago.
Fuse was on wrong position and I turned it around

It's going to take some electrical testing to determine what is going on. Is that something you're intending to try to do yourself?

Customer: replied 5 months ago.
where should I start
Expert:  sprinkles08 replied 5 months ago.

The first thing you need to do is use an incandescent test light to contact the two terminals on top of fuse 25 with the key in the accessory position and see how many terminals light it.

Customer: replied 5 months ago.
what kind of tools I need
Customer: replied 5 months ago.
let you know tomorrow
Expert:  sprinkles08 replied 5 months ago.

You'll need an incandescent test light.

Customer: replied 5 months ago.
non of those terminals light it
Expert:  sprinkles08 replied 5 months ago.

Does the instrument cluster stay on with the key off?

Customer: replied 5 months ago.
no
Expert:  sprinkles08 replied 5 months ago.

Can you try swapping the accessory relay with another and see if it changes anything?

Customer: replied 5 months ago.
no change
Expert:  sprinkles08 replied 5 months ago.

How many power feeds does the relay have with the key in accessory?

Customer: replied 5 months ago.
two
Expert:  sprinkles08 replied 5 months ago.

If you apply power to pin 87 will the radio come on?

Customer: replied 5 months ago.
no it doesn't
Expert:  sprinkles08 replied 5 months ago.

Is there power at the fuse when applying power to the relay terminal?

Customer: replied 5 months ago.
Expert:  sprinkles08 replied 5 months ago.

I'm a full time tech and at work this morning, I'll get back to you as quickly as I can.

Expert:  sprinkles08 replied 5 months ago.

You'll next need to pull the integrated power module up and locate the pink/orange wire in pin 4 of connector 8, the white 15 way connector with rotating latch. With power applied to relay pin 87 is there power there?

Customer: replied 5 months ago.
there is no power and I also find out there is to much bouncing in the ignition switch between ACC and ON could it be my ignition switch
Expert:  sprinkles08 replied 5 months ago.

If there is no power there then you have an open circuit in the integrated power module and it will need to be replaced.

Customer: replied 5 months ago.
can you tell me some about ignition switch I need to know what part of it I need to change or what is most common problem with it . is it ignition cylinder . I like to do that before changing the IPM
Expert:  sprinkles08 replied 5 months ago.

There is no question that the IPM needs to be replaced.

You'll have to remove the lock cylinder housing and remove the lock cylinder from it to see if you need a lock cylinder, housing or both.

Customer: replied 5 months ago.
Do I need programming for ion
Customer: replied 5 months ago.
IPM
Expert:  sprinkles08 replied 5 months ago.

No, it will learn configuration when it's plugged in and the key is turned on.

Customer: replied 5 months ago.
I replaced the IPM everything is same but I find out when I move gear shaft to reverse we get some light in NAV panel also when we start the car before applying for break you should rich for gear shaft other than that gear shaft doesn't move
Expert:  sprinkles08 replied 5 months ago.

Where did it come from?

Customer: replied 5 months ago.
salvage yard
Expert:  sprinkles08 replied 5 months ago.

So you didn't see it working on another vehicle then, correct? Either the replacement is bad or your test results were not valid.
