Try to short the starter...see if you have power there.

Good News while cleaning relays I got power to the starter and and it turns the engine over, getting fuel so now I have to see why can't get it to engage with key.. What would be a good reference book that details what is what under the hood as far as the electrical fuses and relays. Thanks for all the help!! Looking a little better at this point..

Glad to see that you're making progress.

The link to the wiring diagram document, that I included in the first post or two, has all the information you need relative to the electrical systems, fuses and relays.

Is it possible that the key you have is not programmed to the car's processor? It's RFID in the key must be matched to the car.

All,

Ive got power to all the rlays and fuse boxes. These are the errors as they appear on the dash
1.Fails Safe Engine Mode
2.Incorrect part fitted
3.Engine coolant low
4.Open trunk (it was)
5.Tranmission Fault
6.Bulb fail rear
7.Door Open (it was)

Like I said power everywhere, when I cross the starter engine turns over but key will not start car, when key is turn to on I hear clicking in the throttle body. How do I know if the key is not programmed, I would think since it activates the throttle body that its gtg?

Many if not all codes could be caused by a low battery so for now put them to the side. Have you tried to move the shifter from “P” to “N” and try starting?

Yeah, try shifting from "P" to "N" just to see if the shifter is unlocked. Also, on my car, with the steering wheel adjuster knob on "auto", when I put the key in the ignition the car will recognize it and move the steering wheel to stored position '1'. If it doesn't recognize it the wheel will not move. Not sure if you've got that far yet.

I would first identify that you have power to the relay for the starter, then replace the relay and you can do this by swapping it with a like relay that is in the car. You could have a bad connection in the fuse/relay block in the engine compartment that houses the starter relay. If that is not the cure look at the ignition switch and control module.

Gus tested relay and it has power, shifted into N and same conditions, no change and did not start. Also I am buying a new battery to continue with the testing Ive been using a booster on an old battery.

If you have the OBD codes let us know what they are. Not what they mean but what they are.

Gus,

Tried to get tool from parts store to run diagnostics and it didn’t work “their tool was junk”.. Can I buy a descent one reasonably?

Thanks
