HI,

Well, for some reason my wiring diagram is not matching up with the connector pinouts for the different components we need to check, which means I could steer you wrong on the testing. I will opt out and see if another expert has the correct diagrams and connector pinouts

Thank you. Are there any codes in the computer? Are there any anti theft or security lights on or flashing on the dash with the key on?

Customer: replied 11 months ago.
no no
Expert:  AMEDEE replied 11 months ago.

Have you checked for power down at the starter?

Expert:  AMEDEE replied 11 months ago.

Here is a wiring diagram of the starting circuit on your vehicle. This is what you need to help pinpoint the root cause of a wiring issue (if the starter is not getting power with the key in the CRANK position)

Customer: replied 11 months ago.
Expert:  AMEDEE replied 11 months ago.

And what were the readings/results?

Customer: replied 11 months ago.
I have poweratstarter. I can jump itoffwithscrewdriver
Expert:  AMEDEE replied 11 months ago.

This would mean that there is no power getting to the starter.

Customer: replied 11 months ago.
I can apply power topurple wire andtruck will start.There is power from thebattery at starter
Expert:  AMEDEE replied 11 months ago.

again, this would mean that there is no power getting to the starter from the starter relay.

Customer: replied 11 months ago.
I told all ofthisto the screener
Customer: replied 11 months ago.
correct. Idohave constant 12v atstarter relay
Expert:  AMEDEE replied 11 months ago.

On how many terminals? One or two (with the key in the CRANK position)

Customer: replied 11 months ago.
With key incrank, justtheoneconstant
Expert:  AMEDEE replied 11 months ago.

Are you sure that the fuses are good?

Customer: replied 11 months ago.
Have checked them probably 2 dozen times today.Also No turn signals
Expert:  AMEDEE replied 11 months ago.

And has the PNP switch been replaced?

Customer: replied 11 months ago.
Not today butr yes.The shift indicator is working.I even tried tostartinneutral
Expert:  AMEDEE replied 11 months ago.

Then you should be getting TWO powers going into the starter relay (on the female terminals) with the key in the CRANK position. Look at the wiring diagram I sent

Customer: replied 11 months ago.
My keyboard is messing upalso asyou can
Expert:  AMEDEE replied 11 months ago.

Then the ECM grounds the third wire which closes the contacts inside the relay which allows power down to the starter. OF course you will need to check for this as well
