I had the code for "High Voltage to AIR" and the one for "Secondary AIR injection system fail"
I pulled out the old pump and it was shorted, so I slaved a new one in, turned the key to on (car completley cold) and the pump does not energize, I started the car and the pump does not energize. I took the pump and jumped 12v to it directly, pump energizes. I checked all the fuses and they wer good, both inside and under hood.
I do not have a meter, I suppose I need to buy one now.
I have heard talk of a "Realy" I have a manual but alas the emission system wiring diagrams are incomplete!!!!
The car had sat for a long time over 5 years not being driven hardly at all. I drove it for 3 hours, and it runs fine, but I am only getting about 19mpg- pretty low for a 5 speed v6.
I can clear the codes, but they come back. Perhaps I will install the pump and drive it a while to see if the PCM resets and detects it.
I did read a thread and the manual does say that the CCRM controls the voltage to the pump, but I cant find a diagram so I have no idea which wires to ohm check.
Thanks for your suggestions. Dongo
