my Fuel pump cycled everything came on but a scan tool showed faulty clutch position sensor so I would check your wire from pcm
That's because the clutch pedal low reference signal is spliced with the fuel tank pressure sensor. If you're not paying attention, you can easily cut that entire wire out when thinning out the evap system. This almost got me too.When I thinned my harness somehow I cut the clutch position sensor at the pcm plug. Apparently others have came close to doing the same so idk if the videos have a misleading step when doing a Turbo kit..
It reads 9.6v to both frame ground and pin 85.You said is has 9.6v (which is a very odd voltage). Did you measure that using frame ground or 85 on the relay? Can you tell if that relay even clicks?
From everything else you said, everything seems to be fine, especially with the date lines. We need to focus on why that relay is that way.
All 3 clutch position sensor wires have continuity to the proper pins on the ECM X2 connector:I noticed you're talking about the gray wire. That one is also spliced with the fuel tank pressure sensor and clutch pedal. So I would check both the tan and gray wires in your clutch pedal connector to ensure they have continuity.
That is really odd.... You shouldn't see anything hardly when it's not activated. And 9.6 on it is not enough to excite the coil to activate it. You may want to trace it back to the ECM and verify that is what is coming out of the ECM.It reads 9.6v to both frame ground and pin 85.
I don't have anything small enough to go in the pin from the backside of the ECM connector. It's a single continuous wire from the ECM plug all the way to pin 86. Other pins in the area read battery voltage.That is really odd.... You shouldn't see anything hardly when it's not activated. And 9.6 on it is not enough to excite the coil to activate it.

Hey, it's a good idea. Unfortunately the relay actuates when supplied battery voltage, and swapping the relay has no effect.I agree that 9.6V is an odd voltage; however, it doesn't automatically mean the ECM is bad or that there is even a problem at all. I've seen weird voltages before on circuits that I thought I were having an issue with, but that ended up being nothing. Not everything in the overall circuitry is either 12V or 5V. Don't get too hung up on the 9.6V being your problem. It is interesting though.
Dumb question. Have you tried swapping that relay?
I might take you up on this if I can't figure it out here pretty soon.If you want to pull your harness and pack it up with the rest of your electronics we can fix it and send it back to you.
It's an 09 SS/TC. I just bought an ECM on eBay and some key blanks on Amazon. Appreciate the offer though. Hopefully the procedure here to erase and reset the keys will work (and the car starts). I'll keep trying things until the ECM shows up.I have a spare P12 ECM but I don’t know what car you have and it it takes the same ECM. Also not sure about if the BCM will accept it and allow it to start. Anyone?
Yep, I called it the key reader in the above post, but yes I checked all those and everything was good.I have a feeling you've already done this, but have you checked the theft deterrent module connections? Should have two power pins, a ground, and a green low speed data wire.
