Its on a charger now. I'll add PCM volage and injector ms then resend.
Module voltage is dropping way down and I cant seem to get much more than 100 RPM out of it. I might need to get a new battery or the starter could be weak.
Here is the file from the other ECM I have. Going to run to the shop and grab a serious charger. Trying to avoid running to town for a starter.
it has a P1336 code fyi
That may be similar to a 315 code for a GEN 4 but I think it can also mean irratic crank / cam
The Junkyard ECU or the one I have been using? Could that mean Timing chain?
First thing is get a good battery in the thing. Voltage is WAY too low during cranking. Battery is junk.
It's an old battery, been in my Nova for about 5 years, probably has less than 1000 miles on it and sits on a battery tender 99% of its life.

Here is cranking with a jump pack. Still drops to upper 9v lower 10v
OMG please take some advice and put a battery in it. I don't want to look at another log without a new battery powering it.
And still only about 125 RPM. Gonna have to bite the bullet and get a new battery and starter, it will be a few hours. Where do you find the DCT's in the log?
I think it's on the details tab.Quote:

It would be 58 tooth or 24 tooth. Do you know what year/donor your engine came from?Quote:

Sensor from the car has no numbers, just a blue dot. Probably a cheap parts store brand. The other one I have is an AC Delco part but it does say China on it, looks like its the wrong one though.
Getting beyond my knowledge, but I don't think I would chase crank sensor to far at this point. If you can see the reluctor wheel with the sensor pulled, it might be worth a look at it and compare to some online pictures to confirm 24x or 58x. But I would think that since it is registering an rpm, the sensor is ok, at least for now. But I'm guessing about this.Quote:

Having trouble with attachments again. I'll try again later.
Not impossible someone previously put a 58x in an older motor. But a 58x would show up as higher rpm and not lower rpm.
