Recently purchased a second hand SM and powerlogger. Installed in my Limited and connected the normal way through the #5 spot on the analog block. Also connected a MAP reference at the analog block as well.
When key is turned on, SM displays SM 2.2 followed by PL but with no version and then promptly shuts itself off like it's suppose to when there is no signal. Wiggled the wire at the ECM and at the analog block and a couple of times I got a pair of 3 dashes like it was waiting for some info but then it promptly went blank again. Reseated the connector at the ECM and at the analog block but to no avail. Connected the USB to the computer and I get all the info to include the MAP input.
I was going to replace the wire coming from the ECM going to the analog block but haven't been able to find one yet and see if that would fix it. Also thought of connecting directly to the orange wire at the OBD1 connector but didn't know if the SM would work with the 2.2 chip installed, so I haven't done that yet.
Any thoughts on how to remedy this?
