Well you have two choices. Its either ECM or wiring. Would recommend you do check the "CAM RPM" via Black Box Logging to satisfy yourself that the cam and crank are in synch. Just cam pulses probably wont tell you this.Originally Posted by tk-mpl
You could try your 08 Silverado OS, or the Silverado ECM with VATS disabled.
how do you do "black box logging"?
Data Log using the V2 FlashScan only....

when I try to do that it sayes no pids selected?? do yo need a SD card for that??
No, there's ~ 2 MB of internal memory in the V2. You can just use that. You might need to create / update a PID group for your ECM to include CAM RPM though.
I "validated pids" and cam rpm still doesn't show up..
Do you have the latest V8.1.2 software installed? Open EFILive Scan & Tune, click Black Box Settings, uncheck the boxes next to the controllers you wont be using (since you're not using a SD card Id recommend only leaving the entry for your current car). If your ECM/TCM combo is not selected, clear all the checkboxes and press the red button to clear, then double click the first blank entry and select your ECM/TCM setup. PIDs will appear on the right hand side, simply find the ones you wish to use and double click them. Press the red Program button and the proper files will be transferred to your V2.

Cool, I will have to update and then try...
Sorry, that took awhile to figure out... I do have cam rpm..... I also checked every pin in both ecm conncector and they are all right and all in the right spot......
???
I think it is still that the PCM doesn't have a "crank or start request"

Ok that all looks good from that angle then.
With the crank relay pin C1 67 on the ECM grounded or through a resistor or connected to a relay then to ground plus VATS disabled do you still get no coil or injector status as "on" or "off" when cranking?
Fuel pump primes ok for 2 sec at key on?
