I have an intermittent no bus issue that stops me from getting fire to the coil packs. Can I get the pin out for the PCM connections?

Here are the network (Data Bus) diagrams (1, 2), the PCM connectors and pinouts. And I'll post the PCM wiring next. But on diagrams 9 and 10 you could check at the Data Link Connector when the fault occurs for either a solid 12 or 0-volt reading, meaning a short to power or short to ground.

Here are the PCM wiring diagrams if needed, page 1 (diagram 1, 2 top and bottom) and so on.
