Hello Sam,
The P1301 code is related to Ignition Coil #1 Open Circuit or Short to B+. This code generally indicates a misfire or ignition-related issue.
So, I would replace the spark plugs and coils for all four cylinders if it passes the compression test which this guide can help with:

Here is how to change the coils out with the spark plugs. Clear the codes once completed. Check out the images (below). Please let us know what happens.

Okay I checked the compression dry and wet, solid readings. Switched out the plugs. Here’s my question: do I need to replace the entire DIC? Attached is a video of the part.

Okay, replaced the DIC. Engine started and ran roughly then cut off. Got it to start a couple more times with the same result. Now won’t start.

Hmm, yep, maybe the sensor is weak, and it causes false codes, here is the location of the sensor. Be sure to clear the codes once completed. Check out the images (below).

Just to be on the safe side, this is a Saab trionic for a turbo engine. Is there anything that I’m missing or not checking here?

Do you have the same code? (P1301 code) is you replaced the coil I would replace the spark plug as well, even if it looks good, I have seen them have hairline cracks. Also, is the electrical connector at the coils looks to be in good shape?
