Bump.

For the people who dis EFI, there's a reason that there are millions of vehicles on the road with EFI. They run like a charm and when they don't, you're generally not left crying on the side of the road. The ECM/ECU goes into "limp home mode" (LHM) so that the vehicle can still be driven but (in theory) won't damage the powertrain in the process.

I'm very happy that I came across this thread. My CEL/MIL came on today and prior to this thread (and the one by SpudRider) I had no idea of how to proceed. Thank you (most of you) for helping the OP (DoomHead) move to solution so quickly. In my case it was as simple as reseating the connector where the harness plugs into the fuel pump. Which I disconnected last week for some reason. Which explaines why the CEL flashed a Morse-code of P0230 0-:

IMO this was the worst type of technical problem: operator error. Doh!

BTW, SpudRider did a great writeup of the Delphi EFI system. Curious that he wrote it back in 2015. I thought that my 2021 X-Pro DLX EFI was all "new" tech.
