Having issue with fuel system it appears. Stock fuel system, pumps, BAP. Car shuts off randomly. Pulled code 1233 for FPDM. First time issue happened, I let it sit an hour then it started and ran a few miles. Last trip ended up with a tow.
30A Fuse to BAP relay was popped, replaced. Relay is OK. BAP has 17 V output, so seems OK. Car will start and run but dies within a minute or two. Monitoring fuel pressure thru OBD, it is erratic. If it drops too low the engine dies. It will restart. Can hear pumps prime and run.
Are these symptoms of 18 yr old FPDM? that has been on higher voltage? Next steps?
