Fuel pump codes

[Zrussian13]

Hey guys. Put 1500 miles on my TT car with no issues then today as I got into boost on the way home I lost all power and had to limp it off the road. Checked codes and had P00C6, P025A, and U0109. Car fired back up a few minutes later but 10 minutes down the road did it again but only the 2 fuel pump signal codes came back. I wasn't in boost this time. Car has stock fuel system with dw95s and jms bap. Car fired back up again so I can get it home hopefully. Fuse is good.

Could it be the bap causing this? Or any other ideas? I think I'll disconnect the bap temporarily to try and rule it out. I can think of anything else that would cause it to all the sudden loss power to the fuel pump module.

I think you are on the right track

Update: made it home yesterday and checked everything out. All connections to the bap and fpdm were good. Ground looked good. I disconnected the bap completely and drove about 20 miles yesterday and 40 more this morning. Issue hasn't returned. I started just creeping into boost and started getting into it harder as I put more miles on it. Afr looked good through out. I'll reach out to jms today to see what they think.

I searched the internet last night and couldn't find a single thing involving jms baps having issues on any make or models. Had me second guessing myself. It definitely seems as if it started happening as soon as I hit the trigger imput voltage. (About 2.4v) I guess time will tell now.
