Appreciate any suggested guidance, first time posting.

Quick summary: car stalled on freeway. Wouldn't start , dealer said bad fuel pump. Bought CJ motorsports billet hat, and npt tap for front damper. Aem 340 pump.

Pulled fuel pump , test original pump with 12 volt source and it still worked. �� drilled ventri based on cj tech guide. Put all back together ran fine 100 miles then stalled again , no fuel pressure. Reading zero. When cranking reading zero and doesn't bump at all.

What I did : test ipdm , fuse has power both sides, fuel pump power supply getting power at terminal and power to relay as well. Checked power to hat getting power as when when cranking engine. Can hear pump prime and turn on during cranking.

Any suggestions on how to solve , can regulator in house be bad, car only at 50k. Should I just go to return fuel system ? Trying to avoid more cost, but would like to confirm or solve the issue. Thanks again for ideas
