pcm issue..no data link
the van is an e-350 super duty...2005....with a 5.4 engine..not a triton.
.the van quit running in traffic with no warning and had it towed home.... hooked up my code reader and there was no data link with the pcm... all fuses were good... did some checking and determined the pcm was bad....got new, preprogramed pcm and now the same thing...no data link....hope someone has an idea what to check for next Thanks!

On my 2005 E-350 with 5.4 engine the DLC is powered by fuse F2.26 (20 amp) of the Central Junction box or inside fuse block. Physically check the fuse for continuity--no visual check.
