Replaced the fpdm the other day. Had a rough start one morning, then no start the next day. Warmed the fpdm up with a heat gun and drove to the part store for a new one.
Hard to believe even that corroded it still had another "drive" left to give. Sent from my SM-G930P using Tapatalk
Turned out the real problem was relay 203 in the fuse box. Battery was draining down over a couple days and still had trouble starting. Replaced relay and no more issues.
