[QUOTE="I_LIKE_TURTLEZ, post: 1578418, member: 31555"] You're being guided down the rabbit hole, the codes are from the battery swap and disconnecting the MAF, ignore them. If the infamous inertia switch were triggered it wouldn't start at all, you have a failing fuel sending unit based off the symptoms. You need to check fuel pressure at the rail with a mechanical gauge with the car running and then let it sit off while you watch the pressure, it should bleed off very slowly over half a day, never trust scan tool data that's rule #1. Rule #2 is never trust wiring diagrams, especially from Mitchell1. Pure coincidence, when FSU's crap out it usually happens suddenly. [/QUOTE]
