My mach died while driving and pulled a p1237 code after towed home. Thanks Triple A. Next morning, no fuel pressure and don't hear the pump. Here's the weird part, I put on the battery charger keep the battery 100% charge and for the fun of it, I turned the key and the fuel pump purred and got fuel pressure. Started up fine and now I can't do the FPDM test by jumping the pins. So is it the fuel pump or the FPDM?
