Ive been having problems starting my 2000 F 250, and now it wont start at all. The past few days its been cranking slow and it took a little longer than it should to start but it usually started, last night I put in a new starter and now it cranks plenty fast but it wont start at all. I had the batteries checked and they are good. A Ford tech told me that if I have 10.2 volts or less the computer wont let the injectors fire. Both batteries were at 12.2 but when I crank the motor the driverside drops to 9.8 and the passenger side stays the same. If anyone has any input Id love to hear it, I honestly have know idea what to do, oh yea the truck is sitting at a park and ride right now, going to get my buddy to drag it home for me if I cant fix it there. Thanks in advance
