bad ficm

  1. 6.0 Motor problems
    Hi I have a 03 6.0. Just put 3rd alt on new bataries. The truck would not start and shop said it was ficm. Just had them rebuild it and bump to 58v. With the key on the ficm reads 54 and while cranking it drops to 9 volts. The truck was towed to my house and I'm stuck. Please please help
