So your fuel injectors are not pumping out fuel? because your throttle body controls air flow into the engine if your fuel injectors are bad they will read below 11 ohms

Ok I'm going to check that .But what about the fire no power to the coil so im getting no fire at the plug . Just wondering if my computer is gone cause both went out at the same time.

Not exactly sure about that sounds like maybe you had wires fry if they no longer have power but you would have smelled the wires burn if they did unless there may be a resistor or fuse that protects it from a power surge that may have burst but I don't have a clue.

Nothing wrong with wires I been all over this thing all fuses good. I don't know where the coil get gets it power from tracked the wires to the fire wall .but thanks for the info.
