My truck receives a good voltage reading from the ignition switch and battery to the coil. It does not seem like there is any wires burned out. Do you know what the orange ECU box should be reading so I know if it is good?
Do you
have the same problem?

Check your ballast resistor on the firewall what happens when it goes bad is the car will try to start on start position on ignition switch then shut off when you let off key. Check pickup coil for air gap.008-.010" and for ohms 150-900 ohms if out of range pick up coil is no good. Finally check coil at positive and negative if 10 volts on both the control unit is bad.
