Car will not start every time I try to start it, it blows fuse 9 for ignition coil/fuel injector 1 and 3. If unplug the ignition coil it does not blow the fuse. Has codes p0261, p0264, p0267, and p0270, also has codes p0599, p0351 and p2301.

The thermostat, ignition coil, spark plugs, and valve cover gasket have all been replaced along with new battery.

There was moisture in the electrical plug that goes into the top of the thermostat housing which has been replaced.

Good morning,

I attached the wiring diagram for fuse 9.

If you disconnect the injectors, not the module, does the fuse still fail? You may have a shorted injector.

The codes may have set from you turning on the key with the ignition coil disconnected.

The 599 is for the coolant sensor shorted high for the cooling system. Did you disconnect the sensor?

The 351 and 2301 are open circuit codes form the coil being disconnected.

Check all the attachments I posted below for the codes.
