Hi welcome to just answers my name is Ricardo. is there another code following P1300 ? is the engine flashing on and off or steady on?

Expert:  Ricardo Hohl replied 2 months ago.

Unplug the igniter and turn the key on and check for approximately a 5 volt reference from the computer on the IGF wire (Black/Yellow (B/Y). Also look for any broken wires by the igniter connector located on the passenger fender under the airflow meter area.

see if the negative side of all of the ignition coils is getting pulsed consistently to ground. Verify ignition coil connections and good spark from all coils a bad coil will cause this problem with the igniter.

Verify the crankshaft position sensor has a good consistent AC voltage signal. Also if the crankshaft gear is loose or has damaged teeth the signal will be erratic and cause a erratic IGF signal and can cause a code P1300.
