Having some trouble with my 94 gs 300 , its all stock throwing code 14 which is igniter signal circuit malfunction. If the car is cold and the ecu has been reset it will crank and run ok until it gets warm throws code 14 and cuts off then will not crank back up . Because I have them laying around I've swapped in a known working igniter , ecu, and coil pack with no success. Any other suggestions ?

 

Check for continuity from ignitor wire to ecu with a volt meter
