Check the thermo time switch to see if it's working, pull out the cold start injector on the intake and point it into a clear bottle (fuel spraying on spark plugs wires is a no no) it should spray a fine mist for at
least 5 seconds solid. If not, when the car is cold, check for power at the connector with a noid light or a test light in the connector with some one cranking the car. If no good, unplug the thermo time switch and check for power at the black/yellow wire when the key is turned on.
