hello-i think the cold start injector (solenoid?) is fired from the ecm on that year-may be wrong, don't have wiring diagrams at home. i think if you pull the coolant sensor harness off, that should fire the cold start injector when you crank the car. could be a misadjustment or improper eha readings, too. sounds like a 3rd party should look at it. good luck, chuck.
