I am still having the cold start problem but I dont have a fuel pump pressure tester to hook up to the fuel line. It just occured to me that this problem only happens in the mornings and never in the afternoon or early evening. I am thinking that this could be temp. related. In the morning it is hard to start on the first try but this never happens later in theday when the car has been sitting from 9 am to 6 pm. Is there a cold start circuit that could cause this problem?
