Hi. Have had this problem since I bought the car. After car sat eg overnight and the temperature is low the car will not start unless I repeatedly turn the ignition on/off and pump the throttle pedal, after that it runs fine when started. Here is a list of parts replaced-
Fuel Pump, Thermostat, Engine Temp. Sensor, Crankshaft Sensor, Camshaft Sensor, MAF, all Vacuum/Breather hoses, Fuel Filter, Throttle Position Sensor, also cleaned the Throttle Body.
Lately the engine will not start after the engine has been off for a short time, it turns over then dies, but if you pump the throttle it will start, sometimes it will backfire.
Any help/ideas will be gladly welcomed. Thanks. Jim
