cold start issue

[thehank2000]

OK so i am new to all of this i have a 97 gst and i have problems starting the vehicle in the mornings when i have to go to work around 5 am. It normally takes the vehicle about 2 to 3 seconds for it to turn on once i turn the key. Sometimes i have to do a second try and it will turn on. i already replaced the wires and plugs new air filter. The fuel pump and ingectors are about 2 years old and seem to be working fine It dosnt have this problem once it gets warm, it will just start its not that bad now but im sure it will only get worse any ideas to help a new DSM'r thanks

What's the temp like outside and what's the cold cranking amp rating on your battery?

You probably need to get a new temp sensor. If it's too cold the temp sensor doesn't give the correct reading to the ECU which is not giving the correct additive of fuel it needs to turn over.
