Car won't start on cold mornings?
hey guys, i've been havign this problem for a while now and i can't seem to find the problem. if you guys can help that would be great.
when i try to start my car in cold mornings, whish isn't even that cold, prob from 12 degrees to 15 degrees, it won't start. i can't hear the fuel pump starting whirring and starting up. but later on in the day when it gets warmer, it works again. first i thought my fuel pump was dying, so i changed it, and teh same problem occurs. i checked my ignition coils, and checked spark plugs which all seems to be fine. the main thing is, when it doesn't start, i can't hear the fuel pump.
if it matters, all i've done to my motor is basic bolt ons, with ngk iriway spark plugs, and i just replace the fuel pump with a oem replacement fuel pump.
Thanks for the help everyone.

When I start my car I listen for 2 things : fuel pump relay goes "click" and fuel pump comes on.Check your manual or search fuel pump relay.Let know what u find out.

thanks for all the help. the battery is a optima yellow top put in about 5 months ago so i don't think that is the problem.
