Cold Start Issues

JerZeyStangz · Dec 29, 2009

What's up guys,

I have a cold start issue with my car every time it gets really cold, its was under 20 Degrees Fahrenheit today. The problem is that when I crank my car in the morning in extremely cold weather, it will crank forever. The battery is very strong, and alternator is strong as well, less than 2yrs old. You can do this like 4 times and it will just crank. I hear the fuel pump prime, crank and the car wont start. Now here is the kicker, when I tap the gas pedal to open the throttle plate, the car starts and turns over easy. This happened to me last year but once. This leads me to believe that my Idle Air Control Valve is possibly going out? I just want to check with you guys before i drop 50-100 bucks on a new IAC. The car has 93k on it with the original IAC, never been cleaned to my knowledge, and it does surge in the morning slightly when warming up. I do not want to clean it and end up having to replace it anyway...

thoughts?

It takes like 10 mins to clean?

Yeah but when you live in the tri-state area in January, you do not want to be outside for a second.

Well I lived in MT in -50degrees so I hear ya. I'd start off with that and an oil pan heater too.

Yeah maybe ill take it apart and clean it. we will see. Do not really want to because I think they usually have a good life span then once they go bad, just need to be replaced.

Op, what kind of engine do you have and what if any mods.
The reason for a 5.0 not starting may not always work on a 4.6.
It could be something as simple as a tune up. plugs, wires, air and fuel filters, clean the maf and iac, cap and rotor for the 5.0 guys.

whats all done to the car?

Everything is tuned up. New plugs/wires/fuel filter/Air filter everything. Mods: cai/mid-pipe cat-back. The car is 96 GT with the modular motor. The maf is clean. I never touched the IAC which lead me to believe that is teh culprit.
