So heres my dilema....
Every day my car cranks perfectly, but lately in houston its been about 40 degrees outside when i get up for work. When i go to my car it doesnt start, it cranks and cranks till the battery fall dead if needed lol but no start.
Perfect story
I wake up today at 4am to be at work by 5am and i go outside to crank the car and its about 35 degrees crank but no start. I get home at 2pm its about 48 degrees now and it fires right up. Its been doing this lately so i go ahead and start my backup car knowing that my infiniti wont start on real cold mornings. Ive even tried jumping it with another car to see if it was my battery just cranked but never starts. Like its getting no fuel, i hear the fuel pump when i turn the key but no start. I have a 05 g35 coupe manual.
Any Ideas.
Before the comment "Put it in the garage" comes, I stay in apartments and i would hate to pay an extra 100 a month for a garage for this problem.

Quick Notes
40 degrees and below outside car wont start. 45 degrees and up outside fires right up.

 

I live in NJ and when i wake up for school its in like the high 20s yesterday it was 14 degrees when i woke up for hockey i have no problem starting it

 

i understand that everyone isnt having the same problem i just want a solution

 

Not sure if it would help you, might wanna try putting a Bottle of Gas Anti-freeze in your gas thank.

It shouldnt freeze but its just weird that it works good when the temperature is warmer :S

 

gas anti freeze never heard of it.wont hurt nothing huh?

 

is it turning over? do you hear the starter ?

 

Wonder if it's a crank angle sensor problem

 

its turning over just no vroommmm lol
i hope its not a cas problem i had one mess up on my eclipse and it was a pain... but when it went it went....this really goes by the temperature outside... and i know that sounds stupid but thats the only thing i can put together, when cold no crank when warm up vroommmm

 

I live in Austin and I haven't been having this problem but I know of friends and family who have had similar problems it turned out to be there Battery, you know since Texas weather is so unpredictable it goes from 30deg to 70deg over night this can mess with your battery. You might not notice any diff. when you turn the key but what is happening is the battery is not sending enough juice, try getting it tested.

 

It's the battery. Probably getting too old and not being about to put out enough cold cranking amps. 35-40 is really not that cold to have any affect on the fuel.

 

thanks.. i was considering a red top anyway.. but wouldnt jumping it from another car work... i had my civic hooked up for about 15 mins and i just gave up... but you are the second person to say something about the battery... i like to start a solution...cheap to expensive lol

 

Try 5 deg here in Chicago my G sounds like she wants to kill me everytime I start her! lol

 

Cheap Solution for battery
1. Autozone free testing on batterys
2. Just curious but have you checked your cables to see if they are getting any kind of spark. (Tool-Timing light) Or you could just unplug one of the cables and put a philip screw driver to the tip of the cable to see if it is getting any spark.
3. Tell your G a bed time story then put a blanket over it before you got to bed. LOL

 

seriously on step 3 no joke... i was gonna buy a car cover and test out that method... imma have to take the battery out for a test at autozone.. ive seen a diy for battery removal i just gotta find it.

 

i dont think its the cold i think its the crazy change in houston from low 30s to high 50s in a couple of hours... Last week it went from 74 to 37...
