if i park my car outside overnight it never seems to want to start up like it is not getting fuel or something, but if i park it in my garage it will always fire up 1st crank

sometimes to get it to run i will have to crank numerous times before it attempts to start and will sputter around then die.
eventually i get it started then the car is fine the rest of the day til the next morning.

i already changed fuel filters, and put gas treatment in the tank but it still does it.


any ideas???

full tank of gas as well

maybe a slight decline where the front of car is down but nothing major maybe a 1-2 degree slope

also overnights are like 60-75 degrees

and i have a new interstate 900cca battert so that isnt the issue.

This one is easy.

Clearly, you have one of the very rare and sometimes sought after female V's. Truth be told - there aren't any females, of any make, model, or breed, that like to start in the morning.

You can paypal the $.05

Maybe that is what is wrong with mine! See my post Help#2
Once it's done cutting off/on it's fine

what would make the car not start in such humid conditions??? i just left an overnight project i was working on, the car is full of morning dew and get in an try to start the car and it sputters around etc... or will crank forever but will not start


finally after about 40 tries it finally starts and then if i do get it to run or move it will sputter and die, until eventually something happens that makes the motor think it is ok to give fuel or correct the condition somehow


Would a new MAF help?? i never did replace that??

Does that point where it starts running better happen at 131 degrees engine coolant temp?

Thinking you may need to tweak the cold-mode air:fuel ratio a bit; just like a choke in the good old days.

i will check that next time for sure


olda, i am not sure if that is it due to once it get started for the day it never has issues the rest of the day until the morning or condensation/humidy can get it for 7 hours or so later

just checked the other morning and that is not the issue,

it seems like it is back firing into the intake when trying to start, you can hear backfiring etc.. like it is flooded with fuel or something when trying to crank it up as it smells really rich. ??????????
