Hey guys I have a 500hp civic and it's has a harder time starting when it's really cold outside (15 degrees) but after a coupls of trys it fires up when it's warm it tarts no problem. I am just wondering if this is normal for built civic?

 

Who knows? No one knows anything about your build other than it's 500hp.

 

Why are you running your 500hp civic in the cold? i have a swapped del sol i wont even run in the cold. Regardless, just do a quick check of all the normal things, (battery voltage, starter draw) But usually, older cars just take a little more to start up, especially heavily built motors.

 

I think the amount of power is irrelevant, but whatever. Does it make any noises when trying to start? ticking?

 

Does it try to turn over or is it just turning the starter?

 

Jeez. You haven't figured this out in two years?

Hahahaha

Anyway, it's cold out. Your motor is "built". It's fine. If it ain't broke, don't fix it.

check your voltage drop on your engine/chassis grounds. grounds grounds grounds! + i would like to see this 500hp civ

 

large injectors? probably

tuner probably used the injector modifier to make changes across all your tables to cut down the fuel at low/no throttle.

easy fix? yes! stuff a sock in the intake when you go to start it.. should help a little. or use starting fluid.

or change tuning to dump more gas at really low air/engine temps.

or just deal with the fact that it takes a few cranks to get the injectors to make enough of a gas puddle to allow enough burnable vapor to build up and start the car.
