what should i do to get it to run in all weather

 

more details, is it slow cranking or crank quick but no fire, could be any number of things without knowing more its hard to say

 

what does a slow crank mean?

 

no details?

No idea.

 

must have never been in the snow, ever have a damn near dead battery, its when the engine still turns over but barley fast enough, usually happens before the 'click click click' phase...

 

Since he gave no details, get a block heater. Find a battery with good output, or figure out some way to keep the battery warm. Dunno why those 2 things wouldn't fix most issues.

 

nope, never.

 

it happened to me too...just last night...seems like the cold weather siezed something in the enginebay (could be a number of things but i didnt bother to go see what it was...i knew it was something about the cold) so i just gave it some gas and tried a couple times then it fired right up....really random problem if you ask me.

 

how cold is it?

and it's not cold enough in SF to hurt the car.

 

if you're asking me....

cold ....like when the car has some frost build-up on the roof and the windows are frosted......if i can guess maybe around high 50 to low 60? somewhere there...

im in daly city...i dont know how it gets pretty cold during late nights...



and yeah personally i dont think it does anything harmful for the car.....if it never happened before...and it only happen when its cold out..then...i dont think it should cause any serious concerns...

 

naw, COLD is 36*, that's the lowest I've been around anyyways. I'm trying to figure out how cold these other gus are talking about.

 

ummm its 26 right now.. and.. it sucks.. but im out east too, and ive never had any issues with my vert even when it was 14 outside..
just cold as hell before it got warm inside the car...

 

It might be a problem with the water thermo sensor on the back of the water pump housing. The plug might be off or one of the two sockets inside the plug are pushed back.

When there's an open on that sensor, the ECU defaults to 176* temp which in turn means the fuel injected during start is too little if the engine is stone cold. See the attached chart.

It would help if you gave a little more information. IF the starter is just real slow in turning the engine over, then you might say so. Then the problem would be *another* thing.

 

the battery is new sparks r new it and i relocated the battery to back of the car it just wont start when its below 65 degrees and will start up with out a problem when its hot outside

 

65 is cold?!?!?!? Mine doesn't like to start when its 15 or colder. Just floods out the first time. But strangely starts after deflooding everytime.

 

lol at saying cold is 50 degrees. I wake up to 20 degree temps and my car is fine. So far, if it's anything colder than that, there's too much ice on the ground for me to even think about driving, so I'll just keep her at home.

 

Soo...

Does "just not start" mean it cranks, but doesn't fire? Or is nothing happening at all?

 

That's a classic sign of the water thermo sensor being disconnected. Look at the chart and you'll see why. If the sensor is disconnected, the ECU defaults to a water thermo sensor reading of 176*F. Looking at the chart you'll see MUCH less fuel will be delivered at that 176*F than at 60*F. Less fuel delivered on a stone cold engine reuslts in difficult starts. Once the engine gets hot though, the default reading almost matches the Real temperature of the engine and now it'll start just fine. As long as the actual engine temperature is hot.

I'm talking about the Chart/Graph in my other post. I came across that chart and finally figured how to keep a low compression engine from not flooding. I just tricked the ECU into not using the internal START FUEL map inside the ECU when the engine was actually hot. By not using the START FUEL map in the ECU, the ECU was forced to use the afm signal for starting, which results in a very low amount of fuel being delivered during START. But you didn't ask that, so just ignore this paragraph.

EDIT: About the water thermo sensor being disconnected. The plug may look attached to the sensor, and if it is, pull it off. Then look inside the plug and see if the two contacts inside the plug are *pushed back* or not. Ususally if this if the case, only one will be pushed back and you can easily see the difference b/t the two pins/sockets sitting side by side. I'm a little bullheaded about water thermo sensors going bad. That isn't likely at all. Very small voltage going thru it. It isn't going to *burn up*. If it has not been strunk by a hammer or the like, the sensor itself should be good. Just an open wire somewhere.

If you've been working on the water pump or alternator, then that is where you should look. At the plug on the sensor on the back of the waterpump housing.

 

you could just be flooding the engine because thats sometimes what happens to mine when it gets cold outside it flood and i have to remove the fuel injector cable under the steering wheel and put the pedal to the floor and start it and then connect it again and it start fine
