its been getting real cold around here (mornings are like 20 degrees) and now the car wont start.... i'm not sure where to start, the starter turns over strong, battery is new, so thats not an issue...

only thing i have is when it was about 40 degrees the car kicked over with no problem.. any idea? when its cold it will crank and crank.. but wont kick over

cap/rotor/wires are newer

any suggestions would be helpful.. getting a ride everywhere sucks.


ps: would fitv or iacv have anything to do with problems starting? thanks in advance

those are the first things you should check. FITV fast idle thermo valve, need i say more.

 

I don't seam to understand, how would the fitv or iac cause the engine not to start?

 

what kinda battery? try jumpstarting it on a cold morning and see if it runs.

thats what i have to do sometimes

 

definately not battery, i had it hooked up jumpstart style and didnt go still..


gonna check the fitv and iacv tomorrow

 

I have a very similar problem. When it gets below 40 degrees my car wont start unless I give it gas. It wont crank over with out giving it gas. But if I hold it at 2000 rpms for a minute or two it will stay on. It sounds like the motor is being choked without giving it gas.

So suggestions for me are to check the <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by bluedlude &raquo;</TD></TR><TR><TD CLASS="quote">

But IDK where that is at?

 

possible bad coolant temp sensor? when i had cold start issues last year, it was because i'd completely broken the plastic connector on the sensor itself, so the ecu wasn't seeing a sensor at all. had very hard cold starts as a result.

 

is the coolant temp sensor on the thermostat housing? i'll check into that.. i have noticed that the past year my coolant temp gauge never reaches 2 bars(half way) it always reads 1/4 no matter how long i let it idle

 

check out this post, the CTS is circled.

 

just went to check.. coolant temp sensors are all hooked up... wouldnt start.. its about 39 deg rt now...

 

have you tried resetting the ecu? I used to have the same problem with an old accord of mine when it got cold, and I would just reset the ecu and it would crank and run fine after that.

 

You need to find out why the car isn't starting. Is it spark or fuel. Probably spark, my guess. Test your ignition coil, see if the resistances are proper. Do a cold test on coil, because I found my coil tested within specs when it was warm(car was starting fine), but when cold, its resistances where WAAAAAAAAAY off (@-10 degrees Celsius and would stall out 2 or 3 times if it would even start).

Also, make sure the connector of the coil (4 Pin) has all the Pins pinching tightly on the slotted contact points. Even pinch them closed with needle nose pliers to make sure they bite down on the contact. Make sure the wire going to the secondary coil is making good connection. (this applies if your H23 external coil).

I have a 2 year old piece of shiet battery, and a new coil. Car fires up immediately, first or second crank every morning now.

(I'm sure you already know but) You can test for spark by having a buddy crank it for you while you hold your spark wire boot near a part of your block (that's grounded) using insulated needle nose pliers or equivelent ). If a bolt of lightning comes than your problem might be fuel than. Main relay perhaps?

 

Hmm... Alternator? Thats whats wrong with mine

 

good lookin out.. an extra coil and igniter layin around so i guess i'll give that a shot too

keep you guys posted thanks for the suggestions

 

update for u guys.. went to fire it up and fired up no problem first try.. wtf! i'm gonna be swapping coils/plugs and cleaning the fitv just incase.. this is truly baffling


ps.. its about 29 deg rt now

 

Intermittent problems are a b*tch.

So you didn't really do anything to it the night before? even remove/reconnect connectors or anything?

 

i didnt do anything.. just went out and started it... ok i just got done changing plugs/coil/ignitor and cleaning fitv

keep u updated tomorrow morning .. its gonna be a cold one

 

also what viscosity oil are you using?

 

using 10-40..

update

1 degree this morning.. same crap! cranks but no start again..
