RedSuns · 10-30-2002, 03:37 PM

Ever since it began to get cold up here it takes me a really long time to get my engine to initially start in the mornig...i am not sure of the temperature outside but it is COLD....also my coolant lines are still running thru the throttle body.....any ideas.....

nrcooled · 10-30-2002, 03:40 PM

What does it do when it doesn't want to start.  Does it sputter or just not crank make a whailing noise like a banchee (sp?)

More info please

RedSuns · 10-30-2002, 03:42 PM

it will just turn over-and-over-and-over it will take about 2 minutes until the engines catches and fires up......when it does fire up if i touch the gas it will try to die......

adey · 10-30-2002, 03:52 PM

So you actually mean it will turn and turn and turn, but won't turn OVER until about 2 minutes worth of cranking has been done!?  That doesn't sound too good. Are you using a proper weight oil for the weather? are you getting fuel/spark?
When does it stop sputtering?

Yoshi · 10-30-2002, 04:16 PM

on a side note; did you install the engine yourself? or did you have a shop do it?  Inquiring minds.... <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt='

RedSuns · 10-30-2002, 05:32 PM

i put the engine in myself and ever since it has been running great but is just hard to get started in the morning(after sitting for 8 hours).....it will crank it for about 8 seconds then sit for a few seconds....then try again...after a few times of this is I will completely shut everything off....wait a few seconds then try to start it 3 times.....then all of a sudden it just fires up real quick then sits at about 1800rpms until the engine has warmed up a bit

DuffMan · 10-30-2002, 05:58 PM

What weight oil is in there? If it's 15w50 than that is probably causing it.

drift into a curb · 10-30-2002, 11:22 PM

Is it the starter? distributor? spark plugs?  It cranks, but it doesn't fire up eh?  I dunno, but that's definitely not a good sign when you're sitting there, cranking the thing.  I would avoid doing that if possible, find another car to drive until you fix your problem.

Check these things:

Wiring to IACV (black w/yellow stripe i believe)
IACV itself
Injectors for leaks/dripping
Wiring to MAFS (ground)
Coolant temp sensor

Ummm...can't think of other stuff...tired......

It's not the oil.  It's something fuel/air/spark related.  IACV has a big function in cold start.  If it's not operating or clogged, you won't be getting proper air at cold start.

nrcooled · 10-31-2002, 05:59 AM

After doing some research try this:
Turn the ignition to the "on" position and leave for like 2min
Then try to crank her up

Edit: That will pressurize the fuel system.  It may be fuel pressure issues for cold cranks

GamblerZ · 10-31-2002, 07:27 AM

I think you should DEFINITELY check the following:

oil weight is too heavy to crank engine
poor spark(fouled plugs?)
poor fuel pressure(clogged injectors or fuel filter?)

I did like the suggestion above about "pre-starting" the fuel pump to prime the system pressure.  I will have to remember that for the future.

Just curious, what part of the country are you in?

is it alright to run 10W-30

RedSuns · 11-01-2002, 03:58 AM

so far i think it is my IACV(i am wrong on this...i think right now)......ahhhh toooo much beer.....but my idle has always been weird......i got my BOV to close at idle...and it has been cool ever since....but it got cold so i still wonder

uiuc240 · 11-01-2002, 09:32 AM

how did you get the BOV to close at idle and still blow off?

Well how cold is it there? I don't know where you live. If it is the IACV it should start right up with a little bit of open throttle. Does it?

RedSuns · 11-01-2002, 10:44 PM

when it is above 50degrees the engine fires right up...but once it get colder than that i have to crank on it for a while until it fires.....i have the turbo XS h34 BOV...you just stack washers into it and it will close at idle

mbmbmb23 · 11-02-2002, 08:19 AM

I used to have a car that would die when you floored it.  Reason being was that one of the cylinders would always foul out the plug.  Sounds to me like your air/fuel ratio is outta-whack.  Do you smell gasoline shortly after trying to crank it for like 20-30 seconds?  Have you changed your fuel filter lately?

*drifterx* · 11-02-2002, 09:01 AM

i have the same problem ..... my  injector s r leaking

RedSuns · 11-02-2002, 02:35 PM

i do smell gas after 20-30 seconds worth of cranking......but.....the engine ONLY is hard to start if it is real cold outside.......if it is any bit warm it will fire up real quick.......

i agree with inercooled.. i doubt other factors b/c of that fact u say it only happens when cold

RedSuns · 11-03-2002, 01:04 AM

i will try that.....but i only hear my fuel pump when i first turn the key on then it shuts off in 2 seconds....i know why it shuts off but is the pump is nit pumping then how does it keep pressure on while i just sit there......
