Its been really freakin cold!!! Like in the teens cold and last night I parked my 87 4runner outside, and In the morning it wouldnt sart at all, just kept cranking, any Ideas? keep in mind it has new fuel filter,injectors, spark plugs, wires cap and rotor, and I even have a deep cycle battery

 

Cold start injector not functioning? And/or cold start injector timing switch. It would not fire even after a minute or two of cranking?

 

Are you using synthetic oil? I live in PA and my 86' 4Runner used to have a hard time starting up during the winter, so I starting using synthetic and usually has no problems.

 

the deep cycle battery is probably the problem. i'm assuming its cranking slowly?

regular car batteries are designed to provide high amps for a few seconds, and dont have the ability to supply loads for long periods of time. deep cycles are just the opposite. The characteristics of the battery are based on how far apart the internal lead plates are, and how thick they are.

your deep cycle has the ability to provide enough amerage when its warmer to start, but not when its cold. batteries are most efficent at 80 degrees fahrenheit, and decrease at low temperatures.

 

buy a battery blanket/heater pad and an oil pan heater pad.

 

hmm, see what "cca" your battery has.
my optima i think has 800 cca

 

Pretty cold here in the Gorge as well: Freezing Cold Issues. The rain all day before the temps dropped into the single digits didn't help either.
Maybe some moisture related issue, bad battery cable connection, coil wires or frozen water in the fuel line.
I usually check the wiring first.

 

alot of people forget you can get ice in your fuel which will clog any fuel line if you have any moisture in your tank. a little heet goes along way!!!

my chevy had that exact problem and manifested in the same no start scenario, ecxept it was at the airport after sitting for a week, in -15 weather!!

 

thanks to everyone I will attempt some more tommorow

 

I just realized I spelled start wrong (sart) forgot the T haha!!! Ya I was really cold I spent ten min in 15 degree weather

 

yeah man its way cold here i spend more time on YT than wrenching!
if it is your battery get an optima mine has NEVER given me the slightest bit of trouble

 

I have the non-deep cycle Interstate battery in my 4runner and it is great. it has been in the teens around here too and every morning it fires it up great. I also run synthetic oil. I am using Rotella T Synthetic 5w-40 diesel oil (blue jug) Been quite happy with it. It does help quite a bit with the cold start ups.

 

Does your truck have a block heater? Or is that only for the Canuck models? Check behind the grill for a cord.

 

No block heater, it usually just rains around here. Its gonna snow again tonight so another day with out my baby, well I still have my 95 but its not the same

 

where you at?

 

yeah, got to have a toyota get together sometime.

 

My locks keep freezing. I can only ever get the passenger's side unlocked.

 

ya it has definately been cold out here.
the only problems i have been having is that its been alot harder to get in reverse i have to jam it in there pretty hard the first time.
and whenever you washingtonians want to meet up i am in. my friend took his runner up to elbe the other day and got stuck in the snow!

 

yeah that would be cool. i just barely got my trail rig goin so im down for somethin whenever

wd40 in there

yeah im in too so lets get somethin planned

 

X2.

I stick the hose of the WD 40 into the lock, and they just load the heck outa it. Fill it till it flows out, then work the key back and forth. You wont have an issue.
I do it to all the trucks at my place.

My e-brake keeps freezing shut! I HATE IT
