Help, won't start cold
I know it has been asked before but this has recently started happening on my car. If i let it sit overnight and it is a cold morning it will only give one quick sputter, not enough to get going. I can keep cranking it and it will not even give a shot from one cylinder. Yet if it is warm out it will fire right up after sitting overnight. If there is a faulty part I should be looking at tell me where it is so I can change it quick and tell me how to determine that is the faulty part.
Thanks in advance guys.

It's usually the DME temperature sensor that causes this cold start problem.

When it won't start, does the tach wiggle?
If so, check for fuel and spark, or follow Clark's guide

Below is a link on testing the DME temperature sensor. The only problem is that the test is at 59 degrees F, and it might take colder temperatures for your car's problem to show up. Worth testing though anyway.

how many cold cranking amps does your battery have?
how old is the battery? how are the connections on the battery terminal?

Biggest battery I can fit in there, the battery is 3 months old and the connectors are professional grade stereo battery terminals for the sound system in the car. It cranks over fine and no problem.

dont go by battery size. that wont tell you anything...
what are the numbers? your starter can go until the cows come home, but if you dont have enough power in your battery you'll just sit there and waste your time...

Well the car is outside and it is raining right now, I do know I got the exact one for the car when I ordered it thru NAPA. It has never let me down and I have high doubts as to the battery being the issue here.

alright...
but wont you feel like a goof if it is the battery?   i've got an '03 mustang battery in mine to battle the cold mornings.... my car starts the same in -20 as it does in 35 degree weather.

Just curious if you've tried testing the DME temperature sensor yet? But you need a multimeter to test the resistance. Also for the test values in the link I posted I think it has to get up to like 59F, not sure if it's getting that warm in Vancouver though huh?
But if you want, you could measure it and post the resistance value and the temperature when you tested it, maybe it'll give some clues

I need to pick up a new multi meter, no problem with finding the temp tho, I have a temp gun to accurately read the block temp.

there is a problem where the pressure regulators and/or the fuel injectors will leak and the fuel rail will empty out, this will happen slownly over a couple hourse or so usually and as a result you'll have to crank the engine for a long time if it's been sitting
by the way is you unplugg the dme temp sensor the comeputer will think it is full cold so if you're having a cold start problem and think it may be the dme unplugg the temp sensor and see if it starts, if it starts then you know the problem (by the way if you unplugg the temp sensor and the car isn't dead cold it won't start either, or if you start itcold with the thing unplugges and then the car warm up it will run like crap and die so this is just a test, don't actually drive like that) the locations of the dme temp sensor is on the top of the engine block near the upper right side of the belt covers as you look at the engine it has a 2 wire clip on connector that points up cali56 has a nice picture of where it is, i'll ask him to post it |
