Try holding the gas pedal down halfway then crank it. If it still does not start after 5 seconds, floor the gas pedal and let it crank for another 5-10 seconds. It it starts, let off the gas immediately. If it doesn't start, try a couple of more times with the pedal floored. If it still doesn't start at this point, then it has some more serious issues.

The engine will eventually throw a code. The code will more than likely tell you why it's not starting.

Most common are errors for the Engine Temp Sensor and crank/cam sensors. Check http://svx-iw.com or the howto locker on how to get the codes.

the dealer said it was cold natured. and didn't like to start on cold days. they are goin to try and get it to start tommrow and i am goin to go drive it. if it don't start i will try what u said.

That's the symptoms of a failing engine temperature sensor.

how much are them and how hard are they to put in? would that cause it not to start?

According to subaruparts.com the part number is 22630AA041 and it costs $20.54. Replacing it is easy.

will it still start with that part messing up? and would i have to take it to subaru to get it fixed?

When mine failed it would only start after cranking for a while. If I touched the gas pedal it would kill the engine. Imagine starting a carbed car with no choke and unable to pump the gas.

I would try the hard start procedure before assuming any part failure. Some SVXs are simply hard to start in cool moist climates, yet runs fine otherwise. Certainly there mut be somethings that aren't operating as well as when they were new, but not necessarily anything to be immediately concerned about.

well it is cool and wet from all the snow. so maybe that is just the problem. and the batterie was dead for a few days so a new bat and hopefully it will start.

A bad TPS or TPS that is not adjusted correctly will also cause a hard start. Holding the gas pedal down may get it to start if it's just a bad adjustment.

Holding the gas pedal down only engages what the ECM knows as the clear flood procedure. This is included in allmost all fuel injected vehicles program where you can clear a flooded engine ( excuse me).........Cut the injectors off from releasing fuel in an attempt to clear a flooded engine that seemingly already has too much fuel...hence, the flooded condition......

Now, I bet almost everything that I own that you have either a failed Cam or Crank sensor. I had a similar problem with mine where It would barely start and when it did start run like crap. It turned out to be the Cam sensor on the driver side of the engine. There are 3 sensors......2 for the crank and 1 for the cam. One of the cam and crank sensors is the same part number and the other crank sensor is a different part number. Try that....They are not cheap though and I ordered mine from www.subaruparts.com.

don't do that, especially that the car is in cold temperature... you will risk scratching the engine block especially that the oil is still cold... just pour a gallon of moderate heat on the radiator, then a hotter one... push the gas pedal twice and then take your foot off before turning the car... try it

Just give me your address and I'll be over to collect your things!

Actually, if you search the old Yahoo archives, you'll see that I and a few others have had hard start problems ever since 2000-01. All of my main sensors are working fine and the car runs perfectly once started. It's getting it started in moist cool weather that's the problem. There are several hypothesis ranging to expensive leaky injectors to something simple and cheap to fix like a dirty IAC valve. It has not been a big enough of a bother to me at this point to chase it down since I live in an apartment and they don't appreciate engine teardowns in the parking lot.
