11- crank pos. sensor
13-cam pos sensor
21-water temp sensor

subaru wants more than the car is worth for the replacements!!!! what the hell?!?!?!

this didnt happen over night did it?
crank position sensor is right on top right under the alternator
cam position sensor is on the top of the drivers side head, right behind the oil filler
the water temp sensor is a real bitch and from what i noticed goes out often or is easily broken, there is a water crossover water pipe under the intake manifold. the sensor is on the top back of that
idle air control valve, can be a couple different places depending on whether your intake manifold is is jdm or usdm. if its a usdm it would be on on the passenger side of the throttle body, if its jdm i think and i use that term lightly "think" they are all on the drivers side
the pressure exchange solenoid is under the intake manifold on the passenger side. if its the one i am thinkn about then its blue and super hard to get too. and its just above the fuel rail
can anyone back me up here?

oh and also you can try pulling out you crank and cam sensors and just try cleaning them. because the car will not run at all if they are not giving a signal to the ecu, but if they have a bunch of metal shavings or other debris then it can screw up the signal and cause shitty idling, and hesitation etc....also try to clean the crank sensor and cam sensor points on the cam gear and the crank gear

If it turns over and runs like crap or not at all when it's warm, I'd start with the coolant temp sensor. It's an easy replacement, just get a deep socket and it'll go right over top of the connector. Also, I'd suggest putting the car at a down hill angle to minimize coolant leakage.

i pulled out the crank and cam sensors and they where pretty gooped up, i cleaned em up and thier associated holes and reinstalled, car starts like 10% BETTER...still sucks ass when warm
but it pulls alot harder and seems far more powerful for some reason...wonder if the two correlate??
i need a cheaper source for parts though...even the local parts store has off brand ones for 250.00 and 175.00...gay

The coolant temp sensor will wreak the most havoc on how your car runs, so go to the dealer, pay the $35 for a new one, and replace it.
It really isn't as hard as they make it out to be, just get a good deep socket, an extension and a U-joint socket, and you are set.

well i replaced the coolant temp sensor and now the check engine light is either continually on or flashing
the car still will not start when warn...and now when i try to drive it it backfires and dies
also now it wont idle at all
the sensor was a factory subaru part
everything is plugged in
i reset the computer i think...pulled neg cable for a few mins
what the hell????

pull the negative cable and hold the brake for a couple of seconds and try again.
replace the spark plugs if you haven't. its cheap and never hurts. if the car has been running bad, it can foul them up pretty bad. and you might want to try swapping spark plug wires with a different car if you don't want to buy new ones.

plugs and wires have about 50 miles on em

That won't reset the computer. On a cold engine, pull negative terminal off battery and let sit for at least half hour off,or overnight. Press brake pedal down, hold for 10 seconds right after you disconnect battery.
Connect battery next morning.
Turn off ALL electrical components, lights, wipers radio.
start car, but DO NOT touch throttle at all. leave accessorys off.
let idle for 10 minutes. turn off car.
start car, drive, see if there is a check engine light code.

just curious, have you checked your fuel pump? next time you try a warm start up and it doesnt start. go to the trunk, pull up the passengerside oval corver over the fuel pump. and knock it a few times with a hammer or mallet er something. and then try starting it again. or just have someone contiuously tap it while you start it

Didn't someone have a similar problem a couple months ago? I think it turned out to be a MAF sensor.
Definitley make sure you reset the ECU properly. The neg batt cable/brake trick works the best in my opinion.
