Help, just broke down :(
94 WRX STi.
Was just on my way back from Zen, and I broke down! Waiting for a tow, so thought I'd burn some time.
Chap at Zen used a voltage meter on my lambda sensor, that was all. The cable running to the sensor wasn't pinned back up (The cable had been hooked over another object before. This is no fault of Zen's) so looks to have fallen down near the exhaust, and a black cable has melted. I could smell something, and just had a total loss of power until the car cut out. Now when I try to start the car, it just turns over. You can usually hear a clicking noise when you turn the ignition on, but I can't anymore? Would the lambda sensor have shorted? Or a fuse blown, or something severe?? Bollocks!! The cable that was melted looks connected still, just now exposed. Help!

Anyone know if there is an English fuse legend for a 94 WRX STi? Possibly blown a fuse: "the problem is going to be one of the fuses in the fuse board under the dash to the right of where your knee is when you're driving. I don't know off hand which one it will be and your fuse legend is most likely in Japanese, but from memory it's a 15 or 20amp fuse. The reason for the fuse blowing is the O2 sensor has a heater inside it so one of the wires to the sensor is +12v, and is shared with the injectors etc."
Or shall I just check em one by one?

Fuse box under the bonnet there are 2 square green fuses can't remeber which one so check them both but when one blows it stops the fuel punp priming and gives the symptons you have listed just swop with the other to get home as this is just for electric windows etc

Revisited those fuses as my electric windows were still working. Swapped the fuses again, and the car started.
Sounded rough tho!
And some new lights on the dash :S
So I recorded the error codes:
http://www.youtube.com/watch?v=XRqpZXpdb9c
24 and 44?
24 Air Control Valve or Circuit (Exc. Justy)
44 Wastegate Duty Solenoid (Turbo Models)
Are these bad?
Going to see if Parrs have that fuse tomorrow.
Also, what is that first light on the left?

This is the fuse mate looks like he has 4 available I would buy them all coz you never now when they will be available again nothing worse when your car wont start without it.

Gonna replace the O2 sensor and fried wire. Put up a post in wanted. I believe my car has a later version waste gate solinoid. V4 or something. Didn't believe there to be a prob with the wgs before, so not sure why I get that error code now. Maybe the short has something to do with that? Could the short also bugger the map on the car? As I said, the car seemed rough when I started it yesterday. Any thoughts? Will post up a video in a while.

Check this video though.
My Wastegate solenoid is making a terrible noise now. Can you hear the hissing? Coming straight from it. edit: Does anyone know from the video which version STi this WGS is from? I believe it's not the standard V1 STi.

Could someone confirm if this will be a suitable replacement wastegate sensor?
http://www.ebay.co.uk/itm/NEW-Oxygen...item3cb6c8d62a
And would this be the correct O2 sensor? My current is a 3-wire.

Fried is not the word! Just cut all the fried wiring out (over a meters worth!), replaced, and the car started. Tick over is high, and a loud hissing is coming from the induction kit (I originally thought it was the boost solenoid). I'll replace the O2 sensor, in hope that cures the problem. Fuse turned up this morning to. So far so good.

Sounds like you have a vacuum leak there causing the hissing and high idle, could also be giving you the boost solenoid code .
Also replace the lambda as soon as possible

Been doing some reading up.
Starting to worry about what the fried cables may have damaged.
Alot of people report high idle to be MAF sensor fault. The cable to the Lambda has fried so far up that it was close to the cables for the MAF.

Cables to the MAF sensor look sound though. Hadn't melted.
Could the O2 sensor cause the car to idle high when warm, cause the induction kit to hiss, and also on cold start, the car struggles to hold its own, I have to press the accelerator peddle to stop it stalling, it really splutters alot.
Could the ICV be affected by the short?
Awaiting sensor to arrive. Am praying it cures the problem.

Right, new (2nd hand) O2 sensor fitted, and after a jump, the car started.
Tick over once warm is around 1100-1200rpm and it hiccups constantly.
http://www.youtube.com/watch?v=Nmc1a...cAJTRMqdnEfFXQ
Still getting error codes 24 and 44
And my battery is now dead. Took the car for a good 3-4 mile drive, went to start it back up 5 mins later, and dead. Just a new battery required I guess? And a new Idle control value?
Or is the map screwed? Is that possible? I didn't try boosting the car. Should I drive it and boost it to see if it performs how it should? It seemed to drive normally under normal driving conditions.
Thoughts??? Fecking thing lol
