hi everyone,im new to the forum so go easy!
im also new to the subarus as im been a ford nut for years but just got myself a sti type r 3dr,its a beautiful looking car but one problem,i bought it as a none runner,i know what your thinking,why?? it was cheap as it should be being a non runner but after checking it out the cambelt hasnt gone,its got a spark and fuel,turns over fine and trys to start but just never fires up,so im thinking crankposition sensor?are these common for going?would this cause it not to fire up?
it hasnt got an alarm so its nothing to do with that,ive noticed the air intake pipe going into the turbo where it is rubber has split pretty much all around,would this also cause it to turn over but never fire up?ive ordered a new silcone item which should be here next week but i just want to know peoples opinions or anything it could be as ive never seen so many sensors on an engine in my life! im a fully qualified ford mechanic so checking,replacing anything isnt a problem,
any kind of advice,things to check etc i would be really gratefull as i just want to get it on the road!
finally sorry for boring you,the guy who i bought it off said he went over a speed bump and it cut out,prior to that it was running fine???so im hoping its something easy
thanks
dan

sounds like your fuel cut off switch if you have an accident has triggered

crank sensor or water temp sensor - just under the inlet manifold by the turbo. mine went recently and that was the problem. have you got the engine check light on?

OP says its got fuel & spark

orrr you could try and reset the ecu. that might work if it has a fault registered

Good luck

When you say it has fuel, do you mean the fuel pump runs? After trying to start it, have you pulled a plug out to check it's injecting fuel into the cylinder?

I would first check the crank sensor for sure. As this is more than likely your culprit.

But do not forget although you have spark and fuel there may be no compression. Check the compression while your at it as this could be the main reason why its been sold cheap.

Good Luck

thanks for replying,ive pulled of the fuel in pipe and when the ignition is turned on it fires right out so im thinking fueling is ok??

when you turn the ignition on, can you hear the fuel pump prime? it should buzz for 2 secs

dinnyd

thanks for replying,im presuming my engine light would'nt come on unless it was running? would the crank sensor or water temp sensor cause it to just turn over and not fire??
cheers

Not sure if the CEL light would work if not running!?

As STI Baly said - the crank would be the most likely culprit, but as I said my water temp sensor went and it REALLY struggled to get going. If yours is completely goosed it might not want to go at all.

dinnyd

compression check is my next job,im not really looking forward to it as the spark plugs seem something of a nitemare to get to! do you thing the fact that the intake pipe has split would cause it not to fire or would it just not idle?
also how much are the crankpostion sensors and where do i get one from?
cheers for replying

im going to check compression first,if ok il fit new crank sensor and water temp sensor,how much are they both?also wheres the best place to get them from
thanks again dan

Ebay mate. Water temp sensor about 25 and crank will be a bit more but only go for a new one.... or try the stealers but they will pull your pants down. Erm, scoobyclinic maybe?? Not sure if they do them or not

dinnyd

nice one mate il get onto it now
thanks again

try connecting the 2 black connectors to read any faults look here for any info what year is the car and the dash lights come on before you start if the cel light does not come on then the bulb has gone or been removed

if the crank sensor has "gone", then you shouldn't get a spark

to test is simple, disconnect the crank sensor, do you have a spark, if the answer is no, reconnect it -- now do you have a spark, if the answer is yes

then its a good guess that the crank sensor is working

try the same with fuel -- i think without a crank sensor it does not fuel too

i had a split pipe on my rs turbo and it wouldnt start till i replaced it due to drawing in too much air i think,r u local to essex

i had a fualty crank sensor which caused it too start only now and then

It may well be just the broken pipe to the turbo, I had the small pipe from the boost solenoid to the resonator come off over a pot-hole and wouldnt idle or even run properly.
took ages to find out what was wrong. lot of head scratching.

get your new accordian pipe fitted if you have already ordered it and try again if its still not running then move onto the sensors IMO.

hi mate no where near essex,im in manchester,cheers for the advice,going egypt in the morning so it can wait!
thanks again
dan

dinnyd
