Hi Im new to subaru's and have a problem with my 95 wrx.
It starts first time from cold everyday but warm it up, for example go to petrol station turn itof fill it up go to start it won't start leave it for 5 mins starts ok. Any help greatly appreachiated.

 

Does the starter still turn over the engine?

Any other characteristics? i.e. running rich, missfiring etc.

 

crank sensor faulty.. classic signs..

 

crank sensor is it easy to change? how much is it?

 

it is very easy to change.. look at the front of the engine and it is below the alternator between the drive belt.. has a 10mm bolt holding it and a couple of wires on the plug.. there is a similar looking one under the oil filler which is the cam position sensor. They are magnetic and with age become weaker.. you can remove and clean with WD40 or similar and it should work again for a while..
worth cleaning then both... just don't muddle them as they are different.

Not sure how much they are new.
