I am new to subaru but, I have checked fault codes.

cam shaft sensor
crank shaft sensor
Throttle sensor

MY 95 wrx wagon is standard and starts first time from cold, but after a few stop and start runs it sometimes wont start.

Which sensor do I change?
I would very much appreciate any help on this matter.
Thanks

 

You MAY not need to change any. Are you following the warm start procedure, which requires not even the slightest touch on the throttle before turning the key, otherwise flooding will result?

I normaly follow the warm start procedure.
It is like its not getting fuel when it wont start. When this happens it it will sometimes go when i give some throttle.
