hi there...

having trouble with my 95 wrx import wagon!
it starts first thing then if i stop at the shops or somthing then try to start it again it doesnt start!! it then takes about 10 goes to get it started!! (once left it over night and it started in the morning)im not sure if its the alarm/immobiliser... ive done a diagnositic check and its coming up fault 11 fault 23 and fault 24!! could these be old faults? and not cleared?

i know fault 11 is the crank sensor! 23/24 is maf system..

thanks in advance
