Hi there , i,m hoping someone can help me , yesterday night when i was going to pick the wife up , my scobby would,nt start , turns over but does,nt fire , after a couple of trys i gave up and could smell petrol under the bonnet so i was thinking that i may of touch the accelerator when i first started it thus causing it to flood , anyway tried again after half an hour and got it going but it was really sluggish to start , went to work in it this morning no problem , come home no ploblem but when i wanted to go out tonight it would,nt start again , now i know i never touch the accelerator this time and got the petrol smell again, no matter how many times tonight i,ve tried its still not starting , anyone got any ideas has to why its not starting but smells strongly of petrol thus thinking its flooding , could it be coolant temp sensor ?

 

hi i had this prob on my 95 wrx when it was hot it would not start was ok after night would start ok. it was the cam shat sencer its just b side thr altanate and held on with 1 ten mill bolt i got 1 off ebay 4 40 pound but did not fit had 2 mod it then it was ok and it is still working fine i was told a new 1 was about 120 + 80 2 fit when i went 2 my subaru deler

 

i was told it was the temp senser from heaps of people so i get a new 1 on mt car but turnd out it was the crank senser

 

Smell of petrol is simply because it's not igniting. If it were the temp sensor, then it give different symptoms.

As suggested, either a crank or cam sensor is duff, which means you get no spark. With intermittent fault like this it's a bit of a pain.

Hopefully someone here will have info as to which sensor gives ecu the go ahead for ignition. First off though, have a wiggle on the sensor wires and plugs (each in turn then try the car). This may highligt a fault. If you do both at the same time, you'll be none the wiser as to which one may be at fault.

 

thanks for all your help , problem not come up since i posted but i,m going out tonight to pick the wife up , if it happens again like last time then i,m getting a new wife as my other baby does,nt like picking her up ,i,v just ordered a temp sensor for £31.85 + vat so will fit that anyway but will go looking for a crank sensor now on ebay , i,ll keep you posted cheers
