306 1.4 petrol won't start when warm - mfarrow
Hi

Mate's got a 306 petrol that won't start when warm (say after 2 hours). Will restart when hot (say 1/2 hour) and cold (say overnight). Will start though if key is turned back to zero, then try again. There is a petrol smell when turning over, while it refuses to start.

First instinct is immobiliser, but would the ECU continue to pump fuel into the engine? Second thought therefore is a sticky ignition relay, but why would this be temperature related? Third thought is cold-start-valve/regulator-thingy, but why would it suddenly work when ignition turned back off and on?

I'm puzzled.

Thanks

Turns out it would! An utterly appalling design in all Peugeot cars IMHO, what with the risk to flooding/catalyst poisoning. Why not just cut the fuel?

Anyway, new/reprogrammed key and all sorted now.
