today in brisso its 33 degrees (feels like more)
for the first time evar today my skyline wouldnt start after a lengthy drive during the middle of the day (to get tyres and intercooler quotes), the petrol tank was full but after lots of driving it was half emptied today
we got home and wifey went to start the car and it wouldnt turn over
plenty of clicking and wirring, no ignition
when she got out of the car there was a loud (easily audible) sucking noise from the petrol tank cap
the other day i had to open it because i could hear the pressure behind it
she did the same
there was a loud rushing of air sound and when she retried starting the car started straight away
this sounds like vapour lock to me
is it just because its so hot today in brisso and we used so much fuel?
do i have a tank breather hole blocked?
the car is midway between its 100k service (all the easy stuff done, the timing belt and a few gaskets, plus cooling fan are being done on monday)
should i mention it to my service people?
