...allowed to cool for 30 minutes? The petrol pump has been replaced but there is no change

have a diagnostics check run

i had a similar problem with my honda accord..
mine was a electrical problem with a rely switch

here where my car symptoms. VERY HOT DAYS car would not start unless i rolled down the windows let it cool for about 30min to1hr
while driving car engine would just shut off ...than i would let it cool and it would work again.

to fix the problem i went to every backyard lil repair shops and all had different ideas of what was wrong , from the water pump to fuel system spent probably thousands over the 3 yrs i had it never want to take it to the dealer so they could look at it , afraid of how much it would cost for them to find it.

but in the end i bit the bullet went to the dealer they found the problem in 5hr and cost me $300..

so my advise is don't be like me and waste your time and money trying to guess what wrong take it to the dealer

Because it's malfunctioning, and wants to be checked out by a qualified technician.

I'm right and you know it.
