V6 or 4-cylinder engine?

Any reason to think the gas was bad?

 

has the fuel filter been replaced
maybe looking at a faulty fuel pump

even a faulty gas tank cap seal
does the cap wosh a bit as you undo it before filling

 

It is a V6, gas cap replaced. Have not replaced the filter, not sure why the filter would cause a problem when filling up?

 

toyomoho has mentioned bad fuel from a filling station

this car no start .... has happened straight after filling the tank

possible symptoms of bad gas . are something trapped in the cars petrol filter stopping fuel flow

could be
fine particles of rust from the ground tanks .. water from condensation.... or stale fuel.

if the filter checks out ...... then there will be another cause . and will need investigating

 

If you suspect bad gas, throw some dry gas in there first. It will take care of mild impurities.

 

If your Camry is hard to start after refueling every time and starts normally all other times. Then first try this. Once you finish fueling, make sure the gas cap is tight. Turn the A/C switch to max cool. And the fan switch to max also. Then as you are cranking the vehicle slowly press the accelerator gradually to the floor. Then if it catches and starts but you have to continually pressing the accelerator to the floor to keep it on. Then it is one thing. It is your fuel pump located in the tank. Replace the whole assembly or most importantly the pump inside the assembly. But make sure it’s the exact pump for your vehicle. When it happened to me I had a Chk-Eng light too. Once the Assembly was replaced the light went out and car ran normal. Good luck!
