Fuel Pump must be bad

[Ted Best 2]

I swapped out the Fuel Pump Relay and it still won't start if the temperature gets warm. So i'm assuming it must be the Fuel Pump. if i turn the key when it's warm i don't hear the fuel pump. can anyone explain why it's only affecting the pump when it's warm?



Also can anyone refer me to a good site/brand for Fuel Pumps? They seem to range in price a lot. is there really a difference?



Thanks

Do you hear whining when you turn the key to the run position (not start but run)?
