most of the time the car starts but on a VERY hot day the car cranks but wont start, sounds like the fuel pump isnt going on, i changed fuel pump but no help... anyone got any thoughts of what the problems is? =(

check your main relay...car not starting on a hot day and fuel pump not priming is almost ALWAYS due to a bad main relay.
