1989 Chevy Celebrity 4 cyl Two Wheel Drive Automatic 230k miles

It seems when the ambient temperature is above 82ish degrees F, the fuel pump doesn't work -- no whirring, no engine start (cranks, but won't run). In cooler weather, you can hear the fuel pump whir and the car starts right up. What is the issue, but more importantly, what is the fix (other than only using can in less than 80 deg weather)? Thanks for any help or insight.

Hello,

Relays have a tendency to fail when hot. I would suggest Checking the Fuel Pump Relay. It is located in the engine compartment on the passenger side front by the cross bar. There should be 4 relays there and counting from right to left it will be the 3rd one. Check out link below for testing....
