Question about 1993 Ford F150 SuperCab

1 Answer

Truck will not start when its hot.

My 1993 Ford F-150 XL 4.9 doesn't want to start when its hot. When I get in it in the morning, it starts fine every time. At lunch, if the weather is too hot with the sun pounding on it, it won't start. It never did it in the winter months. Now that its hot it does it almost every day. Although, when I park in the parking garage at work it starts fine. When it doesn't start, sometimes I hear a buzzing sound coming from the power distribution box, when the buzzing stops my truck starts. Sometimes it buzzes, sometimes not. Sometimes it takes 30 seconds to start, sometimes 30 minutes. I opened it up and felt the fuses and relays and it feels like the fuel pump relay is the one making the buzzing sound, even after replacing it. I have also replaced the plugs and wires, coil, distributor cap, rotor, and the ignition module

Ethanol fuel in hot weather will vapour lock easier than the old non-ethanol fuels.
Maybe that was all it was.
I get the calls ........usually from shopping centers on very hot days on cranking but no start cars.....and it is 80% just a vapourized fuel problem. TOO HOT FOR THE FUEL UNDER THE HOOD.
The cars start the next morning....or late in the evening.

Checked battery and charging system and it was fine


A simple load test on your current battery will tell you if it's the battery. Double check all connections are clean, tight & in good shape. Usually autoparts places, or garages will test it free.
