Sometimes this happens when a heat shield is missing from a Catalytic Converter or muffler. If you have made modifications like engine changes or installed Headers you need to have some additional protection for the fuel system. If you restore missing shields it will help.

There are aftermarket products like Thermal mats to repeal heat or exhaust wraps which can reduce heat from an exhaust header. Some people have made fuel coils to place over A/C dryers and use the A/C to cool the fuel. It works, but really is rerouting the fuel line.

Old school tricks like attaching Wooden clothespins with spring clips directly on the fuelline,and putting fuel lines inside old A/C finned tubing are 2 ideas. They increase surface area and dissipate heat.

If the Air temp is 100 degrees the pavement is probably 130.

How to identify vaporlock.

Car running rough? Stalls at strange times but after a few minutes restarts? Could be vaporlock.

Vaporlock is more and more common these days as the fuels change and older cars are running on more and more ethanol. They simply weren't designed to run this fuel, originally.

So the easy way to tell if it's vaporlock is pop the hood once its stalled and pour some nonflammable fluid on the fuel lines. This cools them down and helps it restart. This is a temporary fix. A more permanent one is to get a heat shield installed on the fuel lines.

Technical Explanation: Vaporlock is the fuel boiling and the car does not properly measure it out then so the engine starves of fuel and stalls. The residual engine heat can keep it this way for many minutes.

The code P0601 means the internal memory of the PCM (computer) has failed self-test. The PCM may need to be reflashed or replaced. The other codes will probably go away after this.

It could be a vapor lock issue. Vapor lock is typical in older vehicles. With the invention of fuel injection vapor lock has been minimized. What causes a vaporlock is underhood tempatures causing the fuel in the lines near the engine to evaporate causing a vaporlock. Now once the engine cools down, it will condense back into a liquid eliminating the problem. Fuel injection uses a lot more pressure than the old carburators did. One thing you can do is try replacing the three most important fuel system parts. The fuel filter, the fuel pump relay and the fuel pump. You need good steady pressure to push the vaporlock out of the lines. If one of these three parts is malfunctioning then it will allow the system to vaporlock. As for the gusage readings, taht could be just a bad sending unit.
