Question about 1992 Ford Ranger
It sounds like this a dangerous situation. The engine may be using the fuellines as a ground. This would be like putting an electric spark next to gasoline. You may have another wire laying on the gas line somewhere. Check your Ground wire to the block.
The obvious thing to blame is the fuelpump, but there is both a fuse and a Relay to blow out. If these are not blown, the power that is heating the fuelline is coming from something else. The Fuelpump fuse and Fuelpump Relay only protect the Positive wires and there is nothing to protect the Negative wires. The Fuellines would be Negative ground and Unprotected.
Since your truck is not running, I would try a tool to check the Starter draw while cranking. Since Electric flows to the path of least Resistance, the Starter may have more resistance than the fuellines. You may have to take the Starter into Autozone or Oreillys for tests. You may have a short in the Alternator throwing a Positive charge to the Chassis
There is no telling what may have been Zapped if the Chassis got a Positive charge. Listen to the Fuelpump to energize before you use the Starter. There is an Inertia sensor which has a Pushbutton to Reset, probably under a Kickpanel.
Would like to know the outcome of this.
