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.

i have heard somewhere that this is caused by a faulty vacuum check valve which is black and white plastic and is located near centre above the rear of the engine up against the firewall. vacuum drops when you accelerate so there is not enough vacuum to keep various vacuum operated heating/cooling system valves in their selected position . the check valve keeps sufficient vacuum in a reservoir tank when vacuum at the engine manifold drops.

Hope helps (remember rated this) TY for use Fixya.

Turbo or non turbo engines are 2.3 liter.

check coolant level and valve to heater coil

take off pipe going to the intercooler from the turbo see if oil is found and clean then other pipe from incooler check it .if oil is found .drain oil in intercooler .you have an oil leak from the turbo this is why you will have light on far left of dash

The code seems to point to the camshft actuator circuit. Namely the Oil Control Valve. Probably needs replacement. I do not know the location on your vehicle. I suggest you ask a mechanic or try to find it online.
