Question about 2003 Jeep Liberty
High resistance in the secondary will cause the coils to have to work at there maximum capacity causing coil failure. Use correct wires, spark plugs, gapped correctly also check engine grounds.

For coils to burn or melt indicates excessive current flow through them
have voltage checks done wiring as there may be a problem in the ignition module that is allowing excessive current to the packs

Could be a faulty fuel pump. As the pump warms up, when you have a faulty fuel pump they will tend to seize up. When it fails check the fuel pressure with a fuel pressure gauge and see what it reads.

This is a common problem with all cars, If you do a search on sulfur and fuel gauge problems you would find more info than I can tell you.
But basically you will need to replace the fuel sender in the tank to fix this problem.
The sender uses silver contacts and the sulfur is corrosive to it.
The sulfer in fuel changes thru the year and sometimes its extreme.

replace the busted transistor in your ECU. For Bosch 30011 or 30014 you can use BU323Z transistor for replacement. it´s 100% pin-compatible and released for transistor ignition systems.

A code P0305 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using Fixya, and have a nice day.
