My Plymouth Gran Fury engine shuts off on the highway. It has no power to the starting system. What happened?

One likely issue could be that the ballast resistor for the electronic ignition system burned out. This is a common point failure. That is why many owners keep a spare ignition ballast resistor in the car. Another design drawback on this vehicle is that the starter relay often fails. This relay is unique and is wired in series between the ignition switch and the starter solenoid. Its purpose is to reduce the current through the ignition switch start contacts when the starter is activated. There are also three terminal, cylindrical, time delay ignition relay on that car. If this relay failed, it may have cut off power to the ignition switch. The ignition can also fail if the distributor ignition pick up unit develops an internal short; or if the ignition control module goes bad; or if water from a big puddle gets into the alternator or the distributor cap.

My battery goes flat every time I leave my Plymouth Gran Fury at home for like a week. Nothing is switched on as far as I know. Any idea why is this happening?

This is a common problem not just with Plymouth Gran Fury but with any other vehicles out there. But for Gran Fury, there are a number of possible reasons why it happens. First, the Gran Fury has several permanently live circuits—not least of all the headlamps motors. This is a relay switch, so the actual live circuit has low power but it is still on. Second, liquid acid cell batteries lose a portion of their ability to hold charge in cold conditions, so they need to be kept topped up all the time. And third, the standard alternator is technically speaking not that useful. The regulator seems to fail at an amazing rate so the chances are that the charging voltage is not enough to maintain a good charge in the battery. The best way to fix this is to have it replaced with a new model.

I noticed rusts particularly at the front of my Plymouth Gran Fury. I am just wondering how I acquired it since I bought it two months ago.

You'd better visit a Plymouth Body shop to give your Plymouth a mop and polish. However, mind you, those rusts you have were caused by iron or steel dust in the air thrown up by various machineries. For sure, the rust you got is either at the back or at the roof. Those parts pick up dusts the most and are where particles usually settle. It can and does happen with any car, not just on your Plymouth Gran Fury.

This is reasonably easy to rectify. The rust particles are on the surface paint. These are not on the metal beneath them. You can clean them off! Get a clay bar and follow the instructions to remove the surface defects. After this application, you can put on a quality sealant or wax. This is fairly quick and easy and makes for a pretty smooth surface after waxing. To prevent rusting, simply take this necessary steps: First, bathing, then surface prep and polishing, followed by protecting (this is where you would apply wax or sealant or both to prevent rust) and finally, maintaining.
