A faulty engine distributor won't spark, which will either prevent the engine from starting or cause it a running engine to fail. ... The distributor also disburses current to the spark plugs initiating engine performance.

Will a car run with a bad distributor?
A faulty distributor cap can cause your engine to stall. Voltage must be produced by the spinning distributor rotor for the engine to keep running. If the rotor does not rotate properly, the engine loses power and stalls out as you're trying to drive. The longer you let this go on, the worse it will get.
What problems can a bad distributor cause?
In comparison with modern cars and their solid-state ignition systems, the distributor has to be one of the most infernal parts of an older engine. If not regularly checked and maintained, it can cause all kinds of problems, like poor starting, misfiring, low power and, er, being stuck on the side of the road.
Can a bad distributor cause loss of power?
Bad spark plugs, fouled-up plug wires or a cracked distributor cap can cause spark loss, while compression loss -- in which too much of the air-fuel mixture flees a cylinder before going bang -- commonly arises from a leaky exhaust valve or a blown head gasket [sources: B&B; O'Reilly].
How long should a distributor last?
The distributor cap, rotor and spark plugs could make it longer, and were often replaced at the 30,000-mile (48,280-kilometer) tune-up. Spark plug wires held out the longest, with a recommended change at around 90,000 miles (144,841 kilometers). By the 1990s, distributorless ignition systems were becoming more common.
Do distributors go bad?
If you do have a vehicle with a distributor, you might have a very rough idle, low power and stalling if it was worn out. Fortunately, distributors do not go bad very often at all. Most people change them to get better performance out of their engine.
What sends power to the distributor?
The distributor has a shaft that gets spun by the camshaft. That moves other distributor parts that cause the ignition coil to pulse, and sends the electricity down each spark plug wire in order. The power travels down the spark plug wires to the spark plugs and causes sparks.
What happens if your distributor timing is off?
Ignition timing retarding causes the spark plug to fire later in the compression stroke. The effects of retarding ignition timing include reducing engine detonation, which is combustion inside the cylinders after the spark plug fires. This is also known as engine knocking.
What does it mean when your car feels like its losing power?
There are many reasons why your vehicle may be losing power, especially when accelerating. Some of these common causes are: Mechanical problems such as: Low compression, clogged fuel filter, dirty air filter, clogged Exhaust Manifold. ... Malfunction of actuators such as: Bad injectors, bad fuel pump, bad spark plugs.
What happens when your car loses power while driving?
The most likely issue is a clogged fuel filter. The purpose of the fuel filter is to ensure that dirt and debris stay out of the fuel system, so over time, it may need cleaned or replaced. When the fuel filter is clogged, the fuel pump has to work much harder, resulting in a far less efficient drive.
How often does a distributor need to be replaced?
According to most service manuals, replacing the distributor is recommended on most domestic and imports every 50,000 miles at a minimum.
When should a distributor be replaced?
Replacing the distributor cap and rotor at the same time should be completed every 50,000 miles, regardless of whether or not they are damaged. If your vehicle does not put on a lot of miles every year, it's also a good idea to replace them every three years.
Do I need to change distributor?
It is recommended to replace distributor cap and rotor at the same time you are having the spark plugs and spark plug wires replaced. The cap and rotor contacts will wear down just like the spark plug electrodes wear down over time from the high voltage going through the electrodes.
