Pick up the distributor cap (don’t let any wires come off) and take a look inside it. Wipe the inside clean with a lint-free rag. Do you see any cracks in the cap when you hold it up and shine a light through it? If you do, you can buy another cap very cheaply.
What happens when your distributor goes bad?
Your car keeps stalling: A failing distributor can prevent adequate voltage from reaching the spark plugs. Since the engine needs that spark to run, a bad distributor can result your car stalling when it idles.
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.
How do you check voltage to distributor?
Unplug high tension wire from coil that goes to distributor and insert a short spark plug wire. 3. Turn the ignition on and check with test light or volt meter at the battery side of the coil to make sure you have proper voltage there.
How do you check the spark on a distributor?
Pull the coil wire from the distributor and hold it near a ground. Again, have your assistant crank the engine and look for spark from the coil lead. If you have spark, you likely have a problem with your distributor rotor or cap, so you may want to replace them.
How do I know if my distributor timing is off?
Symptoms of incorrect ignition timing are poor fuel economy, sluggish acceleration, hard starting, backfiring, or “pinging” or “spark knock”. Too little spark advance will cause low power, bad gas mileage, backfiring, and poor performance. Too much advance will cause hard starting and pre- ignition.
How do you find the number 1 on a distributor cap?
The surest method to find number one is to remove the 5-8 rocker cover. Turn the engine over by hand, until you notice number six valves are on the rock, exhaust just closing and intake opening. Number one will now be in firing position and the rotor will be pointing to number one on the distributor cap.
What problems can a bad distributor cause?
Common signs include engine misfires, car not starting, the Check Engine Light coming on, and excessive or unusual engine noises.
Can I spray WD40 in my distributor?
Turn off the vehicle and spray the spark plug wires and the inside and outside of your distributor cap with WD-40. Using WD-40 to repel water from spark plugs, distributors, alternators, and batteries is a good way to prevent corrosion and keep moisture away.
Can you clean a distributor?
Step 1: Plug-Out the Cables- The first thing you need is to locate the distributor. Step 4: Use Contact Cleaner- Spray some contact cleaner on the internal contacts of the distributor cap. Step 5: Dry Out- If you have a compressed air source, apply the compressed air through the cap.
Can you fix a distributor?
Luckily, most distributors can be rebuilt, unless they are damaged or weathered beyond repair. Your car’s distributor sends the flow of high-voltage electricity from your coil to each of the engine’s cylinders. The cables connected to each contact carry the voltage to the spark plugs.
