Car Starting Problems

Some of the common car starting problems stem from a discharged battery, a bad fuel pump (or no fuel), a weakened starter motor, or a broken electrical connection. Checking each part will help troubleshoot why the car won’t start.

2002 Hyundai Senata just stopped running. Went over a speed bump and car just shut off. It seems as if car is not getting any fuel. Does car have a fuel cut-off switch somewhere?

More than likely it does. Most (if not all) modern cars have a shock sensitive switch to cut off the fuel supply in case of an accident. Check the owner's manual. It is probably on the firewall behind a trim piece. It will have a reset button to turn the fuel system back on.

How can you over ride or bypass the factory alarm on a 2000 Chevy blazer It causes the engine to start intermittently?

Factory alarms are, by their very nature and by design, difficult to bypass. It is almost a dealer issue, but some automotive locksmiths can help.

Why when you give manual cars a push they will start?

Most of the electrical energy needed to start a car is used by the starter. In fact, very little electrical energy is needed to produce a spark and fire the injectors. Usually an alternator can produce enough energy, even at low RPM, to provide power to ignition, computer and fuel pump. The total amperage of those devices may amount to anywhere between 1 and 5 amps. A typical starter can require anywhere from 75 to 200 amps, depending on the engine and starter condition. Pushing a vehicle with a manual transmission allows the engine to turn, replacing the function of the starter.

How do you start your 1997 Nissan sentra when you put a new starter alternator battery in and it won't start it makes a click noise and the lights and stereo still work?

Sometimes, brand new batteries need to be charged for a while before they have the power to engage the solenoid/starter properly. The battery may have enough jucie to light up the headlights and run the stereo, but not to crank the engine.

95 g20 is getting no spark what do you check besides fuses?

Few things. Check first of all the spark plugs make sure they don't need to be changed. Then it if they are in good condition that is not burnt or covered in oil/grease (if so that might be the problem change them) check the spark plug wires and make sure the spark gets to the end. But if the spark does show but it still doesn't ignite its most likely the timing. If no spark go to the rotor and make sure that's its in a good condition. Most likely its the sparkplugs or the wires less likely the distributor. Check them in any order you preffer. But my guess it would be the spark plugs

Can the theft deterrent system on GM cars be by-passed?

Supposedly there are bypass modules....some are so that the remote start systems can function with the security system in the car....others are just strictly to bypass the security system intirely. I have seen some websites that sell these modules such as Ebay but there are some more specific car sites that sell them too. I have read a few things on this recently and it looks as though GM has used the Passkey I, II and III systems. The year, make and model of the car depends on what system was used and what type of bypass you will need.

If I changed the oil and spark plugs on my 2003 Stratus now the car won't start and when I try to the oil light comes on the the horn won't stop blowing what is causing this?

Changing the oil wont keep the car from starting. Changine the plugs will if you didn't put the wires back on in the proper location. The oil light will come on until the car starts and allows the oil pump to fill the filter and circulate the oil. Once started, the light should go out.

What should be done if a 1963 Chevy truck will not start?

Determine the problem and see if you can fix it or not. If you cannot determine what's wrong then find someone that can. A trick to starting a vehicle is to pump the gas while you turn the key in the ignition. There are a million different reasons as to why a truck won't start.

Can a bad ignition coil cause a car not to start?

yes once the ignition control module heats up it would cause the vehicle to stall. usually after it cools down the vehicle will restart again.
