Engine shut off while driving and won’t start.

ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

ANSWER : Hi there:

The symptoms you’re describing above could be one of several different problems; ranging from serious internal engine damage caused by the lack of engine oil for an extended period to simple items such as a malfunctioning crankshaft position sensor that might have caused your engine to shut off. Although you might be short on finances, the best way to save money is it have a professional mobile mechanic come to your home or wherever your Acura is currently located and have them complete a car is hard to start inspection first. This will allow them to pinpoint the source of your starting issue and recommend the right repairs. If the damage to the engine is severe (which is a distinct possibility) their initial inspection will allow you to make a decision on whether it’s better off to buy a new car as opposed to spending money on repairs.

ANSWER : Hi there. There could be two problems here. It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not have enough juice to start it again. Inspect your battery – it should have at least 12.5 to 13 volts to start your car, if it doesn’t you will need to replace the battery. The second problem could be that your alternator is bad and not charging your battery, in this case you will need to replace your alternator. Both the battery and the alternator can be tested in your car. If you would like to have the car checked for you, a certified professional from YourMechanic can come to your car’s location to diagnose the starting problem and proceed with repairs.

ANSWER : It’s curious that you don’t seem to have a code in the ECM. Usually if you have a malfunction that prevents the car from starting, there will be a code resulting. That being said, it sounds like you may have an issue with a crank position sensor or an ignition control module. Both of these have a history of failing when they are hot and coming back to life again when they are cold. A bad crank sensor will almost certainly result in a code, but an ignition module might not. It’s hard to say what the issue is about the door lock, but it is probably not related.

Both of those pieces are pretty expensive, so I don’t recommend just replacing them to see if it works. Your best course of action would be to have a mechanic check it out so you don’t replace anything you don’t need. YourMechanic can send a technician to your home to diagnose the starting problem firsthand and recommend an accurate fix.

ANSWER : Hello, thank you for writing in. The vehicle is stalling due to an electrical issue (typically pertaining to power supply or a sensor), a lack of fuel, or a failure with the ignition (spark) system. You will want to start by scanning the vehicle for diagnostic troubleshooting codes. Use any information found there to help guide you to the system or component that is failing. Without that information, you will want to test the fuel pump, ignition cables, spark plugs, and alternator function. Further testing may need to be done based on those results. For more help with diagnostics, contact our service department to schedule an appointment.

ANSWER : The problem sounds like the battery is too low to crank the engine and was most likely caused by the alternator not charging. You should have battery fully charged for at least 15 minutes and then see if it cranks over. You may need to replace battery and alternator. Have the system checked and replace these components as needed.

ANSWER : The intermittent no start condition you are describing will not damage the car. Obviously, though, an intermittent no start condition such as this can cause great inconvenience. If the symptom is no starter motor operation at all, it relatively easy to pin this down. The next time you experience no starter motor operation, hold the key in the start position and have an assistant use a voltmeter to check for battery voltage at the starter solenoid. If there is battery voltage to the solenoid, and yet no starter motor operation, you probably have a starter that has an intermittent fault. Sometimes, in these cases, if you strike the starter motor body sharply with a rubber mallet the starter will then work when you try the key. If striking with a rubber mallet works, that typically means there is a bad spot on the armature. The vibration from striking the motor simply moves the armature just enough to get it off the bad spot. Obviously, the solution is to drive around with a rubber mallet in your trunk. All kidding aside, you have some sort of intermittent fault and it will be discoverable if you request a no start diagnostic. Please let us know if you have further concerns or questions as we are always here to help you.

ANSWER : Hi there,
The problems you are having with your vehicle, may not be easy to diagnose. Apparently, under hood temperature and ambient temperature both create the no start condition. Components can act-up with temperature change. Assuming no check engine light is on. The no start condition will have to be duplicated and inspected at the time of no start. This will help identify what is wrong. So many things can keep the vehicle from starting. I recommend having the vehicles no start condition be inspected and diagnosed by a certified technician from YourMechanic.
