Gas leaking from underneath car

ANSWER : Hi Ricardo. We answered your question earlier. However, if you didn’t receive the reply, here is what we stated earlier. In most cases, an EVAP leak will create an OBD-II trouble code. The best way to detect an EVAP leak is by having a professional mobile mechanic complete a check engine light inspection, they will be able to download the code and determine the source of the leak. That’s the best advice we can offer you. Thanks.

ANSWER : When an air conditioning refrigerant leak is being detected, a mechanic will often use an electronic leak detector that is specifically designed to ’sniff’ for a specific refrigerant. These electronic leak detectors are also made to detect fuel leaks. I would recommend locating a mechanic that owns one of these electronic leak detectors and enlisting their assistance in inspecting an oil/fluid leak. This would be the best chance at finding the leak considering that is is not large enough to be seen by multiple people.

ANSWER : Hi there. In most cases, an EVAP leak will create an OBD-II trouble code, which is the best way to detect an EVAP leak. By having a professional mobile mechanic complete a check engine light inspection, they will be able to download the code and determine the source of the leak. In most cases, it’s an EVAP purge solenoid that is faulty.

ANSWER : Leaking gasoline is a fire/explosion hazard so be sure to have this leak repaired at your earliest convenience. In the meantime, be sure not to park in a confined space, such as a garage, because gasoline vapors could accumulate and explode if there is an ignition source. Undercar fuel leaks are often caused by corroded, perforated steel tubing, joint leaks at the fuel filter, or rubber hose connections. Sometimes fuel pipes can get damaged by collisions with debris on the roadway. Whether the leak is in the steel supply and return lines, rubber hoses, or even the gas tank, it will be repairable. If you desire a repair of the leak by a certified Mechanic, dispatched by YourMechanic right to your location, please request a fuel leak inspection and diagnostic – tubing and tank and the responding certified mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : Hello,
There are a number of things that could make an engine noisy when starting up. Depending on the specific type of sound you are referring to, this will determine how to properly diagnose. If there is a bit of a hissing sound, this may be a sign of a vacuum leak. If this is more of a shrieking sound, this may be a sign of a worn out or out of adjustment serpentine belt. If there is a bit of a howling or growling sound, this may be a sign of a worn out or low on fluid power steering pump. A rattling or pinging sound may be caused by an ignition problem. An engine can ping (or knock) due to an improper combustion process. A "spark knock" is the result of combustion occurring too early. Early combustion can occur from carbon buildup inside the combustion chamber, a lean air/fuel mixture, and advanced ignition timing (spark plug firing too soon). A clattering type sound may be a result of improper lubrication in the valve train which could be a more serious problem and should be addressed as soon as possible. I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle to ensure everything is in proper working order.

ANSWER : Hi there. When you have an issue with start up that was "resolved" by adding a chemical in the fuel, that leads me to believe that either you have a fuel delivery problem (caused by a dirty fuel filter, clogged fuel injectors or throttle body) or an worn out ignition problem, caused by worn spark plugs. First and foremost, I would recommend AGAINST using a chemical additive to repair your vehicle (especially if it’s an ether product as this can cause a serious backfire and could create major engine damage). Instead, have one of our mobile mechanics come to your location and complete a car is hard to start inspection.

ANSWER : If the starter motor itself is not functioning (i.e., no engine cranking), then the starter circuit has to be diagnosed. If the starter motor is functioning, but the car is not starting, you could have a circumstance where the fuel pump overheated because it was run dry. That could cause the pump impeller seal to fail. First, check for the characteristic, but momentary, whirring sound from the in-tank fuel pump at key "on". If no fuel pump operation is detected at key "on", check for battery voltage at the pump wire harness at key "on". If no voltage is detected, that circuit has to be diagnosed all the way back to the battery to find the fault. If there is power to the pump, but no momentary pump operation at key "on", the pump would be condemned and replaced. If the pump does operates, check fuel pressure in fuel rail to confirm that it is operating properly and supplying adequate pressure. If you desire that a certified mechanic resolve this, please request a no start diagnostic and the responding mechanic will get it diagnosed and repaired for you. Please let us know if you have further concerns or questions as we are always here to help you.

ANSWER : Going by your description and the age of the car, I’m going to guess you have a problem with your water pump. The water pump has a rotating seal that often doesn’t leak unless the engine is running. If your water pump is leaking you might be able to see a drip from the bottom of the engine front cover. Before jumping to any conclusions though, you should have a professional pressure test the system to be sure. If you contact Your Mechanic. they can send a technician to your home or office to check out your leak and tell you what it will take to solve it.
