Hi, thanks for writing in. You would be correct to assume that the issues your Lincoln is experiencing is most likely caused by fuel delivery. In most instances, the precise issue may be caused by clogged fuel filters, a fuel pump that is starting to wear out, or the fuel injection nozzles or throttle body that is dirty and needs to be cleaned. If you need assistance performing any of these services, feel free to contact one of our local mechanics who can inspect your town car issues and make the required repairs for you.

If your vehicle won`t start, it`s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you`re dealing with a battery or an alternator problem.
The most common reasons a Lincoln Town Car won`t start are a dead battery, an alternator problem, or failed starter.
When your engine cranks but won`t start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating compression. The most common causes are problems in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter).
First, it could be possible that your battery has power, but not enough cranking amps. Second, it`s possible that the ignition cylinder or ignition relay is damaged. Finally, the starter relay or starter itself is broken and would need to be replaced.
Connected to the battery is the alternator, which works to generate power for your vehicle`s electrical components. When you have a brand-new battery but still can`t start the car, the alternator might be the issue. Cold and damp climates may increase wear on an alternator, causing it to fail.
The car wasn`t driven long enough for the battery to recharge fully. The vehicle charging system has a problem, like a bad alternator or voltage regulator. An electrical system was left on, draining the battery. The battery is too old and just can`t hold a charge.
Sometimes this can just be a temporary failure and the vehicle will all of a sudden begin to work again. Possible causes of a power failure could be either bad battery connections, a bad ignition switch, or a bad alternator. What you need to do is check your vehicle`s power sources.
A dead battery is the most common reason why engines fail to start up. A common reason for batteries to fail is drain. Your car`s battery typically expends a small portion of its storage to start your car up, and then recharges from your alternator as you move.
If you don`t hear clicking when you start the engine, the problem may be a dead battery. If you hear clicking, but the engine doesn`t crank, the starter might not be getting enough electricity. Using your owner`s manual and a voltmeter, you should be able to test functionality.
If you`re unable to start your vehicle, check and see if the headlights and dash lights come on. If they shine bright and clear, that means that the battery and alternator are likely not the cause of the problem. If they were, there wouldn`t be enough power to run the lights.

I changed the fuel pump and truck ran great for 3 days. Now after 3 days, the truck dies. It will start running for a few minutes, then dies like before.
ANSWER : Hi there, thanks for writing in. I’d be happy to help. It sounds like you should disconnect the connector to the fuel pump and inspect it for any signs of getting hot. The female connections may be too loose on the fuel pump and lose contact after running and getting hot. If there are indeed any signs of problems, then I’d suggest replacing connector and adding dielectric lube to pins before installation. This should solve the problem, but if you continue to experience issues, feel free to reach out to us for help again.

Installed new delphi fuel pump and fram fuel filter. still no pressure on fuel rail valve and wont start. 2003 Chevrolet Tahoe
ANSWER : Hi there – I suspect you have weak power getting to the fuel pump. I would first check the voltage coming out of the fuel pump relay. If the contacts in the relay are burned, you will not get reliable current flow to the pump. Check the fuel pump ground as well (voltage drop across the ground, not just continuity). I recommend a fuel system inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

My truck died while driving. Now will start, but dies when I push brake. If I start in neutral, I can put in drive and go but dies – 2003 Ford F250
ANSWER : Hello – your symptoms suggest that once your cold start features are no longer needed – engine warming up – there is an air "leak" that ruins low speed running. Causes could be a leaking exhaust gas recirculation (EGR) valve, or leak in the air intake. A failing fuel pump relay (burned contacts) could cause similar behavior, contacts become hot, then won’t pass enough current to run the pump. Failing pump can also act this way – gets hot and fails. I recommend a starts, then dies inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

Cranks over start than dies
ANSWER : Hi There,
The idle air control valve is a small valve on the engine’s intake system that reads the air intake as it comes into the motor. This is controlled by the car’s ECM which uses this information to make adjustments to the air/fuel ratio depending on various inputs such as outside air temperature, intake air temperature, load and various other things. As you accelerate, your car’s engine is receiving a much higher dose of fuel than when at idle and conversely, when you let off the gas pedal, there is a sudden change in this fuel supply as a result of your foot letting off the pedal. When this happens, the job of the idle air control valve is to bring this deceleration down to a slow and smooth idle rather than suddenly cutting off the fuel supply causing the motor to die. When the idle air control valve is not working properly, this cause a disruption in this process resulting in the engine not being able to idle properly. I would recommend having a professional come to your location to diagnose and inspect your vehicle.

It will not start on starting fluid, it dies right away. Replaced fuel pump, fuel compressive regulator, and fuel filter
ANSWER : Hey there. If the motor will only start with the use of starting fluid, this suggests you may have a fuel supply problem such as faulty or dirty fuel injectors. If you have replaced the fuel pump and fuel pressure regulator, we can reasonably assume that you are getting the correct amount of fuel pressure through the system. You will need to check the voltage at each of the injectors to be sure they have the proper amount of power. You may also need to check them to be sure they are freely spraying the proper stream of fuel. If you would like to have this taken care of, a certified pro from YourMechanic can come to your car’s location to diagnose the starting issue and follow through with a fuel injector replacement (or any other repair) as needed.

Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
ANSWER : Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.

Engine won’t start and it’s a fuel related problem because I can spray starting fluid in the throttle body and it starts.
ANSWER : It sounds like you may have an air leak present in your EVAP system. When an air leak is present in the EVAP system, the MAP (Manifold Absolute Pressure) sensor will not be able to determine the air density, and the MAF sensor will not be able to determine the volume of air, entering the engine correctly. This will lead to an over fueling situation or an under fueling situation depending on the size of the air leak and engine operating speeds and load. This may eventually lead to catalytic converter problems as well as misfiring problems. As you may know, if the MAP sensor is not working properly, depending on the severity of the air leak (and the related adjustments the MAP sensor is making to try and compensate for this), this may in fact cause the motor not to start. I would recommend having an expert from Your Mechanic come to your location to diagnose and inspect your vehicle.

Car started shaking. Cleaned carb and air filter. Now it starts, runs, dies, or starts and dies.
ANSWER : Hello. The stalling issues you are having may by caused by a variety of issues. Typically these symptoms can be blamed on fuel, spark, or air. Fuel and spark being the most common systems to fail. Starting with the air filter and cleaning the carburetor were good steps to start. You need to take a better look at the spark system. The spark wires can be tested to make sure the plugs are receiving the voltage that they need to be. You can also test the fuel system by spraying some starter fluid into the air intake. If this helps the engine start and run better than before, then you know you have a fuel delivery issue. This may include the fuel pump, fuel filter, injectors, or a clogged fuel line. The shaking is due to the improper combustion happening in the engine. This will be corrected when the engine is running properly. More testing is the only way to know definitively what the issue is.
