My Jeep is having EVAP Issues

ANSWER : Hello Melissa, thank you for writing in. We can absolutely help you replace the EVAP canister or other malfunctioning parts in the system. If there is a vacuum leak in the system, you will need to locate it. An EVAP leak will cause the symptoms you are describing, and they will worsen as the condition of the canister leak worsens. Now when it comes to the fuel pump stopping randomly while filling, it too can be attributed to the EVAP system. The pump’s nozzle has a small hole that pulls in air as the tank fills. Once that hole pulls in fuel rather then air, the pump knows the tanks is full, and stops the flow. However, the fumes inside of the tank which are regulated partially by the EVAP system can build up and now allow the fuel to flow down into the tank. When the tank filler neck backs up, the pump stops. For more help resolving the issue, contact our service department to schedule an appointment.

ANSWER : Hi there. Typically when you hear a grinding noise when you move forward or in reverse it’s usually an indication of a gear fault either in the transmission or another driveline component. If this occurs only when in reverse, it’s likely a damaged reverse gear. It is also possible that it’s a hydraulic fluid issue not supplying enough lubrication or pressure inside the lines to fully open the gear. I would recommend having a professional mechanic come to your location and complete a car is hard to shift inspection, so they can diagnose the source of your issue and recommend repairs that should resolve this problem.

ANSWER : As you may know, the speed sensorslocated on the input and output shafts of the transmission relay information to the transmission control module which controls when the vehicle shifts based upon shift points. When these sensors are relaying incorrect information to the control module, this can produce the symptoms you describe. I would recommend having a professional from YourMechanic come to your location to properly diagnose your Jeep’s shifting issues and make repairs.

ANSWER : Hi there. If the vehicle overheated, and you noticed a lot of coolant on the ground, it’s quite possible that either the radiator broke, a coolant hose broke or the radiator cap was damaged. When this happens, a lot of coolant spills on your hot motor (which is the odor you are smelling). This can also cause damage to critical electrical parts that help the engine start and run. It’s probably a good idea to have a professional mechanic come to your location and complete a car is hard to start inspection, so they can determine what is damaged and needs to be repaired to resolve your problems. Without knowing what is damaged, it’s hard to provide an estimate for repairs.

ANSWER : If the starter motor is turning the engine over at adequate RPM, then you definitely do not have a starter motor issue. Even if you had a bad alternator (and the alternator should absolutely be tested, certainly when you install a new battery because you want to be sure the charging function is working properly) that would not prevent the car from starting. So, if the starter is turning the engine over, but the motor won’t run, you have either a fault in the fuel or ignition systems, or the air induction system. To "quickly" determine if it is a fuel system problem, you can try introducing starter fluid into the intake while cranking and if the vehicle starts at that point that would be an indication that you have, at least, inadequate fuel delivery perhaps due to a fuel pump issue. The most efficient approach to getting this resolved is to just simply request a no start diagnostic and the responding certified mechanic will make quick work of this for you. At the conclusion of the diagnostic he will let you know of the fault and the cost to repair. Please let us know how we can best assist you to get your vehicle running properly.

ANSWER : Hi there. I would believe, if the fuel tank inner liner was the issue, the stalling would occur at any fuel level. The dealer should be able to identify, any revisions to the fuel tank part number. It may be, the fuel gauge sending unit is inaccurate and your fuel tank is actually nearer to empty than you might think.

Average MPG times the fuel tank capacity may help discern this possibility. Given the stalling only occurs with a fuel tank level half or below, rules out a possible IAC (idle air control) valve causing the engine stall. Assuming, the Check Engine Light is not coming on, leads me to believe the ECM (Engine Control Module) is not recognizing the fault.

To isolate the issue, I recommend having your vehicle’s stalling issue diagnosed and repaired by a certified technician, such as one from YourMechanic.

ANSWER : Hi – first task is to check for problem codes (Check Engine light) – these will be helpful. From your symptoms, and the sequence, I believe the engine lost oil suddenly (failed oil cooler line or front crank seal?), and air speed or the engine fan blew it all over the engine compartment. Engine shut down, which means you had no brake boost (pedal would be extremely hard to push). I would recommend an oil leak inspection 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.

ANSWER : Hi there – your symptoms suggest a fuel supply issue, quite likely a fuel pressure check valve or fuel pressure regulator issue. Either of these can allow fuel pressure in the injection system to leak down while the vehicle sits. This makes the fuel pump work harder when the vehicle is next started, taking longer to get fuel pressure up to specs. I recommend a hard starting 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.
