Not all Diesels are the same. My former car, a 1994 VW Passat 1.9 TDI had only one fuel pump in the engine bay. This pump was responsible for several things: bring fuel from the fuel tank raise the pressure to the injection pressure (approximately 600 bar) distribute pressured fuel to each injector in the correct order There was no electric pump to "...

I had a 2002 Santa Fe and we were smelling gas whenever we filled up. Tried a new gas cap, checked the lines, nothing. Eventually we checked the filler neck. On the 2002 there was a cover to 'protect' the filler neck in the wheel well, but dirt could fly up and catch inside the cover. When I removed it, I saw the area where the filler neck was packed with ...

You could check the sparkplugs for fault signs. Please make sure the insulator has a light brown coloring. I suspect you received the wrong types of spark plugs (heat range), producing glow ingnitions

another thing to check are the engine mounts. i wouldn't be surprised if sixteen year old american rubber had degraded enough to transmit more shaking to the chassis.

The only thing which higher octane gas will solve is pinging (knocking or pre-ignition). As an aside, just because the gas is a higher octane does not mean it's higher quality. Higher octane gas does not burn as easy as lower octane gas. At most gas stations, the higher octane will not be any better. This does, however, differ given different brands of ...

Probably bad gas level sensor, which is a floater device immerse in the fuel tank, with an arm with a contact that touches a coil type resistance. When the floater moves up and down the arm touches the resistance wire, modifying the voltage to the fuel gauge. If the contact between the arm and the resistance is not even, or the resistance itself is damaged, ...

I recently troubleshooted a very similar issue on a friend's Outlander. Different car but physics is physics. He was complaining of a similar rough idle and occasional stalling when the car would come to a stop. Turning the A/C on helped smooth out the idle. The dealership was tried cleaning the throttle body, which reduced the severity of the symptoms but ...

Diesel does damages rubber. Diesel fuel may cause stripping of certain types of rubber hose, gradually perforating the fuel hose. Thus, it is strongly advised to make sure if the fuel hose to be installed is rated for diesel. To clean a diesel spill, you first need to pour lots of warm water on the spill to instantly reduce the risk of rubber damage. Then ...

Nice engine you got there! While your issues do sound like a MAF problem (check the MAF readings via OBD!), some turbocharged Volvos are notorious for fuel pressure regulator issues. Basically the regulator diaphragm ruptures and fuel gets into the pressure regulation vacuum hose. Typically this causes poor starting (especially hot) because of an excessively ...

Have him change the fuel filter. These get dirty and need changing. Very easy and cheap if it's external. Some are inside the tank. A dirty filter can restrict fuel flow. If you have high miles this could be the problem

I use Marine 2 cycle outboard TCW3 rated oil at a rate of 1 oz per 5 gallons. It must be Marine TCW3 rated not just 2 cycle oil. Check out Sarge LS1 on Google. Many people do this with great results. Add it at every time you get gas. It works like Lucas fuel conditioner but much cheaper. 1 oz per 5 gallons 2 oz per 10 gallons and so on.

If I had to guess this sounds like a four cylinder engine, with one or even two cylinder's misfiring. Best guess is a problem with either a spark plug wires, or an ignition module. I'm looking at high resolution photos of your engine compartment and its not clear on what type of ignition system you have. Generally there are two types of systems. One has a ...

"Down" should always be "open", and you can find out where is "close" position. Probably right or left. So "Up" will be "reserve".

I agree with Arturs answer about high fuel pressure but I suspect a different root cause for the high pressure. In your car there is a fuel pressure sending unit. This little box is attached to the fuel line and monitors fuel pressure. It send a message to another device that controls the fuel pump. This second device a Fuel Pump Driver Module (FPDM) uses ...

I see 2 reasons. 1. Bent or damaged fuel line between a fuel pump and engine, 2. Previous driver might increase a fuel pressure hoping that it will inject more fuel and make a car more powerful. To kill an electric motor you need to overload it. If the tank is clean, there is only one way left how to overload it. You can ask in garage to check a ...

It sounds like you have a motorcycle with a carburetor with gravity fed fuel line. (i.e. Without a fuel pump of any sort). In those conditions I can see that there is a higher fuel pressure at the inlet to the carburetor when the fuel tank is full. It's possible that when the tank is low the pressure is barely enough to meet fuel demand. With that said, ...
