Why is fuel tank fitted with a valve?
Depending on the year, make and model of the vehicle it could be a "roll-over" valve to prevent fuel from spilling out in the event the vehicle was to roll over or it could be a tank vent valve for the EVAP system. More info needed please.
Your 2000 VW Jetta VR6 is hard to start when it sits a few minutes after driving It starts fine when it sits over night Any idea what would cause this?
Bad coil packs failing under hi heat temps or failing check valve in the fuel pump allowing pressure to drop in fuel system and resulting in fuel boiling in the lines resulting in a no hot start condition. where is the check valve
Why did check engine light come on in 2000 suzuki esteem?
suzuki has a recall on the esteem for a fuel evap valve on the gas tank. if the valve is damaged by hitting the body of the car, then you'll get an engine light indicating a large evap system leak. the recall covers replacing the valve and putting a pad over it to keep it from happening again.
2000 Chevy Malibu almost turns over but will not start Could it be the fuel pump?
Have you checked to see if you hear the pump when you turn on the key? Also check to see if you have fuel pressure on the test valve located on the fuel rail.
Does the 95 lumina have anything in the way of being able to siphon the tank?
Yes, a check valve that prevents the fuel from flowing back out in the event of a roll over.
Why does your TTR 90 leak fuel out of the over flow all the time?
check your float level adjustment and condition of float. also the needle valve seat.
Your van just died while going down the road it turnes over but does not start?
you might want to check and see if your fuel pump is turning on. what you have to do is get under the van by the fuel tank and have someone turn the key you should hear a little noise in the tank. also check the fuel reset button. there is also a valve on the fuel rail the you can access to see if you are getting fuel to the engineit looks like the valve stem on the tires just press it in with something and see if fuel comes out don't stand in front of it i will shoot out if its in there.
1997 Pontiac sunfire 2.2 liter no spark no fuel turns over but wont start?
Without fuel and the lack of spark, you can crank the engine continuously for the next 5 years and it will never start. One needs to find out why there is no spark or fuel. Start with the fuel pump and check the fuse(s), and then check the operation of the fuel pump. Check the electrical system of the car - check fuses, check wiring.
What does SFI OHV mean?
sequential fuel injection , over head valve
Why does the service engine light reappear approximately 24 hours after replacing the purge valve?
The canister itself probably needs to be replaced. The canister can become loaded with fuel over time, causing excessive fuel vapors to be sucked into the fuel delivery system.
What would cause a 1993 Toyota Celica GT 5 speed with a 2.0 engine to keep turning over but not crank?
Short answer: Clogged fuel filter Bad distributer coil Bad egniter Bad fuel pump Or it could be the valve connected to the fuel rail/intake manifold which manages the air/fuel. It involves water lines that tell the cold start injector system whether the engine is warm or not. (Can't remember the name this early in the morning) If this valve is in need of cleaning, or has mal-functioned, it will not let the vehicle start or it will start, only to die immediately. A mechanic would start by seeing if there is spark to the spark plugs, then he would jump the check connector with the fuel line disconnected to check for fuel delivery to the rail. Remember: check spark FIRST, then fuel, for safety's sake. If you have spark to the plugs when the engine cranks, and you have fuel, then it would be time to check that valve. It is located under the manifold (where the butterfly valve is)where the big air hose connects from the filter box/air control unit. Hope this helps.... Aunt hi mate, i have a Toyota 2.0gt. try having a look at the timing belt. if this has gone your engine will turn over but not start. be sure not to turn it over too many times or u might nacker engine. hope this helps mate..
My 1991 tracker won't start When you first try to start it after it sets overnight it sputters then just cranks and won't start Are there any ideas as to what might be wrong?
I would check the fuel pump and fuel filter, and fuel pressure regulator(make sure regulator is connected to vacuum source). Check the fuel lines at the engine with a repair manual. Be carefull not to disconnect anything with out following safety precautions. Fuel is under pressure and will blow out at you if don't follow correct procedure. if there's a small valve that looks like a tire valve, you can carefully check for fuel there. place a rag over something that can push down center of valve, and see if gas comes out into rag. if not lines could be plugged or broken(check for leaks all the way back to gas tank. Fuel Filter might be plugged. If still no fuel at engine or in the lines, it could be very well the fuel pump.
