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, ...

I never have drained the gas out of mine,i have always exercised them at least twice a year once in the spring then once when the cold weather starts coming in the bowls on the carb are still clean,then top the oil off and gas too add some stabilizer and wait for the next outage so far so good,and they have always started when needed.

I don't know about the Probe in particular, but I know some cars have a crankshaft position sensor that tells the ECU that the engine is turning over, and they won't turn on the fuel pump if they aren't getting a signal from that sensor. I'd also recommend checking your relays. Since it was an intermittent fault I'd suspect relays before fuses, but fuses can ...

Total and complete snake oil. As @AllanOsborne said, there has been many conclusive tests done on these "theories". It's complete bunkum. Besides, driving the same route and achieving a negligible difference in economy - without accurately measuring throttle position, engine load, etc - is just going to leave you with a biased placebo effect. You would ...

STA-BIL advertises gasoline integrity for 24 months It seems you have exceeded the advertised lifetime of 24 months by 12. Action Items Drain all fuel from the gas tank, fuel lines and fuel pump Inspect inside of fuel tank for rust and/or varnish from evaporated fuel You may need to clean your fuel injectors, you may not. Clean various components with ...

Following up with the resolution: I was right about the diagnosis. The rubber hose joining the filler neck to the fuel tank was deteriorated and cracked. The same was true of the vapor return hose. I was wrong about the cost of repair. I was charged about $375 in labor and $335 in parts, for a total of $810 (USD). The main labor cost was for removing ...

I did a quick check on the schematic and it appears that the two circuits are completely separated from each other. I also noted that the fuel sender circuit number is 36 and the horn is 63. You might want to carefully review the schematic.

Replace the float as well. Sometimes depending upon what material it's made the float can be somewhat soaked with fuel changing the weight of it.

Could Hydrogen [gas] Be Used as a Fuel [for motor vehicles]? Technically - yes. Practically - no. Fran├žois Isaac de Rivaz ... invented a hydrogen-powered internal combustion engine with electric ignition and described it in a French patent published in 1807 - Wikipedia People continued to invent gas powered vehicles, in the second world war there ...

OK, so the problem was that, due to a faulty fuel gauge sender, I over filled the tank. And since the seal around the top of the 'hatch' had partially disintegrated, well this happened: When parked on an angle, fuel was just flowing from the top of the tank :/

Yes but it would be impractical for Internal combustion engines. Though hydrogen has a very high energy density per kg, producing it, compressing it and storing it just to lose 70% of it's potential energy as heat losses makes little sense. This is why most hydrogen vehicles use fuel cells. Their higher efficiency (up to 60%) combined with the high ...

Hydrogen has been used as a fuel in various experiments. The largest-scale experiment I'm aware of is the BMW Hydrogen 7, a 7-series V12 produced from 2005-2007. About 100 were built. This engine could be switched from gasoline to hydrogen. The difference in fuel consumption is largely due to the different energy density with gasoline (petrol) yielding ...

Hydrogen is an ideal gas to be used for combustion, as there are no harmful emissions byproducts if the combustion (combination of hydrogen and oxygen) is at the proper ratio. You just make pure water, which is fine. There are several vehicles and several vehicle companies which have explored the concept of pure hydrogen as a combustible fuel. The ...

You can use hydrogen gas, yes. The main problem is that it is not easy to make. Most hydrogen (about 95% of all hydrogen used today) is produced by partial oxidation of methane and coal gasification, with some from biomass gasification. A tiny amount is produced by electrolysis of water (but it uses a lot of power to do so) So, yes, you can use anything ...

Theory 1 From your wiring diagram the horn relay has only 3 contacts; 12v, horn, button. This layout dictates that the horn button should ground the horn relay and not send it 12v. This is because the horn relay does not have it's own ground. Sending the relay power may cause things to behave strangely. Theory 2 The sending unit is a very old style. ...

so after pulling and checking each injector and reading all i could about this kinda thing, i found a few brief reference about the vehicle going into a 'safe mode', well that made me curious, because it sounded like what i had going on. so i just decided to unhook the battery for a awhile then try it. well it was running even rougher at start up after that, ...

Needle and seat issue Your needle isn't hitting the seat in the float. check for physical obstruction of the floats always replace the needle and seat as a pair. They fit together. ensure your floats actually float and do not have any holes in them If you provide more information like the model of the bike we can provide a less generic answer perhaps. ...
