Fuel dripping off of the bottom of the bell housing, starter, OR off of the entire transmission in general.Also check the fuel drain valve:--disconnect the drain line (slides off) and remove 4 bolts holding the valve on (torx screws). IF FUEL leak from top of the engine :--- It is likely in the fuel return system. This is a series of small hoses that run from injector to injector, then to a central return hose back to the tank. These are usually connected to the injector with a plastic fitting that has an o-ring inside.

In this case the O-Rings and injectors have to be checked and replaced.------------- The fuel filter heater located under The the fuel filter inside of the fuel filter housing. fuel pump is located on top of engine,behind fuel filter and in front of turbo .---------- The small o rings in fuel filter on bleed off valve can leak it will look as though it is leaking under turbo but is traveling down the valley of the motor.------------ You can also remove the fuel pump and check if its worn out/faulty/cracked causing the leak. First DE-pressurize the fuel pump system.For this Open the fuel filter and water separator drain valve with your hands. Lift the front of the vehicle using the jack and give proper support.Then disconnect the harness that runs to the fuel pump.Disconnect the retaining clip on the fuel line with your hands and remove the fuel line from the fuel pump.Disconnect the fuel delivery hose.Remove brake lines holding fuel pump.Then unbolt fuel pump securing bolt,Then check the fuel pump and its connecting parts condition and replace the faulty. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

I have a 1994 ford escort and it's not getting eoungh power I've change the battery, sparks plugs and the alternator don't know what else to do please help


Did you check the timing? If the timing is off there will be a reduction in performance and power will be greatly reduced. If the engine is "pinging" or "knocking" under heavy acceleration, your timing is advanced, and pre ignition is occurring (that's when the spark has ignited the fuel in the combustion chamber prematurely), resulting in a knocking sound. When the piston is compressing the air/fuel mixture within the combustion chamber, the spark plug produces a spark from current it receives from contacts closing in the distributor cap. (Where all the spark plug wires are plugged into) if that spark come BEFORE the piston finishes it up stroke or compression stroke, the piston is then being slowed down from the kinetic energy produced by the exploding fuel. Thats where we loose our power. Idealy, the spark should come AFTER the piston has rotated over the top of its stroke, It has reached its limit in compression and is on its way back down then the spark should ignite the compressed fuel, thus giving the piston an additional "shove" back down to start its "Power" stroke, once its reached the bottom of the power stroke (stroke #2 of 4) it is then carried back up for the "exhaust" stroke pushing the burnt fuel out of the combustion camber and into the exhaust manifold, one it has reached the top of that stroke it begins its journey back down to start stroke number 4, the Intake stroke. Drawing in air/fuel mixture to again be pushed back upward to compress the air/fuel, and repeat the process over and over again. Now that I have thoroughly bored you to tears, Yeah, check the engine timing, if its not the timing it may be a vacuum leak.

Ses doo 2013 grx limited 260 wont start Why


The internal combustion engine is quite simple. All you need for it to run is compression, fuel & a spark to ignite it. I'm not saying it'll do 40 MPH but it should start & run. If it doesn't then one of the 3 elements is missing.
You need the following - sounds stupid but it wont work if one of these is missing.
1. PETROL - fill the tank to be sure. If its a 4 stroke just petrol. If its a 2 stroke petrol & 2 stroke oil mixed or top up 2 stroke oil tank.
2. Fully charged BATTERY. Clean connectors on battery tops
3. a SPARK at spark plugs. Clean them while they are out. If no spark look for dodgy coils, plugs, HT leads, triggers.
Look for air leaks in fuel line - if bulb does not go hard you got an air leak. Does it smell of petrol? check for leaks in fuel line & around carbs, look for perished fuel line, loose clamps or if they are jubilee clips, they could be too tight, crushing the anti-syphon valves at the primer bulb. loosen them until squeezing the bulb scoots fuel out then re-tighten JUST enough to stop fuel leaking.
Does it turn over? - then battery ok & not seized
Does the choke operate? operate lever & confirm things turn properly on carbs.
Once its started you can fine tune it but it needs to start first!!

I have an oil leak at top of motor and car didn't make this whining noise at first I checked the power steering and its full could the whining come from the leaking issue


Does the whining volume increase when you turn the steering wheel back and forth? If so, your power steering pump is on its way out. The "oil leak at top of motor" is not very descriptive. Is the color of the oil the same as the color of the power steering fluid? If so, it is likely that leak is coming from your power steering pump. If not, I would need more information to determine the cause of the leak. What color is it? How much is leaking? Does it leak when the car isn't running, or only when it is running? Where exactly on top of the motor is it leaking? A hose? A seam in the engine?

2001 ford taurus, 3.0 vulcan motor. just rebuilt the whole motor, backfires out of the intake, seems to be out of firing order. i triple checked my work and can't find the problem. whistling sound of...


Back firing out of the intake is because the valves/cams are not set right. When you did the timing belt . did you set the crankshaft mark at top dead center of the compression stroke. If it's at the exhaust stroke this would cause backfiring and violent shaking.

Im 16, and ive never ridden a 2 stroke in my life and im thinking of getting a yz/sx 125 for trail riding. ive never been able to afford a modern 4 stroke so ive been riding a crf230 and a 1980 tt500 yam....


I would suggest a 250 2-stroke or a 4-stroke. Lots of power, lots of pull and the motor would likely last you for years. I've raced both the 125 and the 250 2-stroke at the pro-am level (A-class) and the difference in engine life is tremendous. I would re-ring a 125 every week (running 26:1), while with a 250 I could go for 2-3 months or more without doing the top end while running 32:1.

A YZ 125 will definately be a bit of maintenance - primarily because it has a single ring and the ring doesn't last long. A pro or semi-pro racer would re-ring every race (when the 2-stroke was popular) - some races I would re-ring in between motos. I know you won't be racing, but I would still imagine you would want to freshen up the top end at least every other month at the most. Granted - you can re-ring a 125 in about 45 minutes for a cost of about $18 if you know how and it costs a LOT more for a 4-stroke and is more of a job.

Other than the ring, the rest of the maintenance will be about the same between a 2-stroke and a 4-stroke. You'll still have to do your air filter every ride and your engine oil (tranny oil in a 2-stroke) every other ride. Tires, spokes, sprockets, clutches, chains, brakes - all pretty equal maintenance between the two. Lots of variables, of course.

The difference will be keeping the motor fresh and for that, the 4-stroke will beat the 125 2-stroke. Not the 250 2-stroke, though - these motors last as long or longer than the 4-stroke and are a LOT cheaper to maintain/rebuild.

This is MY experience and my opinion. Your mileage may vary.

Power brush will only operate on push stroke


If the motor runs, the circuit breaker is working. If it only works on the push stroke, you probably have burnt contacts where the handle and/or wands and/or power head connect. When you push, the contacts are pressed together; when you pull, they are separated and the motor loses power. The only solution is to replace the connector parts.

Oil Leak at exhaust flange


No major problem. The proper mix is 32 to 1 gas and oil. That equals 4 ounces of 2 stroke ENGINE oil to one gallon of gas. Do not use MOTOR oil in the gas. 10w40 motor oil is what goes in the gearbox. Tighten the exhaust flange.

A top ranking please ... Thanks BJS!
