It looks like your gas pump is out (or gas pipe is clogged).

Car sometimes quits while driving and hard to start after it does. No service engine light shows and nothing stored in computer codes.


Sounds like great advice if you are paying them by the hour.
You need spark, fuel to the injectors, and normal compression for the engine to run. One of the three is missing if it dies.
If it does not start right back up, someone should be able to narrow down the list of possible causes.
If it has spark to the plugs, it could be the fuel pump relay, or the pump. If it does not have spark, you need to find out why.

Briggs ans Stratton Quantum 5.5 HP still no spark after changing coil and plug


You are correct, you have a flywheel with magnets in, an electronic ignition unit which when the magnets pass the ignition unit core at speed energises and creates a spark via the plug, the earth wire simply takes the unit to ground and shuts off the spark, the unit you changed was it definetly an electronic unit or just a coil? if electronic and you are cranking the engine fast enough and have the plug well earted against the cylinder with the earth wire not connected it should spark.

My condenser fan is running backward


An abrupt cycle of power can cause a motor to run backwards. If you turn the power off again and wait 10 seconds or so (enough for blade to stop spinning) it should run the right way. Put the capacitor back the other way and try again.

I would suspect an electrical problem, either a faulty harness, or a harness that has brushed up against a hot, moving, or otherwise abrasive surface and grounded or shorted one or more of its conductors. Check by the exhaust manifolds, belts, pulleys for wires leaning against something they should not be leaning against.

When I go to start, it turns over but will not start. replaced fuel pump, but did not help.


Check your starter solenoid, (put key in run position and use a jumper wire to make contact to the two large terminals) if it starts replace the solenoid, located on the inner fender well. If there is no difference then replace the ignition module.

Why would a suzuki 4-wheeler not start. I have


Did you change the fuel filter? Is there a way to confirm that you're getting gasoline to the carburetor? If it fired once it should mean that you have spark to the plugs but there could also be a short in the kill switch circuitry that kills the ignition system. Pull a spark plug and put it in the spark plug wire socket, ground it against the motor and crank the engine and see if you're getting a good spark. Ensure that the air filter isn't dirty.

Raptor 660 idles but no throtle response


Turn off the gas and remove the water trap bowl at the bottom of the petcock, (gas valve). Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Get a set of the stock NGK spark plugs your bike came with. Check for spark on each cylinder before installing the plugs.

Now go to the idle and air screws on the outside of each of the carbs. IMPORTANT > > GENTLY turn both screws all the way in until they LIGHTLY seat. Now turn the screws EXACTLY one and one half turns outward.

SYNCHRONIZE THE CARBS
Remove the air filter and rubber fittings to allow you to see into the throat of both carbs. You may need a mirror to see inside. You need to be able to see the slides go up and down when you twist the throttle. Now turn the fitting where the cable goes into each carb such that there is just a bit of slack in the cable, 1/16" is plenty. Lock ONE of the cable adjusters down tight. All further adjustments will be made on the other carb.

With the motor turned off twist the throttle very slowly while looking at the slides. Both slides need to begin lifting at the exact same moment. If the slides don't raise at the exact same time then slowly twist the throttle until the locked adjuster slide just barely starts to move. Hold the throttle still and turn the adjuster on the other carb so that the slide on that carb just barely starts to move also. Now recheck the slide movement timing. Do this process until the slides on both carbs begin to raise at the EXACT same moment. Lock down the loose adjuster and re-check the slides.

BALANCE THE CARBS
Turn the throttle screw on the LEFT carb one half turn inward. Now start the engine and get it warmed up. With the engine running, remove the RIGHT spark plug wire. Adjust the idle speed on the left carb to the point where the engine just can't quite stay running and dies. Now put the loose spark plug wire back into place.

Now turn the throttle screw on the RIGHT carb one half turn inward. Restart and rev the engine. Next, remove the LEFT spark plug wire. Adjust the idle speed on the right carb to the point where the engine just can't quite stay running and dies. Now put the loose spark plug wire back into place.

Turn the idle screw on each carb EXACTLY ONE QUARTER turn outward and restart the engine. The engine will be probably be idling very fast. Adjust both the idle screws equally from this point to get to the desired idle speed. Congratulations, you have just synchronized and balanced your carbs.

PLEASE RATE THIS SOLUTION. Thanks!

Engine will not stay running


Hi

When the engine stops check the spark at the spark plug.Check compression(remove the spark plug and ground the plug wire on the engine,seal the plug hole with your thumb.Operate the starter.If the compression preasure blows your thumb off the hole,the compression is adequate for the engine to run.Now priming the engine(put some gas into the spark plug hole,back the spark plug and try to start the engine.Let me know. savumihai71 regards

** Help Starting **Yard Machine 21inches 139cc


amiseybold;

First check for spark. Remove the spark plug. Leave the spark wire connected. Hold the plug against the metal of the mower engine so you have a ground and can see the gap of the electrode where the spark jumps across. Have someone pull the starter cord and verify that you have a spark. Hold it by the threads of the plug so you don't get a little spark jolt yourself.

go to an auto parts store and get a can of starter spray (it's actually ether), Remove the lawnmower spark plug and spray a little ether in the plug hole. Put the plug back and tighten it and see if it starts.
It will probably start, run for 5 or 10 seconds and then die. Repeat this procedure once or twice again and eventually it will start to draw gas from the lawnmower tank.

A seasonal tip. when you put the mower up for the winter, **** the remaining gas out of the tank, start the engine and let it run until it uses up the gas in the carburetor. This will make iot much easier to start in the spring

Hope this helps Good Luck Loringh PS Please give me a rating
