I have a 97 Dodge Dakota that I replace the fuel

Find out if the engine is getting gas to it. Sometimes a plugged fuel filter or a problem with the fuel injectors can prevent the engine from getting any gasoline. To check this remove the air cleaner and smell inside the throttle body or air cleaner housing. If the engine is getting enough gas you should be able to sense a strong gasoline smell due to the amount of uncombusted fuel left inside the intake manifold.
Determine whether the spark plugs are firing. If there is plenty of gas but no spark, the engine will crank but not start. Unplug one of the spark plug wires and plug in a spark tester. Have a friend get in the car and crank the engine while you watch to see if the spark tester illuminates. You can usually purchase a spark tester at an auto parts store for about ten dollars.

Gas spits back if I pump too fast, and the check engine light is on --maybe a vent is clogged--Help!

GASOLINE in the air filter is a serious fuel injection be honest....I have never heard of such a problem...air goes through the filter into the cylinder where it mixes with have gas spit back into the air filter.......exhaust valve stuck? Maybe intake manifold is leaking? Gas from the tank goes straight into the cylinder via the fuel injection does it get into the air filter is really a problem. .

I have a 2003 Honda VTX 1800 fuel injected with a "no start problem" I am getting spark but no fuel and am not sure where to start checking. I can hold a gas soaked rag over air filter inlet and it will...

This means your injectors may not be getting any gas, a bad gasoline pump, or clogged filter most likely. First check your fuel level and then your filter, pull it out and make sure is not completely clogged, if it is, replace it. but before you install the new one, place the flow gasoline hose end ---> in a small container (protect eyes) and keep your distance and have someone turn the car switch on momentarily ( just the switch, not cranking!) to see if the pump is pushing the gas into your container, if you don't get any gas on the filter flow hose that means your pump is also burned. Dealing with gasoline problems can be very dangerous, if you are not mechanically guided, have a mechanic check it for you better. good luck!

2003 Nissan Altima won't start?

A car needs 3 things to start. Air, fuel, and spark. Check that it can get air by removing the air cleaner and inspecting it. Leave the air cleaner off for now. Try a squirt of starting fluid into the carburetor (not a lot mind you, just a quick squirt). Be prepared to quench a flame if the engine backfires through the carburetor (have a wet towel handy). Crank the engine. If it fires, you have spark. If it does not fire, you have ignition problems. If it fires and stalls out quickly, you have fuel problems.
For fuel problems: Be sure you have gas! (I know it is obvious, but check the tank!). If the car has not been used for awhile, the gas may have gummed up the carburetor. While it is possible for the weekend mechanic to take a carburetor apart and clean it, it is probably best left to a professional mechanic. Verify that you are getting gas to the carburetor by detaching the rubber gasoline hose at the carburetor. Most cars today have electric fuel pumps, so turning on the ignition should result in a stream of fuel from the gasoline hose. If not, crank the engine and see if a mechanical fuel pump moves the gas. If you get no gas, find out why or your car will never start. If you get gas, the carb is probably gummed up. It is best to conduct this last test into a mason jar to catch the gas, and it is best to postpone the cigarette break until after the test is complete.
If you suspect the ignition, pull a spark plug. It should look clean and whitish to light coffee color. If it is filled with carbon and oil, you have other engine problems. You can look for an ignition spark by laying the plug case against the engine while it is attached to the distributor wire. Crank the engine and you should see a spark jump the gap at the spark plug tip. This spark is often small and hard to see in sunlight. Do not perform the spark plug test in the temporal vicinity of the fuel test. A hot spark with gasoline nearby is dangerous.

A car that turns over means that at least the battery is good. Try next to insure it has air, gas, and spark.

Hello, Volut cracked overnight and leaked for several hours, drainig the pool down well over 1 foot. Next day, replaced volute, but now polaris is not functioning. Water is being pumped into the...

With a new volute the most likely causes for low pump flow is a restricted return line, a restricted suction line(or air leak), or there is something wrong with the impeller in that order. There is a filter screen in the return line that can cause the return line to be restricted if it is plugged. It is either in the wall fitting or in the tubing system close to the wall fitting. If it is dirty it means that debris is getting into the system. Typically an early indication that a grid in a DE filter has a leak in it is a plugged cleaner filter screen. The speed of the motor could be causing the problem but this is rare without causing an over current condition in the motor causing it to shut off. My suggestion is first check the return filter screen. If it is dirty then clean it out. Before connecting the return hose start the pump and check the flow by reaching down and manually putting your hand over the water stream coming out of the wall fitting. Turn off the pump and connect the cleaner hose without the filter screen installed. Disconnect the hose from the cleaner and hold the end of the hose while someone turns on the pump. Water should come out of the hose at a high rate. Next install the filter screen and the flow coming out of the hose should be about the same. Now try connecting it to the cleaner. I hope this helps.

Unable to crank? Do you mean unable to start?

If you leave gasoline inside tank over long period of time, that will 'gum-up' and ruin carburetor.
To prevent problem, put additive in gasoline or empty gas from tank:: under gas tank should be a hex bolt that holds up gas filter > loosen bolt and drain gas.

Starting the engine:
Take off air filter and spray WD-40 directly into carburetor.
Start engine, engine should fire on the WD-40 accelerant.
If engine fires but does not keep running, try spraying WD-40 into carburetor continuously to see if you can keep engine going.
If engine stops each time after it no longer gets WD-40, then carburetor is bad or gasoline not getting to carburetor or gasoline is bad.
Try fresh gasoline.
Do not turn small engine on side or upside down or oil will get into carburetor.

Check gas supply: Go to gas filter under gas tank. Pull loose rubber hose that connects to carburetor and see if gas comes out rubber hose.
If gas is flowing to carburetor, then carburetor is gummed up.
Small engine repair might suggest 'gum out' or have other suggestions ... but you may need a new carburetor

If engine will not fire on WD-40
If engine will not fire on WD-40 at all, then spark coil may be bad or exhaust port is clogged
Check screen that covers exhaust >> is it covered with carbon and dirt or can air pass through it easily?
Check spark
Remove spark plug
Put spark wire back on spark plug
Hold spark plug by rubber spark cap so hands don't touch metal part of spark plug
Touch spark plug threads against hole where spark plug was removed >>> metal to metal so it conducts electricity
Pull start cord and look for sparking between spark plug threads and metal of engine (don't look at the spark gap ... look where metal meets metal
If you have no spark, the spark coil is bad >> time for estimate from small engine repair shop or get your part number and order replacement

It's not flooded is it? Try holding the gas pedal to the floor while trying to start it. If that don't work try taking an oil can and put some gasoline in it. Now try to squirt some gas into the intake somehow, there should be a hose that goes from the air cleaner tube the valve cover. Pull that hose off and squit some gas into the air cleaner tube. Will it fire like that? Are you getting a check engine light? It's possible the cam position sensor is bad you will still have spark but, not at the right time. Good luck.

If circulation is better when you pull the cleaner from the water the problem may be in your hose's. With the pump running pull the hose's from the water one at a time to see if you hear air leaking into the hose's and then replace the bad ones. Hope this helps, good luck
