Hey guys i have been trying to turn on my car but when i turn the key and check out my gas filter...it seems as if there is no gas passing through. In addition to that, my car seems as if it is dying out (i know cause of gas) but also i believe there is no power and it is a new battery. Do any of you guys have an idea what might be going on? Thanks guys.
Unless you have an electric fuel pump, no gas is going to flow until the engine cranks over for a while. It sometimes takes several seconds of cranking to fill the fuel line and the float bowl of the carburetor.
You may have a bad fuel pump, or a clogged filter. Or, you may have bad gas. Does gas flow through the filter when the engine is cranking over?
If it is an off the shelf battery you may need to charge it up as the motor may not be turning over fast enough to pump the fuel or fire. Try jump starting and pouring a little bit of gas in the carb to get it to run and fuel pump should catch up at higher rpm then just cranking. If your still not getting fuel then change your fuel filter. If you suspect a fuel pump problem change your fuel pump and put a filter between the gas tank and pump and try it. If it runs consider getting the tank cleaned or replaced with new but for the time being the filter should help keep tank crud out of the new pump.
as to what i see happening now to my car, there is no gas passing through the gas filter, i even got a new gas filter but the same old thing is happening. The car starts to crank and there is no gas flowing throung so my car slowly starts to die out.
Also wouldn't hurt to disconnect fuel line between the gas tank & pump & run some compressed air through the line to make sure there is nothing blocking the line. If clear, sounds like a bad pump. If you replace the pump, use starting fluid to get the engine to fire, may have to do it a few times, but will get gas to the carb faster & save wear & tear on your starter.
it could be a pluged fuel screen on the pick up tube in the tank. or cracked and or pinched fuel line. make sure the rubber hoses back at the tank are good. this is what I do to prime the fuel line before I start an engine that has a fuel problem. take the fuel line off at the carb. have a freind hold it in a can. take the gas cap off, and wrap a rag around a blow nozzel of your air hose and put it in the filler neck of the gas tank. then slowly blow air in to the gas tank (be careful not to put to much air pressure in the tank)and have your freind watch to see if there is any fuel coming out of the fuel hose. if no fuel comes out then the line is pluged some where. if it is pluged some times you can blow air back through the fuel line from before the pump to the tank. you should hear air bubbles in the gas tank.(never blow back through the pump as there are check valves in the pump and it will be bad for the pump). also is there gas in the tank (just thought I would ask)I have also seen the pickup screen come off the pickup tube and not pickup any gas till it had half a tank or better.one last thing if it has been setting for awhile I have seen the neddle and seat stick closed and had to bang on top of the carb to unstick it. hope this helped and not confuse you.
I procured a vehicle quite cheaply once because of a blocked fuel pickup line in the fuel tank. They had rebuilt the carb, replaced the fuel pump and the rubber fuel lines before giving up. It was a truck with the tank behind the seat, so I was able to remove the fuel level sender and pickup tube fairly easily, where I discovered the pickup tube was solidly packed with dirt for about 1 1/2 feet. I was able to get the truck home by cutting the line off and keeping the tank full of gas. Symptoms: the truck would start and run for about 15 seconds before quiting each time and wouldn't restart unless I waited a couple minutes. Long enough for the gas to "filter" slowly through the packed dirt after the fuel pump built up a vacuum in the fuel line, and refill the fuel pump. That gas would get pumped to the carb and allow the truck to run. My handy tip for starting a car that has been sitting for a while or seems to be having fuel delivery problems is to put some gas in a small bottle and fill the carb fuel bowl up through the bowl vent tube. I find this works a lot better than pouring the gas down the carb throat, as it allows the engine to start and run for a while, sometimes long enough to get the fuel flowing properly through the lines and pump again. It also saves a lot of cranking and gets the engine running with a normal amount of fuel for idling, instead of washing down the cylinder walls. And I can usually get oil pressure pretty quick without jazzing the throttle to try and keep the engine running - bad thing to do with an engine that hasn't been run for a while.
