Re: My truck is not pumping the gas to the carberator
Thats a back fire!Its likely got something to do with the timing wether its ignition or an engine is another storyDisconnect fuel hose at the carb(or fit your own) and put into tin try to start and see what sort of pressure and volume of fuel ends up in the tin Should tell you if thats the problem.If fuel is ok then its time to check the carb to see that its working properly.Have no idea what you have or havnt replaced but plugs and leads are also a source of the fault you describe.Let me know how you go as the more clues you give for your problem the more likely people are to jump in and help(usualy)

fuel pump is in the tank & can be heard for 2 seconds when key is turned on. there is no reset but by listening at gas cap you can hear if pump runs or not. spray carberator cleaner in throtle body(carberator) to see if it helps with starting. there is a test port to check fuel pressure if you think its a fuel problem & carb cleaner helps it start
You don't have a carberator on it, it's fuel injected. Id try spraying carb cleaner in the throttle while you have someone turn it over. If it fires up for a few seconds then dies then you might have a fuel pump problem or fuel filter clogged. If it still doesnt fire up then check if you have spark, if no spark see if your crank sensor is good and if your coil is getting power. If your coil is not getting power you might have a crank sensor problem. Try this and let me know if it helps.
without starting the engine position the key to the on position. you can hear the fuel pump operationing for 4 to 6 seconds upon having the key on. if not heard running check the fuel pump fuse, the fuel pump relay, and the engines oil pressure switch. they all work the pump you see the engine oil pressure switch runs the pump untill the engine reaches normal pressure once the pressure is reached to the normal range the computer shuts that circuit off and turns the fuel pump relay on
It's hard to figure out whats going on with out any codes. Im thinking maybe the fuel pump. To check it after it stops and doe'snt start squirt some starting fluid into the carb and see if it wants to start. If it trys to start then it's a fuel problem.
Take off your gas cap and have someone stand there with thier ear at the hole, (no smoking), turn the key to on just before start and they should hear the fuel pump humming. if they dont then try to start. if it doesnt start turn key off and at that instant the pump should be heard again. What i think is happening is your pump is not energizing . Its supposed to energize when turning your key on and off. This can be caused by a bad fuel pump or pump relay switch. Hope this helps. please rate me
