Check fuel pump fuse, if fuse is good, most likely a bad fuel pump vor clogged fuel filter. Without knowing the make and model hard to say where each is located. Fuel pump is most likely in gas tank unless its an older vehicle.
No gas, weak battery (battery may be new but is it charged?), crankshaft or camshaft sensor is bad, fuel pump bad, fuel pump relay or fuse is bad, haven't pushed clutch down far enough(rug caught underneath), fuel filter clogged, ignition coils bad. You need to give a hint as to what you have tried. Does it crank but not start/ Does it simply click(starter) and not crank/
more than likely a clogged fuel filter[hopefully] if not that lets try this before you do anything.turn your key to the 'on' position can you hear a slight hum coming from the fuel pump in the gas tank under the rear of your car. it may take 2 people. one to turn the key on and one to listen at the rear of the car.try this several times to see if you hear the hum. if you hear the hum,the fuel pumps working. and then you know it's most likely a clogged fuel filter.if no hum heard,go under your hood to the main engine fuse box[black box] take the cover off of it. on the underside of lid,look for fuel pump relay,replace that relay with new one.if it's a fuse,replace the fuse. if this does'nt repair your problem,the fuel pump has went bad and in need of replacement.the pump is located inside the gas tank. the gas tank will have to come down and out in order to replace the bad fuel pump.try these solutions to see if they help,if you need further assistance,please repost your question to fixya.com and thank you for choosing fixya.com wish you the very best of luck!
dont go replacing everything...thats gonna get expensive real quick...especially that fuel pump. yep...the pump is inside the tank. stand out side your truck,and turn the key over,but not enough to start it. you should haer a whirring sound lasting about 2-3 secs. come from the back of the truck. this is the fuel pump powering up. if you dont hear it...then the pump is bad. if you do hear it, have a friend turn the key while you look at the carb/injectors to see if fuel is spraying thruthem,if it isnt....then you have a clogged fuel filter. BUT...b4 you do any of this...check your fuel pump relay and fuse to make sure they are good. a 10 cent fuse beats a 200 dollar pump any day.
keep me posted!!
Then either the fuel pump has failed, fuel filter is clogged, fuel pump relay is bad, or the fuel pump fuse is blown. Sit in the car in a very quite area or with someone listening at the fuel fill area with the cap removed and turn on the ignition without starting the engine. The fuel pump should come on for a few seconds and then shut down. If it does not then check the fuse and the relay. If it comes on then you know the fuse and relay are good. Replace the fuel filter. If that does not help more than likely the fuel pump is bad and needs replacing. The pump can run and still not be pumping any fuel. A fuel pressure test will verify if the pump is for sure bad. You have an 11 year old vehicle so it would not be uncommon for the pump to go bad especially if the filter has been neglected. A partially clogged fuel filter will destroy an otherwise good fuel pump. You will have to remove the fuel tank in order to replace the fuel pump. Use a hand pump to remove as much fuel as possible from the tank as gasoline weighs around 8 lbs per gallon. The less weight the better. Good luck and Merry Christmas.
Crank position sensor bad? Are you sure the fuel pump is working? Might be the sending unit in the fuel pump that is bad. Clogged lines, clogged fuel injectors, clogged fuel filter, all things that could be checked.
