?? depending on year ,,,it could have a lift fuel pump in the tank to prime it up for starting ,providing its a conventional injector pump which having a hand primer i would assume it has ,need more info really but do check the fuel lines on the top of the fuel tank as they could be perished so its sucking in air ...or the lift pump inside the injector pump has failed ,really need to see it to know the problem .

2001 Hyundai accent wouldn't start this morning after sitting two days prime and no codes kept screwing with it I primed and runs then only primes sometimes but still runs great miss chug


Hi Miss Chug:
I'd start by using some carb/injector cleaner and make sure that the fuel delivery system is working properly.
If this is a carb type engine, make sure the automatic choke is not sticking.

Engine crank but will not start, checked fuel pump and it's not priming up not even after sitting overnight


You didn't reset the fuel safety shut off,
It only opens in an accident

The red button just flops around when the switch is closed

You have to provides details for us to suggest something

Checking the fuel pump-HOW details,test results,scan tool data,
pressure gauge,hear it run?

Spark-check for that
Check injector pulse?
Checked fuses & links

Battery any good-always start there unless you have a flat tire

If you can tell us through the proper testing that the pump
check valve has failed & you loose fuel rail pressure when it
sits,then you already know the answer & what to do

How would a fuel pump build pressure (not prime,there is non
of that) if the pump is turned off over night or key off?

Car not getting any fuel


Check the Inertia switch which cuts off the power to the pump. Depending on the Model, the switch is either behind the front floor kick panels or on the side of the trunk.
The part has a reset button so no new parts are needed. Sometimes you can borrow a pressure tester from a major Autoparts place and test whether you have pressure at the test port on the injector rail. Remember to turn the Ignition key to on.
If your vehicle is around a 1984 vintage, the injectors were installed in a carburetor shell. You could splash a little gas around the injectors to prime the engine. But a little starting fluid would work for all types of injected engines.
Since the electric injectors depend on pressurized fuel from the pump, fuel flow through the fuel lines is not dependent on a Vacuum draw used in a Mechanical pump. Point is the pressure on an electric fuel system will be available within seconds of turning the key so running the engine will do little that the electric fuel pump has not already done.
You can have a pressure regulator and the diaphragm can rot.

My car has been sitting for 3 years and now I can't get it to start. Is there any way of checking if fuel is getting through the fuel injection? That is what it sounds like to me; that no fuel is getting...


when you first turn the key, don't start the car just turn it to on, you should be able to hear the fuel pump prime, if you really want you could pull the injector out and see if its spraying, they are pretty easy to pull out of the motor.

04 f250 6l diesel cranks but will not start when cold.


it seems that because it sit's for a while that perhaps it's losing it's prime. if ythis happens generally you will have to reprime the fuel system. in a diesel system you also have glow plugs to help ignite the fuel. check to make sure your glow plugs work, but i would start with whether you have proper prime in the fuel system.. please rate this
