F150 4.9 will not get fuel through the injectors will start on starting fluid..

You have wasted a lot of money buying stuff that is not needed.
Check the pulses from the crank shaft sensor.

Do you have spark and fuel pressure? Check the inertia switch? You might try a spray of starting fluid. If it tries to start you would know that the engine has spark, but the injectors could be working without fuel pressure and starting fluid would show you it is a fuel pressure problem if the engine fires with starting fluid.

If it dies immediately when you remove the starting fluid the issue has to be with fuel delivery.

EEEEeeeeeeeeerrrr .......NO PETROL!

As it cranks, is there white or black exhaust smoke ?? If yes, the fuel injectors have solid build up on the tips. Normally, a quart bottle of injector cleaner treats 20 gallons. Pour 5 to 7 quarts of fuel injector cleaner. With cold engine (been parked for at least an hour or overnight), while cranking engine, have 2nd person spray starting fluid into air filter. DO NOT PRESS ON GAS PEDAL !!! Let the starting fluid do its job of starting the car. Starting fluid is highly combustible, so its important you don't give any gas while its cranking and 2nd person is spraying into air filter. When engine starts, stop spraying starting fluid and give a little gas. If engine begins to die, immediately spray a little starting fluid again. When engine begins to run, let it run a few minutes to let fuel injector cleaner to do its job (loosen solid carbon build up on tips of fuel injectors).

if I'm reading this right...
... the engine starts and dies within a few seconds.
... you jumpered the fuel pump test connector and it will keep running.
... you smell fuel after trying to re-start when it dies.

Disconnect the plug to the cold start injector. Even if you have an issue with the engine running then dying after a few seconds after doing this, if you don't smell fuel after disconnecting the cold start injector and try to restart it, the cold start time injector time switch may be failing.

Buy a can of starting fluid and have someone start the engine then spray short bursts of the fluid around all the intake fittings. If spraying the fluid in any particular area keeps the engine running, I'd start looking for leaks around that area.


It does sound like an AFM or COR issue considering it dies after a few seconds, but the fuel smell when trying to restart the engine may be a separate issue that needs corrected / isolated first.it will keep running.

replace your injectors. your vehicle is getting the fuel to start from the starter fluid. however the injectors arent giving it the gas that it needs to stay cranked

Disconnect the wiring plugs from the injectors, Then remove the fuel rail (which is attached to injectors). Then remove injectors from the fuel rail. Don`t forget to change the "O-rings", (little rubber things on the end of each injectors). Otherwise there`s a possibility of fuel leak.
Also I suggest trying to clean the faulty injector at first, It might be ok, just dirty inside.
How to clean: Use injector cleaning fluid on the end of the head of the injector. Attach minus and plus to the contacts of the injector to battery of the car or any other energy source, and start pulling the negative wire on the battery on and off. You should hear clicking sound in the injector. Use the fluid and this "technique" for couple minutes or more, until the injector starts spitting the cleaning fluid evenly, not rarely. If still the injector doesn`t spit the fluid, you might need to change it.


Hope this helps, sorry for my english. I`m a lithuanian

Have you tried any starting fluid? Do you have Spark on all the spark plugs? Whay was it parked adn did it run then?

if it runs on starting fluid its a fuel problem.. check fuel pressure even if its a couple of pounds off, the vehicle will not run. but using starting fluid may give you the extra poundage you need to make it run . also check vacuum hose at pressure regulator on fuel rail
