Not getting fuel
I have a 1986 F150 4x4 - 302, I have never had a problem with this truck starting. It is fuel injected. Everyone said I needed a new fuel pump. I replaced the fuel pump in the gas tank, and still she won't start. The truck acts like it is going to start, but it won't. I'm lost! I am doing all the work myself (I'm a girl) so if you could please answer me in terms I could understand, I would love you all forever.

HI!.... JEN : Have you checked to make sure your fuel filter is'nt plugged up? When was the last time you changed the fuel filter? Hope this helps you out.

I had a 90 Bronco 351 EFI, about 3 years ago the fuel pressure regulator failed. It was causing the fuel rail to be over-pressured and forcing fuel through the injectors, even when they were closed. While I was talking to the tech, he mentioned that the regulators also cause an under-pressure condition, not supplying enough fuel to run, but just enough to fire occasionally.
You can check to see if your fuel rail has pressure by turning the ignition to run. Locate on the top of the engine, drivers side fuel rail, towards the front you will see a schrader valve (looks like a valve stem on a tire) with a cap on it. Remove the cap, take a small screwdriver with a rag rapped around it (to catch fuel) and depress the center pin in the valve. Be very, very careful, fuel is nothing to mess with. (If you happen to know someone who has a fuel pressure gauge to install on the valve, that would be the best way to do it) If the fuel does not "spray" out, you have no pressure and most likely (since you've already replaced the pump) need to replace the regulator.
The regulator is located on that same side of the motor, on the fuel rail almost all the way to the rear of the motor. It is round, about 4 inches across, sort of a gold color, and has a vacuum hose connected at one end.
To replace the regulator you will need to make sure all the pressure is out of the fuel lines. Disconnect the fuel pump electrical connector, remove the gas cap, and crank on the engine for about 10 seconds. Disconnect the Neg. (-) battery terminal. Remove the vacuum line from the regulator, and take out the 3 screws. Remove the regulator, there will also be a gasket and an O-ring. Make sure you get a new gasket and you will also likely need a new O-ring. Replace everything in the opposite order.
After all the steps are complete, turn the key on and off several times without starting the engine, and check for leaks.
I hope this helps you out, good luck.

Hi
Can you smell gas when you try to start it? Do you hear a buzz under the truck when you turn the key to where the heater fan runs? It will only buzz a few seconds each time you turn on the key. I had an 85 do that when the timing chain jumped a tooth. If you can't smell gas or hear a buzz, it might be an easy fix.
