I changed the starter cylinoid, starter, fuel pump, fuel filter and fuel pressure regulator and it still won't start. It will turn over and fire with starter fluid sprayed but it won't stay lit. I don't know what eles to change.

I have done a PSI check twice. Once before I started the work and once after I changed everything. Both times the guage read 0. I have spark. I checked it with and extra plug. Will the inertia switch shut off without an impact?

Where is the fuel pump relay located?

Ok, so I swaped the horn relay with the fuel pump relay and still nothing.

If it fires with starting fluid then you have two of the three components needed,air and spark.You have a fuel supply problem I would start at the fuel injection unit and work my way to the fuel pump (in tank).God Bless

Ok, If you have 35 psi of fuel at the rail, and you have spark, then you need to get or borrow a Noid Light, it plugs in the connector at a injector, while you crank the motor it should flash. If not then the PCM is not telling the injectors to fire. The first thing you should really do is check the codes in the PCM and see if there is any codes. You may have a bad PCM. Check the Inertia switch located at the passenger side kick panel, if the red button is up push it back down, this is only if you have no fuel psi, the fuel pump relay may be bad, Post back and tell more about fuel psi and spark.

After a couple hours (or when fuel system is bled down) turn key on without starting. You should hear the fuel pump run for 2 seconds to pressurize the lines. You can use a pressure gauge on the line to help.
If it doesn't, the fuel pump relay may be bad. Check for a pump shut-off switch, I'm not sure if Ford trucks have them.
Purchase a Chilton's for $18 to help. I THINK Ford has a pin on the ALDL that when shorted to 12Volts turns the pump on.

are the cylinders getting gas? Is the fuel pump on or did the wire on the battery come off? Is the emergency fuel cutoff tripped (located behind the brake pedal)? Are the fuses good? Is the gas line clogged? I have to be honest you didn't give a lot of details to work with it could be hundreds of things, i would trace the gas flow and see where its stopping or take it to a mechanic.

may have offered a nasty I.A.C.there is also anther area that runs on the fringe of the I.A.C. it has to do with the vacuum,also it would want to ok be the throttle position sensor.the position ever you're going replace i have not in any respect heard of sending the computer everywhere without the truck to envision the different sensors issues occurring.seek for a save that has the equipment to study.Ask if the have a Nemesis or Genesis,those type of retailers comprehend what you're speaking about.

There is a reset switch on them that I believe is located on the dash down by the heater on the passenger side kinda behind or right below the glovebox, push the button and it should start up

On the distributor there should be a gray box in fords these are also i believe the correct name is a voltage regulator you light want to take that and have it tested.
