Many solutions were suggested for this problem, but most of these were largely concerned with the movement of small green pieces of paper, which was odd because on the whole it wasn't the small green pieces of paper that were unhappy!

Page 1 Page 2. This voltage comes from the PCM power relay. Should have 10 to 12 Volts when cranking the engine. This power comes from the fuel pump relay. Front tank selected switch unplugged from its connector : Continuity should exist between pin 1 and pin 2.

Continuity should exist between pin 4 and pin 5. Rear tank selected switch unplugged from its connector : Continuity should exist between pin 3 and pin 2. Continuity should exist between pin 6 and pin 5. Do NOT follow this link or you will be banned from the site!Testing the fuel pump's pressure is one of the most accurate ways to verify that the fuel pump is good or bad.

Ford has made it super easy to attach a fuel pressure gauge to the fuel system to test the fuel pump since there's a Schrader valve on the fuel rail see image 1 of 2 in the image viewer. If you don't own a fuel pressure gauge, I have made some recommendations at the end of the article on which fuel pressure gauge set to buy and where to buy it.

When ready, ask your helper to crank the engine while you observe the fuel pressure tester's gauge. Your fuel pressure gauge will register one of the two following results: 1. The fuel pressure gauge will register 35 PSI, or 2. The fuel pressure gauge will register 0 PSI. This result usually means that the fuel pump is bad but not always. For example, you could have a blown fuel pump fuse, or a bad fuel pump relay or a fuel pump interrupt switch that has activated.

Taking into account the above conditions I've just mentioned and to make sure that the fuel pump is really the cause of this 0 PSI fuel pressure reading, you must verify that the fuel pump is getting power 12 Volts when the engine is cranking this is accomplished from underneath the vehicle, by tapping into the wire that feeds the fuel pump with power, with a multimeter. CASE 2: If the fuel pressure gauge registered 35 PSI : This fuel pressure gauge result let's you know that the fuel pump is working and delivering enough fuel to the fuel injectors.

The Schrader valve is always located on the fuel injector rail on the vehicles covered by this tutorial. Generally on the passenger side of the engine. The fuel pump inertia switch is tasked with the job of cutting power or ground to the fuel pump in case of an impact, which causes the engine to stall if it was running or for the engine to crank but not start due to a lack of fuel.

Although it's designed to activate during a severe impact cause by an automobile accident, sometimes it gets activated by less than severe impacts and this happens a lot. This means that it's always a good idea to check and reset the inertia switch whenever testing the fuel pump. On the majority of the vehicles covered by this tutorial, the inertia switch is located below the right side of the instrument panel, behind the trim panel.

Resetting the fuel pump inertia switch simply involves pushing down on the button located on top of the inertia switch till it bottoms out. You can find them here: Ford 4.

On that motor if I wanted to install a Fass pump and a bigger filter for the diesel side how do you bypass the factory filter and pump.

It would appear the way the factory filter and the injectors are connected this is not possible. I would like to see if anyone has a way to allow only diesel to be filtered in the diesel filter and VO in the VO filter.

With the current system the VO will always have to go through the diesel side. I want the fass pump to pump both the diesel and vo like on my cummins. Diagram of what it looks like now Ultimately I want something like this. The other questions is whether or not the factory mechanical fuel pump is sufficient for moving the grease from the back of the van to the motor?

I am planning on using HIH for the fuel so it should make it easy to move once it heats up. Any input would be appreciated. Re ford e 7. I started out by cutting the fuel return line and T-ing it into the fuel line so it loops rather than sending fuel back to the tank. Rather than a fuel valve and selector switch I have the second fuel system T into the existing fuel line.

Each fuel system has its own fuel pump on a switch so I can turn on diesel or WVO or both going up hills, which gets an extra miles or so out of a racor filter cartridge when its dark and rainy and I don't feel like changing filters.A word of caution about ether or starting fluids: a hot glow plug can ignite starting fluid before you have a chance to crank over the engine and will cause internal damage.

Jump to Diagnosis How the fuel injection system works These engines use what is called a hydraulic injection system. Fuel is delivered to the injection pump from the tank s by a mechanical lift pump. The injection pump contains a governor which contols the amount of fuel delivered to the injectors. The accelerator linkage basically changes the minimum governed engine speed RPM. If the engine speed decreases for a given throttle setting, the governor increases the amount of fuel to maintain the desired RPM.

The injection pump also contains a transfer pump which increases the fuel pressure inside the hydraulic head to PSI. Excess fuel passes through a bleed into the governer housing where it is used to lubricate and cool the mechanical portion of the injection pump before returning to the fuel tank.

The injection pump hydraulic head not only distributes the fuel to each injector, but also opens the injectors. It does this by pressurizing the fuel in the injector lines.

From the transfer pump the fuel is sent to a plunger-type intensifier pump which increases the fuel pressure further and sends it through the shaft and distributor rotor to each individual injector line, depending on shaft position. When the fuel pressure in the injectors gets above psi new injectors typically open at psiit overcomes the spring inside the injector and the valve pintel rises off its seat allowing the pressurized fuel to spray from the nozzel.

As the fuel is injected into the cylinder, the fuel pressure drops and the internal spring re-seates the pintel. Air inside the fuel lines compresses and this is what causes so many performance and no-start problems. Hydraulic pressure can't build, so the injector won't open. Changing the fuel filter When ever I replace a fuel filter on a diesel, I try to do it with the engine already warmed up to aid in starting and to ensure that oil is distributed throughout the engine.

If the Fuel filter header can be removed from the bracket, I do this because it reduces the amount of fuel spilled on the engine. Changine the filter is just like changing an oil filter--you lube the new gasket s with clean engine oil and hand-tighten only. Before installing the filter on the header, I refill it to make starting easier.

Use clean diesel fuel, but if you don't have any on hand, you can save the fuel dumped from the old filter in a clean container and strain it before putting it back into the new filter. Since the engine has been warmed up, it will start, but it is going to stall. Sometimes you can keep it running long enough by "feathering" the accelerator pedal to purge the air from the system.

But if it stalls, disable the glow plug system to keep from burning out the plugs by disconnecting the relay ignition wire, run a jumper from any positive battery source to the cold start solenoid and try to purge the air by cranking the engine.

Only allow the engine to crank for 30 seconds or starter damage can occur. Sometimes it may be necessary to loosen some injector lines and hook up a battery charger if excessive air has gotten into the system.Log In or Create Account Optional. Log Into My Account.
