Note that resolving these codes could involve replacing all eight fuel injectors. Any fuel system failure will cause the DPF to fail prematurely. 2 pump fails as the result of contaminated fuel or clogged fuel filters, the failure is almost invariably catastrophic in the sense that not only the pump is destroyed, but also that the damaged pump almost always distributes metal wear particles throughout the high-pressure fuel system and into injectors- which destroys the injectors, as well. The purchase needs to come before you have a problem with the fuel pump. It is hard to measure as results also depend on idle speed, environmental conditions, and so on.
The most common cause of oil dilution is fuel that leaks past the shaft seals on the high-pressure fuel pump. Also, watch the weight of your cargo, supplies, equipment and the weight of the trailer. One of those bugs has been the fuel pump issue. As you know, the more power you need, the more fuel your 6. 6.7 powerstroke fuel system diagram for 85 chevy caprice 5 0. This is accomplished by a strategy Ford calls "Zero Fuel Calibration", and its function is to detect, and compensate for deviations in individual injector performance from design specifications. One person stated that a rough estimate would be around 1 gallon or a little more per hour. This vehicle died on the road and hadn't shown a sign of loss of power, fuel leaks, etc.. What I've done and noticed: 1. The worst-case scenario is about 9 mpg. Refer to TSB 11-10-10 * if these codes are present, and follow the repair steps exactly to avoid further damage to the fuel system.
7L has a factory range, the amount of mpg you get is all determined by you. Released cap and heard air/vacuum being released. These are rough estimates of course as not many people do this test to find out this result. You're Reading a Free Preview. 7L Ford Powerstroke. Crank the engine; if fuel flows from the valve, the valve is defective and is the cause of the low fuel pressure. Nonetheless, fuel quality is extremely important for the efficient operation of this fuel system and seeing that the quality of Australian diesel fuel leaves much to be desired, 6. I will give you 1/2 correct on that's it. Disconnected fuel pressure sensor, still no start. If the two values differ by more than 50%, the ECU initiates a further strategy that is designed to adapt the injectors' duty cycle until the observed crankshaft speed matches the expected crankshaft speed, which brings us to-. 2013 6.7 Crank-No Start Issue. As a practical matter though, since the high voltages and pressures the injectors have to cope with generate a lot of heat, the injectors are cooled by a calibrated amount of fuel that flows through the body of each injector. It is possible to get between 9 and 30 mpg depending on your driving habits, terrain, and tow load.

In other words, after reading these results, your fuel consumption at idle will vary. Fuel system schematic diagram. Although it is true that Ford's Powerstroke family of engines has a legion of fans, it would also be true to say that diesel technicians the world over are not overly fond of this series of engines, mainly because they are notoriously difficult to work on. If you watch your towing weight and your cargo and passenger weight, then you should get fairly good results. 4-liter engines which is why they stopped contracting the construction of their diesel motors out to other companies. Hard-, or no start conditions. Two days ago it did the "running out of gas" imitation but if i held the pedal down it would have rough running high rpms but would only go about 20 mph. This switch is normally closed, and only opens when the supply pressure reaches 53 psi; if the fuel supply pressure does not reach 53 psi and the pressure switch remains closed for longer than 60 seconds the ECU illuminates a "Low Fuel Pressure" warning. Also, make sure to not be a heavy-footed driver as that will cut your distance down quite a ways.
All results reported here will be per the owners who have stated their results. Had to change filter and ran great again, then evidently had momentary probs with fuel guage and ran out of fuel( although guage said 1/4, until i had turned the switch off and then tried to crank then it said OUT). However, you may visit "Cookie Settings" to provide a controlled consent. The amount of mpg you will get when using the vehicle with this engine under the hood is up to you. I've read through other posts and still can't reach a fix. Misfires or random engine stalls can occur sporadically, or be permanent, depending on the exact nature of the problem. If an injector is at fault, the idling quality will change as each injector is disabled, but the idle quality will not change when the defective injector is disabled. If this is the case but the engine will still not start, extract all fault codes (including pending codes) stored in all control modules, and resolve codes found in the order in which they were stored. Other owners have said that the fuel used when idling should be lower than 1 gallon and place it at about 1/2 a gallon per hour. The average mpg that 6.

Turbocharger||single with two compressor wheels on the compression side of operations|. 2 mpg, and the next leg after 500 miles, he was getting 22 mpg.
I'm going to tap into the output of the secondary filter and see actual pressure. 7L Powerstroke engine is reliable, durable, and economical to own and operate. When you are towing a heavy travel trailer or 5th wheel you want a lot of power under the hood of your tow vehicle. 7L engines stem from faulty, defective, or malfunctioning fuel injectors, so let us start this section with a brief description of the-. If it were a pump wouldn't i have had warning signs?
You do not have to replace the entire engine fuel return harness which is expensive not to mention being a major pain to install. Noticed no rust nor metal on regulator valve on rear of left side rail. If filters are clogged, DTC codes P1291 and/or P1292 are likely present, both of which refer to short circuits in one or more injectors caused by contaminated fuel. Take the results with a grain of salt and not as a result you will get. If they did they had their reasons for doing so.
Note that engine knock caused by contaminants entering and damaging injectors is relatively common. 7L engines use a fuel conditioning module that is mounted on the engine to draw fuel from the tank with an electrically controlled pump. In severe cases, more than a litre of fuel can seep into the oil between oil changes, which makes it critically important to advise customers to check engine oil levels at least once a week, if not daily.

All you need to do is cut the fuel return hose just behind where the broken fitting ends and push the hose onto the barbed fitting on the new fuel line connector.
5 mpg but he was towing almost 15, 000 pounds. About under the driver's seat. Separated water collects at the bottom of the fuel transfer pump, and the ECU triggers a WIF (Water in Fuel) warning when enough water has collected to be detected. The few pointers listed above should enable the average technician to diagnose most injector issues, but there are other serious issues on 6. 7L engines built from 2015 onwards are fitted with integrated fuel pressure and temperature sensors that supply input data to the ECU on fuel parameters such as fuel supply temperature and pressure. 7L Powerstroke engine are always very expensive to repair, it is incumbent upon us to be sure of our diagnoses when we prepare quotes and estimates on repair costs. 4L motor had a lot of trouble with the failure of this vital part and even with the upgraded CP4. Tools can be bought from official Ford sources; service information can be had via a subscription to third party vendors, while Ford-compliant diagnostic equipment can be obtained from Having said the above, let us start with a short description of the 6.
