It lists eight specific parameters that should be monitored while cranking the engine. Does the oil stink like gas?! Weak or dead pumps will run and run and run because the pressure never reaches the right level. The form states 100 rpm minimum, but a real-world value is above 120 rpm. You need to take it to a shop that uses a code reader that will or the Ford Dealer. This article will focus on a common driveability complaint with the Ford 6.
All other sensors helped engine run smoother. To start from begininng i have duel tanks and there had been bad gas in the rear tank from previous owners, so i decided to go ahead n drop the tank to get it taken care of, it was to messed up to get done in one day so i put every things bck together dropped both tanks since under there wanted to check cond. How do you approach a familiar no-start or driveÂability problem? 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. Air inside the fuel lines compresses and this is what causes so many performance and no-start problems. It will start, run about 2 seconds, then dies.
Both of my low pressure fuel pumps have gone bad over the last 8 years , junk yard ones not a safe bet. Do you take time to understand the system first or do you dive right into the diagnostic process, hoping your experience wins out? If anyone can give any insight into what the problem may be, drop me an e-mail or post an answer here. Will your computer or ignition module work in test truck???

As a note, before this problem started, the fuel pumps would come on when the key was turned on, run a couple of seconds, shut off if you didn't start the truck. I also show the engine and the details of it, start it up and see how it sounds under acceleration.
The oil filter housing contains two critical valves: One is an oil change drain valve that opens when the oil filter is removed, allowing the oil to drain back into the pan; the other is an antidrainback valve that uses a one-way check valve to keep oil in the housing with the engine off and the filter installed. Oil pressure in excess of 70 psi between the pump and oil cooler is vented back to the oil pan. Check fuel quality, electric fuel pump pressure and fuel pump inlet restriction. I was having such kind of problems with my f250 88, An 5. The red vertical lines relate to the values below the graph.
It needs a minimum of 100 rpm and 8 volts while cranking. If you have no owners manual it is easy to find out. Shut off and wait 30 minutes. O-rings should never be reused under any circumstance. The photo above shows what can happen when preventive maintenance is neglected.
Only allow the engine to crank for 30 seconds or starter damage can occur. Ford diesel truck repair is a good opportunity. Now im pretty mechanically inclined but i can not figure out what the heck. If the batteries are down a bit, there won't be enough power to turn the engine over fast enough to start. My truck will sit for thee months, crank over twice and start. Put a fuel pressure gage on the rail; record , crank, start, and stall pressures.
The most successful driveability technicians do not rely on troubleshooting tips; they use a logical process based on how the system functions. In the past 10 years, Ford has offered four different platforms—7. Check the oil level and add as necessary to reach the full mark. I have cleaned the terminals and corrosion from ground cables. In order for the fuel injectors to operate, a minimum of 500 psi oil pressure is required for start-up. What else should I check? Before installing the filter on the header, I refill it to make starting easier. New fuel pump relay, no help.
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. Jump to How the fuel injection system works These engines use what is called a hydraulic injection system. The opportunity to repair diesel vehicles is on the rise, and if your shop is looking for additional revenue, diesel repair can be it. The Guide specifies 8 volts minimum for all three A, B and C , but above 9. Zero volts might indicate wiring or connector issues. The high-pressure oil pump is driven by the camshaft and produces the high-pressure oil needed to properly operate the fuel injectors. I take viewers on a close look through the interior and exterior of this truck while showing details, over viewing of features, and noting unique styling cues to the vehicle itself.
Why is the engine oil so critical? Keep in mind that one bad injector will not create a no-start, so if the oil-related systems test good, the likely cause is fuel-related. The benefit is providing an alternative oil flow path during high oil flow conditions. Apr 11, 2011 need more info crank speed voltage at crank speed engine light on or off any codes oil pressure gage at crank if you have accses to 5000psi gage mount to right side valve cover removed the icp sensor installed gage must get min 500psi 300rpm and min 10. If vehicle does not start, continue with other non-oil-related issues. The oil travels to the high-pressure reservoir, where approximately 1 quart of oil is stored.
