If fuel is being injected into the combustion chamber, there will be a nice cloud of atomized fuel being blown out into the air. What is the outside temperature while you experience this hard start? Stop and think about engine compression. The second fuel filter is located on the engine, and incorporates the water separater. They have been known to crack and in that fuel pressure is much higher then coolant pressure it mixes that way and not the other. Glow plug relay and air intake heater relay are mounted on top of the motor.
Replaced fuel filter and no difference. Again, spray diesel in intake to test for fuel issue, manually control glow time to see if that helps, Check batteries to make sure you are turning over fast enough. You may need to have the truck diagnosed so you know what direction to go in. Change the fuel filter to ensure you are getting adequate fuel pressure. The o-rings fail from heat and time and also sometimes from extended drain intervals which takes it's toll. I turn the key to on position to where the fuel pumps cut on and they run for like 30 minutes to an hour and then they'll shut off and my truck will crank fine.
The red arrow is the connection to the battery. By - May 23, 2016 Contributors: Bryan Wood This article applies to the Ford F250 and F350 diesel engine 1994-2003. With the advent of the electronic diesel fuel injection system, a scan tool and scan data will be your friend. I know there's a lot of expertise here, so I hope you can help. Instead, the engine can't run without fuel pressure so it stalls. There have been cases where that magnet has cracked and poor signals get generated.
He says it runs perfect otherwise. Jun 19, 2014 You may want to surf around on some of the powerstroke forums for detailed answers, but I know the powerstrokes use oil pressure to control the injectors so you may have some problems with the high pressure oil pump. Gas powered engines and diesel powered engines ignite differently. The technician might need to start with an inspection of the batteries, which will include a load test of the batteries, some voltage drop testing of the negative and positive sides of the starter circuits and maybe a current draw test on the starter. One reason I suggest some scan tool testing is because there are a lot of parts that need to be removed to gain access to the troublesome part, and most of these parts must be installed before the engine can be started. If the starter has power and bench tests good, proceed to Step 4.
To access the switch, open the passenger door and take off the access panel. Guessing at the fuel pump is putting the cart in front of the horse. Answer I helped my mechanic change one on my 1999 Tahoe and it was not easy. Tighten it when you get fuel. Cold starts are aided by the fact that the cold oil does not leak past the failed o-rings. I will run mine for 25 seconds when I am priming the fuel system, and then I will give at least 10 minutes before I crank again.
Maybe its a bad glow plug controller? Your computer regulates the advance, however, have the distributor … checked. My tank is full as well. If low compression it would be very hard to start when cold. Ford recommends replacing the spark plugs every 100,000 miles. After we swapped them out, still no start. But if it doesn't start, it is just a strong truck you can't use.
My truck began to start with some difficulty a year ago, it would turn over and over and finally start. If the engine has the proper compression, the proper cranking speed and the proper amount of fuel injected at the proper time, the engine will start. Here is where things start getting a little complicated. You have 2 of this type r … elay under the long cover just below the windshield on the firewall. Step 4 — Check the glow plugs They could not be functioning. If all these tests pass, then check for something binding inside of the starter or the engine.
The best thing to do is go to Autozone and get a manual for the truck and follow the step by step instructions on getting to the fuel regulator. On the late model diesel engine, accessing a point to get the compression can be a time consuming task and there are easier ways. There are various parts that could be responsible for a diesel truck not starting, from electrical components to fuel issues, but most non-starting issues can be fixed without a professional mechanic. If there is excessive corrosion on the terminals, clean it off with a wire brush and try to start your truck again. To access it, you'll need to remove the plastic cover that is held on with two bolts.
