Question about 2007 Ford E-350 Super Duty Length XLT

1 Answer

Own a 2001 E-350 7.3l engine cranks, doesn't start. Thinking it might be glowplug related (fuel fumes come out of the exhaust after a number of attempts... So it is getting fuel) What can I test myself, (where do I find the bits to test... It's really tight in there!)

Try plugging in the block heater and see if that helps with the starting. Haynes has an excellent Diesel Engine Repair Manual, part #10330 that will help you find and fix the problem. It includes photos and tips as well as upgrades. It also gives you test readings to look for and how to test as well. It covers the 6.6 and 7.3 as well as GM 6.2 and 6.5. Hope this helps.

I have a 2005 Ford 6.0 diesel. Sometimes cranks but won't start, other times it cranks and starts. Can pull it off, and it will start and run fine. What could be the problem?

Since some of your starting problem can be when you need the glowplug timer to work. There is a power relay which supplies power to the glowplug timer. After the engine warms up, the timer has little to do with starting.

You could also need new, clean glowplugs. When you do need the glowplugs to work, they can only get power for a fraction of the time that the timer works. If the glowplugs are worn or dirty, the glowplugs may not heat sufficiently to ignite the diesel fuel.

1995 freightliner. Will crank but won't start. How do I fix it?

First, check your fuel to make sure there's no water in it. Next, find the fuel system bleed port located near the fuel injector. loosen the bleed port bolt and have someone crank the engine. When fuel flows out of the bleed port in a steady stream (no bubbles) close the bleed port and start the engine. If it will not start, loosen one of the injectors and crank the engine to see if the fuel injector has fuel and if it is pumping fuel. You may have to loosen each of the injectors one at a time to get fuel to all of the injectors.

I have a Hyundai Trajet 2002 Gasoline. I have a problem with keeping the engine alive.

The engine is running very rich that is why the exhaust is emitting black smoke. The engine needs a tune up so the air fuel mixture is correct.

My 1999 f250 superduty 7.3 starts right up when cold but hard to start after it is warm and surges while driving at 55 mph. it does have a 6 speed ******.

There may be more than 1 problem. The Timer for the Glowplugs adjusts itself for the temperature of the engine and surrounding air temperature. It is suppose to keep the timer going longer for a cold engine than a warm one. But it does need to heat the Glowplugs to atomize the fuel, then compression takes over.

If the Glowplugs have not been inspected lately, it would be a good time to do it. To test, use a jumper cable with care not to damage the threads of the Glowplug. Usually clamp one end of the jumper on the base of the Glowplug and briefly touch the top where the wiring plugs in.

The Glowplug can melt, but you want to see it glow in a short period of time and uniformily with all 8. Any that stay dark are bad, subpar will take longer than you have and will not fully atomize the fuel before they lose power from the timer.

Another problem can be the gating in the Turbo. There should be clean passages for the valving to seal when the Turbo closes. If the Turbo does not close, the exhaust compression may leak into the cylinder too early before a fuel charge is atomized. Since the Glowplugs are barely on for a hot engine, it will complicate starting.

Since your engine starts great when cold, fuel line integrity and the fuel system should not be a problem. Surging at 55mph is probably due to the Turbo.

Check your Vacuum levels at a convenient tap and see if the Vacuum bleeds off quickly or holds pressure for awhile.

Please rate my info and I hope I have been helpful.

Gas order inside vehicle - could this be caused from the fuel pressure regulator?

If it is a gasoline ( raw fuel, unburned) smell, it could be caused by a number of fuel line related problems and leaks including the fuel pressure regulator. If it is an exhaust smell, check for an exhaust leak in or near the engine compartment.
There should be a cowling hood seal at the rear of the hood that is supposed to keep those fumes out of the passanger compartment.
Good luck.

Hard starting Hard starting Ford diesel 7.3 Power stoke 2000 Cranking over just doesn't seem to fire, but runs fine once running.

Hello, there are several things as likely to cause this problem, either spark or fuel.

The glowplugs are needed to make a Cold engine start. You can take a testlight to the glowplug wire of several cylinders and it should light when the engine is put to the Run position. The glowplugs get their power from a Coldstart Timer and it may have an additional relay.

The Coldstart Timer is the part which clicks and makes the lights dim when it is cycling. It also controls the dash indicator and makes the dash light work when the glowplugs are ready. The timer changes the amount of time it cycles according to outside and engine temperature. If you have noticed the "Ready" light vary its timing, the timer is working.

Say you have no spark at the glowplug wire, work backwards to the Coldstart timer and see if it is getting power. Power in, none out, bad timer. No power in, work backwards for a Relay or fuse.

Now if you have power at the glowplug, remove several and test them with Battery jumper cables. Put the NEG on the base and touch the POS to the stem. You can melt them if you overdo it. The longer it takes for the glowplug to glow, the worse it is. Once you find a good glower all tests are relative to the good one.

Fuel problem. If the glowplugs test out, check the fuel. Long start times can mean the fuel drained back to the tank and has to be pulled all the way up front. You can unscrew your fuel filter and see if it is topped off or empty. Then you need to test the lines from the fuel filter back.

It is also possible an internal Solenoid in the Injector pump is sticking. A light tap before starting can indicate this problem if it starts better after tapping the pump.

Thats about it. I hope you find my Solution useful.

I have a 2006 super duty f250 diesal.It cranks,but will not start.What do I need to do? I replaced both batteries with new ones.

Get a voltmeter or Test light and take off one of the Glowplug wires. The Glowplug is similar to a sparkplug and is not connected to the Fuel rail. You want to see if the Glowplug wire is getting power. The wire should have at least intermittent power, full power for a initial Cold start. This power lasts under 2 minutes.

Diesels need a Hot Glowplug to start the engine. All of the Glowplugs are connected to a timer box. The timer box is also Temperature controlled to stay on longer in the coldest weather. You should hear a "clinking" noise and the lights should dim in sync with the clicks.

If you are not getting spark to the Glowplugs check the connections to the timer box. If you are getting spark to the Glowplugs you may need to check them. Pull a few out and use jumper cables to briefly energize them. Watch out not to damage the threads. As you test do not overdo it. You can melt them!!

Finally, the fuel. Take off the fuel filter and observe if the fuel filter is empty or full. If empty you have a bleedoff problem in the fuel lines or a bad fuelpump.
Replace the filter with a new one and prime the filter with fuel. If the engine starts and then dies, you must find the bleedoff hole in the fuel line or check the output of the fuelpump with a gauge.

Diesels are harder to work on. I have read about crankshaft sensors causing problems. But for the most part, diesels are still primitive and the basictests have to be done by hand.

Mitsubishi 4D56 engine will not start. Blows fumes into top pan. Behaves like the exhaust and intake are interchanged. Engine turns in the right direction when cranked. Timing is in tact.

Turning in the right direction,does not mean it is in time,have this checked,but check the e g r valve to see if it is stuck open,if not,the valves may be stuck open,or out of time.
