You can crack all the lines at the injectors just a little and turn it over till it starts,then shut it off and tighten the lines....about the glow plug solenoid,i used to have a 7.3 years ago in a 89 e350 and the solenoid was bad and caused it to click kind-of fast,now the part im talking about is the square box in the middle of the vehicle towards the back(thats if its in the same location in a pick-up.

Replace glow plug on audi a3 2005

If this is a Diesel engine, the glowplugs would be in a position like a sparkplug. You can replace them as you wish, or replace only the bad one. To determine if a glowplug is bad, you would remove it as you do a sparkplug on a gas engine.

With several of the glowplugs removed, you would place a battery jumper cable on one end of the glowplug, while being careful not to damage its threads. That cable would be connected to the NEG battery cable. The remaining cable would be placed on the Positive(+) terminal of the battery and then you would briefly tough the POS cable to the top of the glowplug.

Do this briefly. You can melt the part. But you need to see if the glowplug will glow. Often the problem with glowplugs is the Timer box. This is the box from where the wires come from to go to the glowplugs.

If you have a glowplug staying dark, or failing to glow well, then it is a bad glowplug. Each should glow the same. That is why you check several at a time to tell what is normal.

I work on Ford diesels and do not know what plastic covers you may have. So just follow the wires that are not on the fuel injectors and that is all you can possibly do.

Ford f-350 diesel 2006 6.0 wont start

Hello, I operated a Ford diesel through Michigan Winters. There are usually issues with the Glowplug Timer or the Power Relay to it. If not that, then you probably have a bleeddown issue in the fuel system.

If you trace the wires off the Glowplugs, it will lead to the Glowplug Timer and then the next part is the Glowplug Power Relay. If you take off one Glowplug wire and put the Hot lead of a Voltmeter or test light on the wire and ground the other testing device terminal you can test it.

Just place the testing device where you can see it or have a helper observe it. Then try a normal startup. The test equipment should show that power is going through the wire. The power should pulse a few times and then stop. If you have NO power at that point, you need to follow the wiring I mentioned earlier and find out where the power stops. That part should be the bad part. You want to restore power to the Glowplugs.

If the wires to the Glowplugs have power, there is the remote possibility the Glowplugs are burned out. To test them yourself, they can be removed and connected to jumper cables and briefly energized. The Glowplugs that stay dark are bad.

The fuel system is another matter. First try a new fuel filter to replace a water clogged filter. It is also beneficial to find that fuel is in the fuel filter and that it is not dry. If the fuel filter is dry, then you most likely are bleeding off your fuel overnight. This will require testing the fuel line by using either a Vacuum tester or air compressor and removing and plugging one line end. The line should not leak.

Diesels absolutely require the Glowplugs to work and they work shorter periods in hot temperatures. You just have the pulses to heat up the Glowplugs. So if the Glowplugs are weak, it will show up in hot weather too.

As for the Injection pump, there are Electric solenoids in some which sometimes respond to a "tap" to get them going again. This will mean pump repair to finally repair it. A Diesel shop can also measure output pressure, which , I want to say can be 1300PSI. Beyond the capability of an Owner to do himself.

I hope this helps you and I would be very interested to know what you found.

06 6.0 diesel wont start however does crank and is internmittent in last couple days till today

Sometimes there is a Solenoid inside the Injector pump which responds well to a hammer handle tap. You can also connect a test light to a glowplug wire and see if the Timer is cycling. You need to have the glowplugs working for your cold starts.

If you have fire at the glowplug wire and are convinced you have fuel, you may need to check each glowplug. Remove at least 1 bank at a time. Hook up jumper cables to each glowplug and being careful with the threads clamp the Neg cable to the base and just touch the Pos to the top.

A good glowplug will get with it instantly. A bad glowplug will stay dark or never get up to the best operating heat. Be careful not to melt the glowplugs, but once you find your best glowplug you will see what I mean. Or you can buy 1 new, and compare all of yours to the new one.

Fuel, there are winter and summer blends. You may have gone to a station with Summer fuel.You need to add fuel thinners and water removers to the fuel in your tanks. Check your fuel separator and perhaps slip in a new fuel filter.

I hope this helps get you going.

Hard starting first thing in the morning when it is cold outside want to see if all the glow plugs are working

Best way to check the glowplugs is to remove them and connect each one to a set of Battery jumper cables. You connect the Neg side to the metal sides of the bottom of the glowplug taking care not to mar the glowplug thread. Then take the POS to the top of the glowplug and touch it.

You can actually melt the glowplug. But judging if the glowplug is good is a matter of comparision. Once you get a good one that lights up quickly, you can judge the rest by how quickly it lights up or if it stays dark.

You can test the individual wires to the glowplug with a test light. You will be limited by the timer which will vary the length of time it powers the glowplug by outside temperature. The timer will also respond to engine heat. That is why the timer does not cycle when the engine has just been restarted.

Once you determine if the glowplugs are good, you can work your way up to the timer. You could have a sticking solenoid inside the Injector pump and be getting a dry start. I hope my solution gives you a very good idea on how to check your system. You can use the reply feature for more questions.

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.

1994 7.3 wont start without ether runs good after it starts turns over good after it warms up .still wont start without ether

There are two areas to check for this problem. The fuel and the spark. There is a Timer for your Glowplugs and you should hear clicking and notice the lights dimming in Synch with the clicking. This should work with your "Start" lamp in the dash.

Test one or two Glowplug wires with a Testlight and see what kind of Spark you have. If the spark is present you need to pull about half of your Glowplugs, if not all, and Test them with Battery voltage. They should be uniform in glowing and be careful not to melt them. Any Glowplug that remains cold or sluggish should be replaced. If no Spark, then check the Timer or replace it. Some models may have a Relay, check with Autozone or Oreillys or similar for parts listing.

The Glowplugs start a cold engine. In a warm engine, the Timer will not engage at a certain temperature. Engine compression will ignite the Ether if the Glowplugs do not work, but compression will not ignite a cold diesel engine.

Fuel, if you have a bleeddown in the fuel system the pump may be weak or there is a hole in the line or bad "O" rings. The Ether simply gets the engine turning fast enough to siphon the fuel and draw it back to the pump. A shop can pressure check the fuel system for leaks or use a "smoker machine" for difficult to find leaks.

I hope this helps and you are happy with the info I provided.

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.

Take off the intercooler and you will see them by the injectors .

You need a good quality deep single hex socket ,say 3/8 drive to suit them (12mm ). and a bar for that socket to turn the old ones out and the new ones in .

Check your 40 amp glowplug fuse as well .

2003 gmc 6.6 turbo diesel sometimes smoke a lot

If the smoke is white smoke and you have it after it has run for a while or when you stop at a stop sign or light it is one of two things or possibly both. I have a 2003 GMC 3500 that had the same proble. It turned out to be a combination of Injector being bad and Glowplugs. Injectors are covered up to 200,000 miles but not the glowplugs. I bought 4 glowplugs of the internet for 10.49 a piece AC Delco New. The dealer replaced all 8 injectors and 8 glowplugs. I paind for 4 GP's and the installation 213.00. Truck has more power and NO white smoke you might need to take it to the dealer. The test for the injectors is about 85.00 but well worth the expense
