I need to know how to replace the glow plugs on my F350
I have a 2003 F350 6.0 l diesel engine. The symptom is that it's very difficult to start when it's cold out. And it takes 5 minutes or so of warming up before I can drive it. But if I plug in the block heater, it starts easy and I'm good to go right away. I'm guessing I need to replace the glow plugs. How do I do this? I have heard that if they fall apart during dissassembly it can be a disaster. Is that a possibility (a marine told me this who worked on Hummers in Iraq). Thanks for you advice.

Sounds like a diesel. Glow plugs usually need to be warmed up before starting an engine. Smaller diesels either warm up quicker or it is less critical than a tractor trailer. So either your glow plug light is normal letting you know it needs time to warm up or it's letting you know they are weak and need to be replaced. I'd check the owners manual to be sure.
p1248 is in the same error codes as the rest now i have been a mechanic for plenty of years and i will tell you it will be the glow plugs they have a certin limit to glow to start the car if they are worn or nearly gone they wont hold all the fire in them ,,,,Injection start control deviation means the car is not getting even to kick start it it maitanes and shuts the engine down if there is a problem i suggest you changed the plugs and see how you go here is a link to see http://www.patentstorm.us/patents/5778852/description.html
they use diffr, diesels world wide
which one you got?
and try some commas please.
glow plugs too short, plugs are what?
my wild guess, the diesel is hard to start>? and what is the outdoor temperature, and is the fuel fresh? not 3 years old? or water contaminated?
start any engine post with
country (car was sold,which might not be now)
engine displacement. ?????????
then ask a question.
Diesels are more difficult to start in cold climates. Be sure your battery is in top condition - the faster the engine can turn over the better. It may be your glow plugs hard to know without being there to see. Sometimes - as with my excavator - turning over the engine for a few seconds then allowing it to rest for a few will bring the cylinder temp up slightly from initial friction which may just be enogh to bring it into a better cylinder temp starting range. PS never use ether if you also use glow plugs.
the glow plugs are bad when replacing replace the wiring harness as well any ford dealer will not replace just the glow plugs, i know i used to be there diesel mechanic.this is the reason it will start with the block heater is pluged in
Sounds like the glow plugs are frazzled. There is one electrical wire going to a plug, then each plug is connected in sequence. The glow plugs are heating devices used to get the fuel up to temperature before ignition.
They are fiddly to replace, but are relatively inexpensive and the most common source of issues with cold-starting diesel engines (first thing to fail).
Some cars had a 'pre-heat' available with glow plugs, where you simply turn the key part-way to 'on' and you would see a glow plug light come on (looks a bit like a picture of a spring). If you see this light on your van, you can turn the key to turn on the glow plugs and they will pre-heat your engine slightly and make starting easier
dont bother too much with thebullshit recipe .mercedesbenz were built in a cold country and have the cold start tecnique off pat .you need to establish if all the glow plugs are working .,if the engine misses and runs rough when it does start then the glow plugs are not all working but you need to test them with a test light and i would be inclined to think you will need to replace them. do them all as the ones that do work will stop soon.they all seem to go around the same time------------"youdoit "
Hi if the car is a diesel engine then you need to repalce the glow plugs these are used to heat up the diesel for starting the car from cold once the car has been run or if the temp is not to cold then the glow plugs dont need to all work and it will then start.
The problem points to the glow plugs if the car starts ok when it is up to temperature if when the car is upto running temperature and then still has trouble starting then the problem will be with the diesel pump itself. If its the pump and not the glow plugs then this could be an expensive repair. If its the glow plugs then these can be brought relatively cheap and are not to much trouble to replace if you have done this type of repair yourself.
Let me know if your car is petrol or if you need further assistnace then i will assist you further ok
Only thing is Diesels dont use spark ignition. Most reasons for failure of diesels to start is in the glow plug system. Usually just replacement of all glow plugs is sufficient but could be deeper. If you know what your doing you can give a small spritz of starting fluid in the air cleaner and it will start and stay running usually proving a glow plug problem. But please be warned a small spritz. Too much ether can damage a diesel engine. Hope I helped. Thanks
