I have a 2004 6. litre motor that it seems like the glow plugs arent working correctly . This problem started a week ago . When the truck has set over night its hard to get started but if I use the engine warmer overnight the truck will start find. I suspect the glow plug solinoade but dont know where it is located . the older truck is right on the top of the motor where its easy to locate and change out.
Can you help me locate the solinoade on the 2004, F350 diesel, 4 wheel drive.

Re: 2004 diesel hard to start when cold
It sounds more like the glow plugs, the older models had trouble out of the module, but the 6.0 is pretty safe from all those problems. And don't forget to use the correct fuel additive for diesel engines, it helps .

in cold weather diesel gels up and sometimes causes a no start issue..a cetane fuel additive helps with this issue. if temps go below 20 degrees, add a quart per tankful of cetane to the fuel to help start on cold mornings. also diesels require more amperage to crank than gas engines do..thus a stronger battery is needed..
time for replacement of or severe cleaning with fuelinjection cleaner..also if diesel, add cold start to the fuel system..check and replace oil filter type fuel filter since jelling of fuel may be a cold start issue..crack open an injector line and see if injector pump is pushing fuel really well..and see if air cleaner needs replaced blackened element is not good..good luck..
Sounds like not all the glow plugs are working.It should run fairly smooth on a cold start if all of the glow plugs are working..Also you shouldn't drive off on a cold start with a diesel,Its really hard on the motors..At least give them 10 to 15 min on a cold start..The oil in them is a really thick oil and when there drove on a cold start theres no oil lubricating the internal parts and will cause the motor to seize up..You may already no this and dont mean you drive it as soon as you start it i just wanted to let you know..When you get alot of white smoke it could be two things,Theres water in the fuel which will make it not have much power die and smoke..But if it runs fine when its warm theres some bad glow plugs...Hope this helps you and have a great day
Hi, glow plugs does not need changing unless the vehicle struggles to start in the morning or when cold. When testing the glow plugs, they should not take longer then about 5 seconds to become red hot.
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 "
DEPENDING HOW COLD OUT IT IS DIESELS DONT LIKE TO START IN COLD WHEATHER UNLESS THE GLOW PLUGS ARE WARM THIS IS THE REASON FOR PLUGGING DIESELS IN MOST WONT START IF ITS COLD OUT IF ITS NOT THAT COLD OUT IT SHOULD START IF YOU HAVE ENOUGH BATTERY POWER MAYBE THERES NOT ENOUGH FUEL GETTING UP TO THE THROTTLE BODY HOPE THIS HELPS
