2004 F250 6.0L starting and ideling issues

battery problem
the engine is cranking too slow and the glow plugs are not working

glow plugs are activated if look on the dash when you turn the ignition just before cranking and you should see a light that stays on for several seconds then goes out and then you should crank the engine ! sometimes when its really cold or the glow plugs are worn try turning the ignition on and off each time light goes out 2 or 3 times to get more heat on the plugs then start ! if this doesnt work then glow plus and system needs checking !

Hi
It sounds to me like it could be a glow plug fault !
The glow plugs heat the diesel before it combusts. An easy way to diagnose this is check your exhaust after cranking on a cold morning if you have thick white smoke then you've probably got a glow plug down on 1 of your cylinders or maybe more
Hope this helps Nick

Two part answer, firstly the glow plug light. The glow plug light on a Ssangyong will only illuminate if the ambient temperature is low enough for the glow plugs to require heating. I did not believe it when I first heard this but sure enough, on the first frosty morning I had the truck, the glow plug light came on for a few seconds. Don't worry about it, the temperature needs to be really cold before it will come on.
Secondly the no-start issue, I had a similar problem with my Ssangyong Rexton. Unfortunately, it is the injector pump, the filter gets clogged with micro-particles of crud. Take it to a diesel pump specialist (as a Ssangyong dealer won't know what to do in my experience and they will charge $000's to fix) and get them to remove and clean the injector pump.

You need to check that you are getting power to the glow plugs, when the light shows on the dash you should have 12V to the glow plugs, if you do have 12V at the glow plugs and it still is having issues starting then your glow plugs may need to be replaced. You can buy them off ebay at reasonable prices.

THIS COMES ALL FROM "WAIT TO START" DO YOU WAIT TO START? IF NOT,THEN THE GLOW PLUGS ARE BUR'NT OUT,WHICH YOU WILL NOT NEED UNTIL FALL. OR MAYBE YOU'VE GOT IT HOOKED ON EITHER,STARTING FLUID,IN WHICH CASE,I SUGGEST YOU REPLACE THOSE GLOW PLUGS NOW.OR ELSE YOU'RE MOVING ON TO EVEN WORSE ISSUES.LET ME ASK YOU THIS,WHY ARE'NT THE GLOW PLUGS BEING DENIED POWER? AFTER ALL THEY START THE ENGINE? AFTER YOU INSERT THE KEY INTO THE SWITCH,WAIT TO START,LIGHTS UP.IF YOU'VE NOT WAITED UNTIL THAT WAIT TO START LIGHT GOES OFF,,,YOU'VE BURNT THE GLOW PLUGS UP.THE ONLY THING TO DO IS REPLACE THEM ALL.IF YOU'VE BEEN USING STARTING FLUID OR EITHER TO START YOUR ENGINE FOR A LONG PERIOD OF TIME,FORGET REPLACING THE GLOW PLUGS,BECAUSE YOUR ENGINE IS ADDICTED TO THE BOTTLE(EITHER) YOU MAY BE ONE OF THE LUCKY ONES,REPLACING THE GLOW PLUGS MAY RESOLVE YOUR ISSUES.BUT,WAIT TO START,,AIN'T NO JOKE. BEST OF LUCK TO YOU & YOURS!

Are the batteries in good shape? Starter slower than before? I hope one of those two. Alternative would be glow plugs. In nice weather it probably starts like a champ but when the temperature drops the glow plugs work overtime to get that initial bang to start. I'm a dodge man but have never driven a Dodge powered by cummins so I don't know about the glow plug light situation. On fords they look like a pigs tail or it just has a "wait to start" amber light. Sometimes a double cycle, letting the light go out and turning it off and then letting it cycle again will make for an easy start.

Dear Sir Glow plug light is on it didn't mean that glow plug faliuer, it mean the power supply is continusly on to glow plug, car will start good even incold condition,please check glow plug timer or show it technician ,but it can cause glow plug failuer in future. Thanks.

if you have changed the glow plugs and it still plays up try changing the leads that run to each glow plug if that doesnt help theres a pre heat box relay which is for the glow plugs should be somwhere near inner wing check it is clicking over after you turn the ignition to start position youll get the pre heat light on the dash once that goes listen ans you should here the box click .hope i could help

Sound like a hide-a-way strobe tube...used as a warning light. Here is a link to a similar item: http://www.swps.com/whelen-hide-a-way-strobe-kit.html. They are used for a wide variety of applications where warning lights are needed, but a roof top light may not be the owners first choice. A lot of people will leave the bulbs in if they get rid of a vehicle because they require a 1 inch hold to be drilled into the light housing. If you remove the bulb,there is a chance that dirt and water will enter the housing. I have them on my vehicles. Hope this helps.
