Do mean you have hard time communicating with a scanner at the OBDII connector, if so make sure you power at pin16 at diagnostic connector, also we have seen issue with glowplugs not working properly causing hard start when cold and starts fine after warm-up
You can check for glowplugs operation at initial key-of before cranking by checking for voltage at each glowplug connector with a multimeter.

6.0 2004 F-250 was starting hard when cold, replaced glow plugs &harness still starts hard runs rough, glow plug light stays on longer now though


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..

2004 f250 hard time starting on cold mornings like 30 to 40 degrees


Hi

is this a gas version or diesel fuel ? if it is a dieserl then the heater plugs may be shot, you can normally give it 3 heats or lights then it would start easier, if not then this is msot likely the cause otherwise it could be a fuel pump problem, fuel relay fault or blocked fuel filter

Regards

Dan
hope this helps, if not get back to me with more specifics

93 ford f250 7.3 ltr diesal hard to start in cool or cold weather often run battery down have to recharge battery to start. new glow plugs installed 3 years ago. once started good for the day. warm weather...


This engine 'loves' glow plugs! One goes and the others try to handle the amps. Change them and you will have no probs! Other than that, I feel this is about the best diesel truck made!

98 ford f250 hard to shift and wont start unless block heater is plugged in for 2 hrs


i,m assuming you have a 7.3L diesel if so you have one or more bad glow plugs or a bad glow plug module causing the start issue as for the hard to shift issue is it straight gear , automatic or what without more info that is a loaded question back to the start issue your glow plugs have a harness that is actually part of the valve cover gasket about middle of top of valve cover you will see a connector unhook this connector and inspect both sides they like to burn and melt due to poor connections and will also cause this problem

It is possible that some of the glow plugs might not be working. This will cause a hard start and smoking condition especially in cold weather.

F-350 turbo-diesel hard starting


Imagine the white smoke is unburnt diesel. Anybody standing in the middle of it will be able to tell you soon enough.

Most likely culprit is that one or two of the glow plugs aren't getting hot enough. Usually just that the plugs need replacing, but worth checking first that the busbar which runs between them all is getting +12V at the appropriate stage of the process.

Hard starting


Coolant temperature sensor sounds like it went bad. It is reading that the engine is warm all the time, so the computer is not commanding additional fuel for startup. Easy and cheap fix.
