Question about 1986 Ford F 250

2 Answers

I just bought a 1986 F250 with a 6.9 Diesel in it. In the morning or when it is cold in general it has trouble starting. I am pretty sure this is a glow plug issue. I intend to replace the glow plugs, glow plug controller and the relay so everything will be new. However that has to wait for money. How harmful if at all is it using starter fluid to fire her up when she's cold?

Hi,
I would recommend disconnecting your glow plug relay if you are going to use starting fluid.
With starting fluid in the engine and the glow plugs turn on it may explode the fluid and do head damage. Starting fluid and any kind of ignition source ( hot glow plug ) is like a bomb.

Starting fluid isn't good for ANY engine. Diesels are tough and are generally used to higher compression anyway tho. I've heard that a big help is lighter wieght oil and a block heater when it's cold out. Diesels have to heat the fuel before injecting it.

Charger good, battery good, glow plugs good, but in cold battery needs boosting. what might be the cause?


did you do a cold draw test on battery? this is a diesel i assume, do you have a block heater? if so you should be using it. what weight oil are you using, make sure its the weight for winter months according to factory specs. and possible starter is using excessive draw. when warm is it fine? Even if you put a trouble light under hood it should give it some heat to start in morning.

1991 Nissan Maxima has trouble starting on cold mornings. Once started in the morning, it usually has no problems starting throughout the rest of the day.


Probably the o-rings for the injectors are leaking-this will cause fuel under pressure to leak into a static cylinder, when you try to start it the plug is wet with fuel and the car will be difficult to start. They are pretty easy to replace on early 90's Nissans.

Ford F250 turbo diesel cut out and died as left house this morning, cold morning. Will not start, not even a cough. Have new fuel filters, need location of the filters, anything else I should check?


if you have the 6.0 then the filters are located on top on the motor right beside your oil filter and under the drivers side on the fuel pump, check to see if you have diesel in your bowl where the fuel filter is, no diesel in there your fuel pump might be dead, check fuses to fuel pump and check relay on the passengers side kicker panel, check your owners manual

I have a stanadyne injection pump on a 1986 ford 6.9 liter diesel ,the pump was bought as rebuilt but is way overfueling the engine,a friend and former diesel tech told me the bypass ''button'' may be...


I would take it to a good injection pump shop. Injection pumps are pretty finiky to work on. They require some special test equipment also. Just my 2 cents. Good luck.

Wont start in morning


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

For a short term solution, you could run a small electric heater within the engine compartment which will keep everything nice and warm for your early morning starts.
I remember my father using an extension trouble light and leaving it under the engine compartment during the winters.
