Wait to start light not coming on and now will not warm by plug
I have a 91 ford 250 diesel. The wait to start light has not been coming on for a while. With warm weather it wasn't a problem. I've been plugging it up at night and long stays but now that has quit working.

Inside of the fuel filter housing is a heating element, a fuel warmer. It is common for this element to break the spot welds of it's mounting plate and ground out against the housing, hence it blowing the fuse every time you try and warm up the glow-plugs. Take the top off of the fuel filter housing and remove the filter, then look into the bottom of the housing and see if the heater is touching the walls of the housing. If this is the problem you should be able to unplug the fuel heater and have the engine start until you get the heater replaced.
Are you waiting after turning ignition key on before actually moving key to start position? My diesel I turn key to 1st position;bells and lights;if engine is cold an amber light that looks like a lamp filiment comes on...wait until that light goes out before engaging the starter.
Your glow plug controller is out, or there is an interruption in its power source, etc. Diesels are coldblooded by nature, and most need glow plugs to heat them up before starting in cold weather. The controller supplies the power to the glow plugs, but if it goes bad, or its supply of power isn't there, it won't start in cold weather, and that wait to start light which is also controlled by it won't come on.
Hello philkatkiele: My name is Roger and I will help you. First thing you need to check is the glow plugs. They will need tested individually. Un plug all 8 glow plugs. Take a test light and hook end to the positive battery cable. Touch opposite end of test light to the terminal end of the glow plug. The test light should light. Touch all 8 glow plugs. Ant that do not light are bad and will need replaced. If glow plugs are burnt out then the controller will flash wait light to early or very fast. The wait light should be on for approximately 10 seconds.If al glow plugs check ok then I would suspect the glow plug controller as the problem. Also if the temperature out side is below 40 degrees the truck should be plugged in. This will help to make the engine start easier. Should you need further help please just ask.Please rate the answer as this way I know it was helpful. Thank You for using Fix Ya. Roger
Not sure about this engine but some diesels have a relay that looks like a voltge regulator , like the one thats for your starter, and a seperate glow plug controller. Find out if you have 2 seperate components and consider checking both.
This what your relay should look like, The 7.3 L has it on top of the engine near the front and between the valve covers. Hold an insulated handled screwdriver to connect both larger studs and keep them connected for 30 sec.s, this jumps the relay. If your glow plugs work after this, then the relay is your problem.
You havent said which engine you have got so I presume it is the 1.8 diesel. Therefore, when you go to start it when it is cold, wait for the glow plug light to go off then wait approx another 15 seconds as the glow plugs continue to heat up after the light goes off before you try to start it.
