Checking glow plugs for Ford and Chevy diesel engines

If you need to check glow plugs on a Ford or Chevy Diesel engine, run a hot wire from your battery. un plug the glow plug wire and strike the hot wire to the end of the glow plug. If you get a spark the glow plug is good. you should do this to each one, but one at a time then replace the glow plug wire as you go.

My 1987 f250 ford diesel wont crank just clicks like 20 times then when you turn key over only clicks


Check your battery terminals to make sure they are not corroded make sure your wires are not corroded also. That would be the first place I look. You can check the wires by testing the resistance with a ohm meter.

Is the battery in a good condition, it a diesel engine? If so the glow plugs would be the first point of call. Check for power at the glow plug main wire feed, if you have power there then a wiring fault can be ruled out. If not check your glow plug relay and associated wiring. If you have power, I think from memory its only 11 volts, remove the power balance rod that runs across the top of your glow plugs. Then remove the glow plugs and connect them across a battery hold the threaded body of the glow plugs and the negitive terminal and use a piece of wire to connect the small fine threaded end to the positive terminal on the battery. The glow plug should glow a hot bright red within a few seconds of being connected. If it doesnt it is faulty. 1 faulty glow plug puts strain on the other glow plugs. Id replace all 4 if any are faulty. I hope this helps.

a commonrail diesel ford ranger won't start,but it crank


You would need to check the glow plug timer circuit and the fuel supply. Diesel glow plugs can wear out. Make sure the "Ready light" is working and that you hear the timer cycling. Usually the lights will dim as the power goes to the glow plugs.

The glow plug wire can be checked with a Voltmeter inserted on a wire from the Relay timer. The glow plugs are tested when they are removed from the engine. If you get this far, you can use battery cables to test them. They can melt. Ask for more details about proper procedure.

Firstly fit a manual overide to the heater plugs .relay -push button type switch -wire -connectors ,run a wire direct from battery to relay ,other side to heater plug relay output so it feeds all the heaters ,push button inside cab with a 12v feed from ignition switch running to relay then other side of relay to earth ,leave vehicle on charge often on trickle charge where possible ,also on a full tank of diesel put in a litre of petrol to stop diesel waxing up ,nice old rug or blanket over engine and it will first time every time ,only use the petrol when weather below minus 5c though ,great vehicles these peugeots but i do like my ford transit

2000 ford super duty 7.3 diesel will not cold start


you need to have the engine coolant switch checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the computer will make it a rich or lean mixture to start the engine,if it tells the computer that it is 75 degrees the computer will lean the mixture like starting a car in the winter without a choke.
