    Have generally the same problem with my 1986 Ford 250 with a 6.9 L diesel. At times I need to turn the key 6 - 20 times before the glow plug indicator on the dash will light up for starting. Any ideas what the problem could be?

89 Ford E350 Diesel - two problems 1) no power to instrument cluster, 2) diesel will not fire off without starter fluid...but the glow plug solenoid does click and wait light goes off

You should never use starter fluid when the glow plugs are hooked up. It can cause severe engine damage. You probably need to replace all the glow plugs and the glow plug controller.

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.

1985 Ford 350 6.9 diesel will pull start anytime or start with starter when warm runs good once started have burnt up one starter in the week since buying it

first thing to check is voltage to glow plugs on the start cycle, it should be 12 volts or better, if good the do a resistance test on the glow plugs any burnt plugs will not give you a reading, they should all read about the same

When the glow plug light comes on the truck fires up every time, when u turn the key on and the light isnt on it just makes a clicking noise at the relay by the passenger side battery

The old 7.3 diesel motors are great when they run, their biggest fault is in the glow plug control relay (passenger side fender well), wiring for the glow plugs (harness) and the glow plugs themselves. If you are sure of wiring harness and the plugs, the relay would be the place to start. Hope this helps, and if you have any more questions please let me know.

85 ford 6.9 diesel, the "wait" light does not illuminate, engine turns over but will not start. originally the "engine temperature" light was on, replaced both temp sending units, but still not work. is it...

Have you checked for power on the fuel shut-off solenoid on the injection pump? There are two wires to the pump. One is the fuel shut-off the other is the cold advance. Both should be hot with the key on when the engine is cold. Do you hear the glow plug relay clicking when you turn the key on?

2000 Ford Excursion Diesel has check engine light of P1391

glow plugs preheat the fuel to help the engine start.....when its hot outside its not that bad...the colder it gets the harder it will be to start with bad glowplugs..

86 Ford truck WONT start

Sounds like bad advice. If your glow plugs are bad, the last thing you want to do is try to start it. Remember, diesel engines use these glow plugs like coils in a toaster. Since diesel is harder to burn than gasoline, the glow plugs heat up to a combustible temperature, allowing the diesel to ignite and your vehicle to start. I don't know the reprocussions of trying to start it without them working...but it can't be good.

Glow plugs

no this will not improve the performance of your diesel, the glow plugs are used to ignite the fuel at initial start up and then they turn off.
