Question about Ford F250
On some Models the glow plug Relay does not have an integrated Power Relay. This means there is a second Relay before the glow plug Relay that feeds it power.
You should check the wires running to the glow plug Relay for power with the key ON. Check some other wires off of the Ignition switch to make sure your 20 year old Ignition switch is good.
There are some sites which show vehicle wiring. Autozone has a free section after Registering your vehicle but it takes a little sorting through the Help section. There should be a fuse to protect the above Relays.
Make sure you find the Diesel-equipped wiring circuit. Diesel ignitions are different from gas units.

Hello, here is the proceedure. Any questions please ask. Good luck.
The red-striped wires on the 1994-96 DI Turbo engine carry 115 volts DC. A severe electrical shock may be given. Do not pierce the wires.

most likely the relay. its located to the left of the fuel filter( looking at the motor from the front). my experience is that they only last about 50,000 miles. the part costs about $20 at an navistar dealer. remove the cowl over the filter, disconnect the batteries(so you don't short the new relay out if you cross the polarity with a wrench) ,remove the four wires from the ceramic relay, un-fasten the relay from the base. reverse the process with the new relay. CAUTION; do not over-tighten the nuts on the wire studs, you could crack the ceramic relay.(iv'e done it) . hope this helps

Checking and cleaning the battery and conections at the battery and starrter not forgetting the all impotant grounds is a must at first. slow cranking do to bad battery's or conections is a common cause witch will allso decrease the effectiveness of the glow plugs. Allso the glow plugs of this truck do have a problem of going out so a new set wouldn't hurt the other thing to know about this truck is that the light indecater is just a recomendation the plugs themselves will stay on for around two minutes so a delaid start ten to twenty seconds prior couldn't hurt and will help the enitial cold start. Other known hard start problems for this rig consist of worn fuel pump, bad glow plug relay, or high oil presure sender. I allso would refrain from using either by pluging the truck in tell you can find the problem.
