1999 Ford F-450 7.3 diesel

It's possible that the fuel pump relay or fuse has failed. Look for any oil leaks before blaming the engine for low oil. Hope this helps!

give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local Ford dealership in the parts department and they be able to print off the pictures and diagrams you need if all fails stop by your local library and get your hands on a Haynes auto repair manual for your truck wish you the best of luck Michigan Man.

that fuse powers pcm fuel heater and some other things. when the fuse blows the pcm shuts down. causing it to not run. usually its the heater that is bad. it is located at the back driver side by the fuel pump. you can unplug it and see if it starts. if so you will need to replace the heater

sounds like eithor the glow plugs are shorting or the timmer is pooched

It is the fuel heater, All you have to do is unplug it.

You should start with the glow plug relay/timer.Check it to see if may be shorted.Remove the smaller wires going to it and turn the key back on,if the fuse does'nt blow then replace it,if it does then you need to unplug the fuel preheater in the filter housing and try the key on thing again,pretty sure it's one or the other.

Replace the glowplug relay.Its faulty.The glow plugs stay on until engine warms up.The engine temp switch then activates the relay to switch off.So it could be the temp switch also faulty.

try this...you can also use a test light instead of a ammeter, but the ammeter is more effective:

hi.check the start selenoid on the pass side of the engine in the engine valley it has 2 battery connections and a little wire it turns on the glow plugs the wire might be comprimised look for the wire chaffing or insulation rubbed off. does it blow out immediatly or over time?

disconnect your glow plug relay and try it, the relay may be shorted out
