Check that the glo=plugs are not shorting out and that the relay to operate them is operational. continual blowing of the fuse indicates a short in the glo-plug circuit. have the battery fully charged as a diesel needs a fast start rpm to get the air in the cylinder hot enough to ignite the fuel . A fast turning diesel will start with out the glo-plugs so I would suspect that the tips of the injectors may need replacing.

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.

your fuelpump could be causing the fuse to blow as it may be seizing up

there is a short in that wire somewhere and u will have to trace it and look for cracks or frays

Try a new relay first. This may not be good news if that does not work. If you can find the EEC (computer) and unplug it, then replace the fuse-if it blows you have another cheaper part on the circuit thats bad.
If the fuse does not blow, then the EEC must be shorted.
If you have to replace the EEC you may find a kindly dealer with a cash-for-clunker sitting there to violate. Salvage yards have them, Ebay sells them. I have seen them at swap meets for $20. They are a high price part even rebuilt at Dealers or autoparts stores.

My right had turn signal doesn't flash. I changed the bulb and checked the fuse inside the cab? what else could it be?

try cleaning the connector that goes to the fuel pump, sometimes they corrode on inside. If that does not fix, test the wires feeding fuel pump with a multi meter until the condition shows itself again, if voltage drops to zero or very low then wiring problem, if voltage is unchanged with problem and fuel pump is not working and connectors are all clean, try replacement of fuel pump.

I found the solution to my problem. Glo-plugs and fuel filter heater were not the problem. I saw another tip online about the wire harness that comes down on the left intake manifold shorting out and blowing the fuse. Pulled the harness apart and looked at the wires. the were rubbing on the manifold and beginning to wear thru but not completely. Taped them up and covered the wires with a rubber hose but it still blew the pcm fuse under the hood. This was really frustating. I read one more tip online akd this was my last hope. Check the master cylinder pressure switch in the end of the master cylinder. I have a slight brake fluid leak, and it was leaking on that switch. Un-plugged the switch and the truck started. Now it is tome to fix the master cylinder leak.
