Hi, sorry you are stuck but you could be stuck in a worse place. I don't know your car but here are some simple things to try.

Think clogged filters, lost fuel system prime, glow system malfunction, low voltage - slow starter, lost compression.

I hope you have not opened your fuel system and lost your prime. This could complicate matters.

Don't crank your starter for more than about 10-15 seconds at a time.

The most simple thing to try is to let the glow plugs cycle a couple times to build up some heat. Turn on the key and count to about 20. Turn the key off for a couple seconds and then turn it back on and count to about twenty, then start the car. If you can see lights dim or brighten that may give you clue when the glow plugs are pulling a load. Try this a couple times to see if seems to make any difference.

Try the same thing and hold the "gas pedal" to the floor when you try to start it.
