i have an 82 300TD and the other day it didn't start. glow plugs and dash light but nothing happened when i turned the key. not even a click. next day it started. drove it a few more times and it was fine, but now am afraid to take it anywhere because i don't want to get stranded.

had a 240D with sporadic no-start issues but with that one i could access the starter to jump it with a screw driver (and it was stick so i would always just park on a hill just in case). with this one is standard and the starter is hard to access so i'm a little hesitant to take it out till i know whats up.

could it be the starter? ground issue? what things should i carry with me to prepare for the next time this happens?
