'94 DS Gasser sporadic running...

[gornoman]

My brother-in-law (aka Capt. Stoopid - long story) has a '94 DS that sometimes will not run unless he wiggles something under the engine. Then it runs great. It never dies once it's running, but sometimes won't start again.

What is he wiggling, and what does it do?

Can he remove the item, clean it up, reinstall, and expect the issue to go away?

Thanx guys.

The closet thing electrical to the bottom of the motor would be the oil sending unit. I don't think that that would cause the problem.
