Oh no, it one of those ubiquitous "It won't start" threads.

I'll try and be brief and I've not had a chance to investigate as I had to head to work.

Background
1990 245 DL 222k miles. Been repairing and restoring missing interior parts over the last month. When I got the car, I washed the engine thoroughly with a hose and found that the car would not start until it has dried out. Has not been a problem since that one time.

Checked mileage for the first time since restoring the odometer and found I'm getting about 22 MPG.

Have noticed that the idle would stick "high" (1500-2200 RPM) after coming off the highway or after a 10 minute drive. The problem would go away after shutdown.

Anyway, it's been cool, overcast, and rainy for the last couple days.

This morning, I got in the car to go. The engine cranked and fired but stalled without ever really running. I tried for a couple minutes before giving up.

Got out of the car and could faintly smell unburnt gasoline

My initial thought from the wetness (and previous water cleaning experience) is the distributor cap, but I've not been able to test anything yet (Fuel/Fire/Pump) and I won't be home until late tonight so I wanted some advice on what was a likely problem before I go out there in the dark rain to try and get the car going.

I do not think the 1990 has that troublesome fuse/relay under the hood that most complain about. But I do not know if I'm wrong or if there is an equivalent problem.

Cracked dizzy cap seems like an old-school type problem...

Any thoughts??
