Engine died on me tonight in the rain...., won't start, helpness please. djet Options

[Hammy]

Driving home from class tonight and the engine sputtered and died on me a few neighborhoods away from my home. (IMG:style_emoticons/default/sad.gif)


Here's what happened :
At a stoplight and noticed the idle speed was dropping suddenly and nearly died. I revved it up to keep it running, and tried to get the rest of the way home.

As I was driving the rest of the way home, the engine was surging and jerking whenever I stepped on the gas more than a small amount.

I pulled off the main road into a neighborhood and there the engine finally gave up and totally quit.

Trying to restart, the engine just turns over and over.

I checked the usual suspects and looked for anything obvious in the engine bay. Couldn't find anything. Once or twice the engine fired up for a short time, idled somewhat ok for 10 secs or so, but then dwindled off and died again.

A long time spent diagnosing and still nothing.

I switched the two main relays on the relay board with each other, and the engine again fired up for a short time, idled and revved up ok, then dwindled and died after 30 secs or so.

Trying to restart again, for a split second it sounds like it's trying to start as the engine turns over, a quick sputter but never fully fires.

That's where I'm left at now.

A few things I do know:
- It started raining today. I've been out and about with no rain tray on, not a good idea but I did it. It was running around fine all day with no symptoms until this.
- Been running perfectly fine for the 400+ miles now since I installed the engine.

This hiccup came suddenly from nowhere.

Engine is a 1.7 djet from a '72....

Could something electrical be shorting out from the water, causing this intermittent and choppy running? I've looked at everything and there's nothing I can see that's a culprit. The only thing I noticed was the switching of the two relays helped it fire shortly.

Is it maybe fuel? I don't know the symptoms of fuel starvation. The pump is pumping and appears to be working fine. Clogged filter? The filter only has 400 miles on it.


Any help MUCH appreciated... I'm going back in the morning to try and get it home.
