No Start

So after I got the wipers worked out, I decided to support my local tap room and go by some crowlers of local brew. I had fun driving there hitting snowbanks, piles of snow, deep slushy water and generally driving it like the General Lee. I got there no problem, no issues. Parked, went inside to do my business, which took a long time due to the new cleaning standards and then brought my stash to the Disco. I turned the key and it turned over but no start. I tried several times, even giving the gas pedal a quick pump or two, no go. I got out, rocked the car a bit and tried again, no start. For some reason I decided to open the gas cap. I guess to see if I had any pressure built up, but I could not tell. I went back inside and turned everything off, put the key in the first position and I could hear the fuel pump running. I tried again and it started right up, ran a little sluggish and then was fine.

So is this an electrical issue from puddle splashing? If so, what to look for? Or is it a sign of a failing fuel pump or some other intermittent sensor? The PO told me the pump was replaced a little while ago. I regret not trying to listen for the pump the first time but did not. The gauge was reading fine the second time I tried to start it, 3/4 tank, but I did not check it the first time.

Any ideas?

i had that happen, it turned out I had a corner of the ecm cover rotted. water would splash in causing a crank but no start condition. since replacing the ecm no issues.

my '96 would do this occasionally but only in wet weather or after fording a stream. turned out to be rotted insulation on the Crankshaft Sensor wires. fixed that and no more issues.

Look at your fuel pump wiring harness and connections at the pump itself. Might just need a new fuel pump. I change mine out every 100-130k just because it’s better than the alternative.
