Default 1994 Turns over but won’t start

Picked up a 94 a few weeks ago and it has driven like a dream until today. Went to turn it on, it turned over but did not start. Tried it a few times and the same. Plan to let it sit an hour or so and try again. I put super unleaded in and it ran great til now. Any ideas?

How soon after the super gas did it act up, since gas prices have been so crazy lately Super isn't getting used nearly fast enough, so you may have picked up some water or junk that clogged up the filter.

So find the fuel test port and if possible put a gauge on and turn key should hit +-35 PSI and hold, if you don't have the gauge pressurize and push the pin see if it has pressure and fuel shoots out.
If possible draw a fuel sample from bottom of tank

Could be a failed opti. Google LT1 opti failure symptoms.
