Default 92' LT1 engine keeps stalling

I'm 18 and recently bought a 1992 Corvette with 165,000 miles on it. I drove the car home after purchasing it, and it ran pretty well for about 200 miles. I was driving it to work about 2 weeks later and it randomly just stalled on the highway 4 times within about 5 miles. On the drive home, it did the same thing, it ran fine for about 10 minutes then it started to stall over and over again. It still runs but it's running very rich, and it sounds like a misfire in one of the cylinders, which might be unrelated to the problem.


The diagnostics I've done so far are wiring the fuel pump directly to the battery with a switch, which did nothing. New ignition coil pack. I got a brand-new battery and spark plugs, still no help. I will be changing the plug wires to try and fix what I believe is a misfire.


If anyone has any idea what it could be besides an ECM that would be very helpful because I do not feel like spending that kind of money on the computer for it to do nothing.

are you getting a check engine light and have you checked for codes?
when you turn key on (or jumper the wire) do you hear the fuel pump running?

There is no check engine light, and as I stated the fuel pump is wired directly to the battery and I tested the fuel pressure and it does not go down below what it's supposed to.

you should have a reading around 40 at the fuel rail if everything is good. It will go down some but a large drop or increase means trouble. What reading did you get?
