Electrical issues are the most difficult to fix. If you can't duplicate the problem in the shop, you're usually out of luck. It could be a weak relay for things like the fuel pump, a weak electrical connection somewhere, problems with the circuit board inside the engine computer, and so on. It would help if you could narrow down the area of interest like fuel or spark. Carry a can of starting fluid and a spark plug tester and be ready to check things when it quits running or won't start. And check the computer for trouble codes even if the check engine light doesn't come on.

Very hard to say what is wrong, do you have any kind of car history like if the waterpump was leaking or replaced? If so like my 1994 vette the pump is in the front of opti-spark 99.9 percent of the time the water will ruin the opti. I have replacement mine many times, mainly because of the waterpump. if you replace pump you Must change opti-spark, its right there in open after you take out pump.it will save you 4 hours labor time.

Eric, that's a fairly broad problem. Does the 'vette run at all? Does it start? Does the engine turn over but won't start? Does ANYTHING happen when you turn the key to "Start". If not, do you have power to lights, horn, wipers, radio, etc? We need a point of reference to start diagnosing this problem.
