1996 Base Coupe, new battery, fuel pressure regulator.  Hello all, I had an issue with a $1,600 Corvette I just bought the owner told me it would start up and shut off after three to six seconds. It does do this still. I did the fuel pressure which is good plenty of spark everything seems normal it starts up perfectly fine idles beautiful and then shuts off after three to five seconds. Anyone have any ideas? Thank you in advance.

I'd be suspicious of the factory antitheft system. Have you tried getting any diagnostic codes out of any of the systems?

That....or....

 I would check for spark when the car will not start.

Look at ICM (ignition control module), and then head to the opti-spark.

Water in the Opti-Spark. Mine would go a little farther but did same. I posted pictures quite awhile ago but it was rusted inside. Problem is the pain to get there. The cooling vent was leaking
