Some vehicles are particular about proper spark and fuel pressure , just having them won't do and I think yours is one .

I guess you could replace the coolant sensor for a shot in the dark and clean the plugs now that they're fouled

Sounds like you're way overdue for a tune up. Replace the spark plug wires and the spark plugs. Hope that helps! Jim

@beatupchevy what would the coolant sensor have to do with it?

Sometimes a bad coolant temperature sensor will cause a no start condition on GMs. Hope that helps! Jim
