Is this an opti spark symptom?
Lately my 94 T/A has been taking an extra couple of seconds to fire up. I started it last week and it died in the garage and wouldn't restart. Today it started right up. I discovered that the previous owner replaced the water pump and then the computer, so he must of had some problems, but failed to tell me at the time of the sale. I'm sure he got the opti unit wet when changing out the pump. Will a bad opti run sometimes and then leave you sitting the next, or do they die and not restart? I have no experience with this setup.
