Well this one lasted a few months and a few thousand miles .......
Before that a chandler opti would not even start....
i am new to c4, but above info is from PO.
Maybe it is time for a cardone unit from auto parts store down the street, at least I will not have to pay return shipment .........
Funny thing is, I can not see anything wrong with this opti

Where did you get it..even a piece of crap should last more than a few months...I bought mine from Petris because he stands behind it for life and claims he has yet to have a problem with one of his units..he is very well known in the corvette community so I doubt he would sell junk..plus its a custom vented one...399.00

Sorry to hear that. If it is the Optispark, I would be a shocked.
The Opti in the car now is an AC/Delco unit.
I originally tried one from Chandler Motorsports. When my no-start condition remained and I exhausted all my diagnostic skills, I took it to a local garage.
Based on their experience, they insisted that after market engine electronic parts are incompatible with these cars. Regardless of what the aftermarket manufactures say.
So they swapped out the Chandler unit with the AC/Delco unit and the problem was fixed.
The part that was most perplexing was all those endorsements from users on the corvette forum. If it worked for them, why not for me? I don't know. All I know is that it didn't work for me and after the garage installed the AC/Delco unit the car ran."
When I disassembled opti it looked fine, cleaned it up, installed it without water pump(for a test) and same 36 code popped up and it was hard to start.
I knew about opti problems before i bought the car, but I figured the new one would last a lil while. BTW while taking opti out, the work the PO mechanics did loooked top notch.
Sheet Fire, this is a bummer.....

Well like I said after to talking to Chris Petris about his opti I'm confident its the way to go..he uses ac delco's and a custom vented cap with a real gm vent kit..says he has never had a problem with one...I'll find out some day..should be back together this monday...
