OK, I installed a Sniper on my '69 Camaro and have loved until six weeks ago. All of a sudden I’m getting raw fuel dumped and it barely ran. This forum thought it might be an WBO2 sensor and I felt the same too. Ordered a new WBO2 sensor from Holley, no change. Called Holley and they sent me a shipping label to send it to them to check out. Had it a week and sent it back with a “pass inspection” label, so I installed it, now I’m not getting power to my fuel pump. Checked for voltage on the blue wire coming out of the relay, nothing. I’m about ready to go back to my Edelbrock carburetor.
