my installer just finished installing the heads, cam, intake, pulley & exhaust and said if you turn the key on, the display will not show up, but if you bang around under the dash, it flickers. If you plug in a diagnostics scanner, the lights will stay on. It doesn't show any codes or anything.

help! any ideas? this is a 98 ls1

check all connections and ground wires from under the dash. did they have to do any kind or work under the dash?

no - i don't think he had to do anything under the dash.

Have them check the ground on the back of the left head. Strange electrical issues are usually a sign of a bad ground.

Yeah the ground on the back of the driver side head. there is 2 separate wires, but 3 eyelets that must be grounded. I had this problem before.
