Vacuum pump - ZR-1 Net Registry Forums

zig · 08-13-2013

Still trying to learn the differences in the ZR-1 from the 96 LT-1 I have. When I turn the ignition on I hear the vacuum pump run and then shut off. How long should iut remain off before it kicks back on? Mine shuts off for a couple seconds then turns back on for about a second. The cycle repeats until I start it up. Is this normal or do I have a vacuum leak?
