Easiest to just raise the hood, get in the car and turn the ign. key to the on position. You will hear the pump. It will run for a few seconds and then stop if normal. After a few seconds it may run again. If it just runs continuous you have a major leak.it's pretty hard to find a car with "0" leakage. So it is ok if it runs for a couple of seconds, stops and then after a few seconds cycles again.My 91will initially run a few seconds, stop for about 5 seconds and then run for a second or two and then stop again.somewhere on the site there is a reference that gives a service note about what is acceptable for the pump cycle when it comes on and off.I never hear mine when I am driving but sure notice the difference when all 16 injectors are kicked in.

Haven't driven the car yet or a ZR1 for that matter. I have own a 1980 C3 and a 1992 C4 but it's been over 20 years since. I have driven a C5 Z06 and almost bought one but I just like the way the C4's feel. It's not a daily driver and I don't care about comfort, I have a car for that. I used to love driving my LT1, you crawl into and sit low and you feel like your in a race car.
I must say I'm very excited, I was supposed to pick it up today but the weather is crap so I'm going tomorrow morning. I will post some pics.

On the off chance you do need a new vacuum pump you can find these for less than $120,GM used this pump on the KODIAK KICK truck,the only difference is the plug and the $400 others might charge for the stock ZR-1 pump.

The plug at the wireing harness for 90s is different,91-95 are the same. If somebody needed this for a 90 and didn't want to cut the factory harness you could make a short sub harness to go between the 2 with OEM connectors.

I see you live with a dirt driveway. Corvette Central makes a set of filler plates for the area right behind the front tires. Fills in that great big hole right over the shock. These help a lot to keep dirt and dust out of the engine bay. - Steve

Now get out there and spend a few days getting to know every single nook and crany with a cleaning rag. Take her out for a spin and then clean it again.

I recommend you make some plexiglass mud flaps for all four wheel wells. The stones on the driveway will chip the lower sides. I make my own which are 10"W x 9" H and the tears are 12"W x 12"H. The clear plexiglass sheets are 1/16" thick and you'll need to replace them at least annually. The stone chips will fog them up, but your paint will remain flawless.

Mud flaps you can buy are too small for ZR-1 tires.
