ZR1 sitting for 20 years
Hello everyone, I am looking to purchase a 1991 ZR1 it has roughly 50,000 miles. It hasn?t been driven or started in 20 years, just wanted to know what you think the car might need in order to start driving it again. I know the car was not properly stored, but it was stored in a climate controlled garage.

Re: ZR1 sitting for 20 years
-Oil change
-oil/fuel Filter Change -Fuel pumps -Injectors -Check the o rings at the fuel connections and rails, they can dry up and leak and cause a fire. -Check MAP sensor connection/hoses -Test for vac leaks/secondary intake system vac pump function after startup... can think about trans fluid and Diff

Re: ZR1 sitting for 20 years
If you crank it now the timing chain is going to slap like a mofo until oil pressure is built up so tread lightly there.
read the above^^

Re: ZR1 sitting for 20 years
One other thing to do is once everything is replaced and it's time to start it use the FUEL FLOODED procedure before you do start it,I always do this once my cars been sitting for awhile. Turn the key on,no crank,put pedal to the floor now crank the engine over a few seconds to build oil pressure. The car won't start with the pedal to the floor. This is the procedure for clearing a flooded engine.
