What should the oil pressure be idling? and at 3,000 rpm hot? Gauge oil pressure is a bit varied between gauges but 50-60-75 psi

What are the secondaries that i need to check with power switch on? This is a bit difficult to explain and in any event if the vacuum pump cycles and then stops and the indicator light is on when you turn the power switch, your secondaries should be working which function at Wide open Throttle (secondary throttle ports.....32 valve of which 16 throttle ports are secondary)

and what time range am i looking for between vacuum pump cycling with ignition key on? A bit varied again but 5-10 seconds to a minute or so is workable....just make sure the vacuum pump (under passenger head light) does turn off for at least a few seconds

I really appreciate all your help and hope to soon be in the ZR1 brotherhood!!
Look for oil leaks under the oil pan and water leaks around the water pump or radiator hoses.

Check the oil level and color of oil (should be light transparent NOT BLACK).
Check coolant level in overflow container under passenger head light.
Check brake fluid level and make sure clutch releases. It is hard to check clutch fluid level as reservoir is hidden under ECM just in front of drivers side behind left front tire high point on engine (should be removable flat black cover held on with Velcro on top of ECM)

Fire it up and listen for any knocks of any kind just in case.
Let it warm up until temperature stabilizes which should be mid gauge between 100 and 260.....around 180 more or less.
Idle should be around 800 after it levels out.
Idle should be smooth.
Rev it up and listen for any hesitation.
Just check overall condition of paint and interior for stains of any sort.

Actually.....Anything except a rare rod knock or other knock and except for any serious dents or exterior damage or interior carpet stains/trim breakage are easily fixable. But when you get it home...do a compression check for starters and then post up photos and any questions you may have

Would be nice if someone from the Forum could stop by and look at the Z with you just in case.

If the fluid levels are where they should be and the items above check out with the clutch disengaging so you can shift easily, you should be able to drive it almost anywhere

Others I am sure will add suggestions....would be nice to post up photos beforehand so we can all take a look
