Check Engine Soon :( - Page 2 - ZR-1 Net Registry Forums

Tom,
Thanks for the info! However at 105$ I'll wait for the exact one

I signed up for notification of when it is available. There arent any other makers of this manual?

UPDATE:
I hear absolutely NOTHING coming from the vacuum pump. So I am going to troubleshoot that right now. Im gonna use a voltimeter on the connector to make sure it has current, look like there is a little bit of corrosion on it. Hopefully thats all that is wrong here, I am dredding a plenum removal. I have a Chilton CD that has a step by step guide for plenum removal that should prove essential. Also (I hate to do this) But a thread at corvette action center has proved VERY useful in diagnosing my problem here is the link http://www.corvetteactioncenter.com/...ad.php?t=14272

Thanks again. Hey by the way anybody ever experience that 3000rpm limiter?

There is a fuse for the secondary pump on the driver side fender well. It's a 10 amp I believe. Check there first to see if it's blown.

Patton · 08-31-2005

UPDATE,

The pump is for sure burned out. However there is a leak under the plenum somewhere as well...

I used the vacuum hand pump and brought it to 10hgs and watched it slowly fall, my spirits fell much faster! DAMN! I dont have the tools like a damn torque wrench or the literature needed for this job. I sure as hell dont have the money to pay somebody,... besides I want the satifaction! Anybody know where someone can get the plenum gaskets? and other such parts? Do they sell new vacuum harnesses? or will I have to rig a new one?
Oh and I used a voltimeter on the connecter to the pump and it read about 13/14 volts. so it was getting juice, Im sure the leak under the plenum made it run itself to death.
Anbody have any advice for someone taking a plenum off for the first time?? I have never even messed with a plenum/intake manifold before... LOL helluva car to learn on! Fvck it, Im goin in!

www.whiteracingproducts.com has the gaskets and the vacuum hoses. You can still get the vacuum pump from GM.

Here is a write up to follow along with for the tear down.

Jeff,
Thanks a million! Very useful! Im sure I will have many more questions to follow though

Hey Patton, It looks like we are neighbors. I'm in Elk Grove. I'm learning my LT5, I've had the plenum off a couple of times (2 to be exact). Maybe we should get together for a cup of coffee, and talk over our cars

Bill

Bill,... Soooooo hows about that coffee whenever you have free time??? LMAO
Im sure you never want to see the underside of a plenum again but If you could help me out here I would be so very gratefull!!!!

Bill · 08-31-2005

Not a problem. I sent you an email. I guess I failed to tell you who I was, you sent it back, I sent it back to you. The plenum is not that bad of a job, just intimidating the first time. Very educational once you can see whats underneath. Refer to the email, after Tuesday will be good for me.

I DO NOT recommend using White Racing Products.

These companies along with others should have what you need.

Why are you bad-mouthing White Racing products on this forum? Kurt White has been a solid supporter of our hobby, and a member of the ZR-1 Net Registry.

You and I have different opinions regarding Kurt and his company. However, your characterization of my post is inaccurate. I did not "bad mouth" WRP, I simply said I did not recommend them, and gave alternative vendors to buy from.

If he is liked by you as a businessman, it is fine for you to say so, just as it is fine for me not to like his business practices. We are both entitled to our opinions, as is anyone else.

Patton · 09-01-2005

Bill,
I havent recieved any emails yet, I just sent one to you however, if you get it just hit reply so we can rule out any misspellings or such.

Thanks again!

oh and Zfactor, thanks much for the alternatives, the more the merrier!

P.S. Check this shyt out... just got a quote from a local dealer.... UGH... And the vacuum harness isnt even listed there because GM doesnt make it anymore. Im gonna use burger king straws and duck tape for my new vacuum harness. If you cant Duck it,... FVCK IT!!
