Need help with bad whine at start up

[BurgerLord]

I hate to have my first post be a call for help but I'm new to the ZR1, I just replaced my fuel injectors and all went well until I tried to start it. As soon as it starts it jumps up to 3000 rpm and promptly dies, all the while it has a whining sound (serpentine belt?) it will keep running if I give it gas but something sounds like its rubbing and it does have a smell like hot rubber/plastic. Its most likely something stupid that I missed but any advice would be great.

Hello,

Did you routed the belt the proper way?
Please show/ give us some more information, can you make a video from serpetine belt when starting.
Jumping to 3000 rpm straight possible big vacuum leak, check throttle position/ did you removed the cable and installed it proper back...
How about the fuel pressure....

How more information you give how better the answer back.

Regards, Jitse

Well, I have confirmed that the serpentine belt is not the problem, and I checked the throttle sensor and cables and they are good. I checked all of the vacuum lines and fittings when I reinstalled the plenum and they seemed in good condition, but I could still have a leak somewhere, but I cant check because I don't like the loud whine noise while its running. I guess it must be something wrong with the install of the injectors. What would cause them to make that noise?

Take the accordian off the throttle body and try starting it.
That is not injector sound.
Where is the sound coming from? front, rear,left,right,trans, etc,
If you had a big vacuum leak the motor would stay running at higher idle.

What air duct do you have? Post photo?

[BurgerLord]

I have the stock air duct and I have tried starting it with the accordion off the throttle body and it still has the problems. The sound is coming from the motor but I cant tell what side because it dies before I can get out and I really don't want to run the engine while its making that noise.

Remove the serpentine belt and fire it up for a few seconds.

Then pull the plenum and check everything one more time.

I concur with Pete....I have no idea what would cause that sound except one of the pulleys on the front.

Exactly how did you replace the fuel injectors? and what fuel injectors did you use (but like we said...…..the whine sound seems like metal contact and not air whistle).

[BurgerLord]

The fuel injectors are from SouthBay Fuel Injectors (I know they are not the best), and I followed plenum removal instructions from zr1netregistry and then removed the fuel rails pulled the old injectors replaced with new injectors reattached the fuel rails and replaced the plenum again using the instructions.

Pull the belt off and check for frozen or locked up pulley.
Start motor without the belt.

Last time I heard a sound like that it was the alternator. I’ve also heard the the AC clutch make a high pitched screech. Is the AC off when you start it? I concur with taking the belt off and running it briefly without the belt. That will eliminate any of the belt driven accessories. I doubt the noise and the inability to run are related. But you never know.
