Diagnosing the Abandoned 1993 40th Anniversary Corvette Leaking Fuel Injectors

- In today's video I'll continue working to bring this 1993 Corvette 40th Anniversary Six Speed Coupe back into running condition. After the initial startup, we discovered the new fuel injectors installed by the previous owner were leaking BADLY, requiring an immediate shut down. Watch as I remove the fuel rail, diagnose the source of the leak, and reassemble so that we can get the car fired back up again.

Hope to see you around Houston one day! Very good show! Thank you...
Thanks Robert, glad you're enjoying it. I'm sure our paths will cross soon.
Hey, Bryan! I noticed that your 40th Anniversary is wearing a set of Goodyear Eagle GS-C tires! Cool! Don't forget to tell us all about them and how they compare to the 'Gatorbacks'.
I actually have that on my video "to do" list👍.
Hi Brian. I have been enjoying your videos. This one touched on a subject I can relate to. As my 92 also sounds just like your 93 not firing on all cylinders. I don't have any experience working with fuel injection. I can't believe how easy it is to change the injectors. I'm looking forward to further videos on this it may help with my Vette. Thanks and keep it up. Mike "Bucka" Rugh
Mike, glad you're enjoying the videos. As soon as I turned off the camera at the end of this video, I realized I hadn't done a thorough check of the fuel in the tank. Sure enough, it was completely contaminated with water. Next video will be outlining the process to remove the contaminated fuel and get it running correctly again.
@@VetteSource I'm looking forward to it.
Honestly, I'm more interested on the orange mid-'70"s C3 in the background!
I hear ya, that's one of my favorites. Here is an entire playlist dedicated to it -

Do you have a sequel yet? Also, I am very curious what you will do about the ASR. Please, when you get a chance, tell us what codes the ABD1 is throwing. Thanks.
Working on one now. Should be out shortly👍.
I called you over the weekend i was in Houston
Hey buddy, sorry I missed you👍.
Good afternoon. Looks like u are in Houston area. I'm Baytown. Are u taking any customers?
Hey Jason, I don't do any work on other people's cars, just sell the parts.
@@VetteSource gotcha. Love the vids. I have a 85 iroc-z I've switched the sending unit and pump. The mechanic diagnosed injectors are stuck. They were. Doing that now. Not sure if you have a good set
I usually recommend buying rebuilt originals or the new sets that can handle the ethanol fuel. Even though they're a little more difficult to access on a TPI, a rebuilt set should work fine for your purposes.
Greetings Brian,
I have a non fuel injector question, hope you don't mind.
When changing engine mounts on a 95 C4 is it possible just to jack up the engine to access the mounts??🤔
Thank you Sir!
I have not seen any good videos on that.
Yep, you can jack it up just far enough to get the mounts out. You'll want to be careful to watch the back of the block/bellhousing to ensure you don't crush the fiberglass firewall.
Probably they haven't been made since it's not the easiest job😁.
@@VetteSource Thanx Brian.
I was hoping to give a try myself 1st.
I know my drivers side mount is spent, so I bought some new ones that just came out from Prothane. They don't ship until mid April.
Gotcha, let me know how it goes👍.
Hey, I gotta question for you..... Do you know if the driver side front targa top bolt mount is supposed to swivel?
It will have some end play to enable you to line it up better with the female receiver bracket on the top. It is held in place with a plastic retainer so it stays captive in the header bracket.
@VetteSource ok good! Lol I kinda thought it might be broken but then it kinda seemed like it was supposed to be like that.
Yep, gives you some wiggle room to move the head of the bolt around if you're parked on a slightly uneven surface.
@@VetteSource ya know what's totally fucked?!?! I bought a new top from a guy and I seen that the holes were nowhere near close to each other like normal that I've seen with my broken top but now I know thats why!! I just needed to push down on the left side of the mount and it would have worked!!! I called up dude like what the hell is up with this top!!! I can't get it bolted in!! Lol but that's why, he had a really nice set of sawblades so I just traded the top back for the wheels! Dumbass!!!🤣🤣🤣🤣 and I still have that damn broken top!!!
Yea, the things you always wish you could go back and change😁.
Those look like some cheap bosch clone injectors. I ran some once on a LT1 Now im back to newer delphi style injectors.
For sure, these were definitely Ebay cheap O's. Of course, the guy could have at least put the retaining clips on them to avoid burning the car to the ground😂.
@@VetteSource the clips dont fit on alot of those injectors. they are also not the proper height so they can pull out
Good point. I looked at them briefly before throwing them in the junk parts pile, but noticed the clip cutouts didn't look right, and the height seemed a bit off.
Do you know what lb injectors are in a 1992 corvette? Is it 22lb or 24lb ?
Hey Ross, these will be 22 lb/hrs injectors.
@@VetteSource i keep hearing two different answers IT’s driving me nuts haha what would happen if i use 24lb injectors ?
@rossschultheis8098 yea, it's seems to cause confusion. The 92-93 Corvettes use a speed density system, so they have the 22 lb/hrs injectors. In 94-96, The LT1s had the 24 lb/hrs. It won't hurt anything to use a 24 injector, but you may see it run a little rich on start up until the ECM goes closed loop.
@@VetteSource ok that makes sense what does close loop mean? Need a refresh haha
look like ebay injectors? too soon just started/lol/missing the hourseshoe clips/crazy fire whating to happen
Exactly. Whoever was working on it left them on the old injectors when they replaced them. Amazing that they didn't click on the fact the retainers are VERY necessary if you don't won't fuel spraying all over a hot engine.
