Hi guys,

Thanks for the tips on my won't start when hot prblem. After reviewing all the possibilities it appears that the fuel injectors leak.

So, should I have the current injectors cleaned?

Buy new factory injectors.

I read about some aftermarket injectors that are much cheaper from Ecklers are they as good as factory/ are there other options ?

How much should a reasonable mechanic charge for the labor.

While doing the injectors is there any obvoius preventive work that should be done at the same time the car is dismantled to get to the injectors/ 56.000 runs great no leaks.

Thanks again for all your great advice. (I love vette people)

larry,
I just got my fuel system cleaned out for about $120; I guess that wasn't too bad. After I did that, the average MPG went up a little bit and I noticed that I was getting off the line better. Also, I seemed to be traveling a few MPH faster than before: 1500 RPM before I would be at 50 MPH; after the cleaning 1500 RPM would be at 54 MPH.

I was told that fuel injectors cost somewhere around $80; I'm not totally sure because I never totally looked into it. Labor? That's always expensive!

If the your injectors are mildly fouled by either fuel contaminants or combustion by-products, off-engine injector cleaning sometimes solves a leaking injector problem. If your injectors are severely fouled or have rusted internals, cleaning will not be sucessful.


Buy new factory injectors.
New injectors are your best alternative in the case of severe fouling or rusting. New stock injectors are a good choice but the best value in high-performance fuel injectors is the RC Engineering/Lucas injector. It is a rotating-disc type injector with all stainless-steel internals. They are sold by RC Engineering in California. See www.rceng.com.

Aftermarket injectors are available. You can find really cheap, rebuilt units from some vendors. The one thing to remember about injectors is that they're like any other car part--you get what you pay for.

I definitely concur with Hib.

A couple years ago when I replaced the secondary port throttle vacuum system on my ZR-1, I also installed stainless steel Lucas fuel injectors from RC Engineering. I absolutely love those injectors and I was extremely impressed with RC Engineering.

They were very good to deal with featuring prompt service and they sent flow tested my stock injectors and provided me with the test results as well as the test results for the new Lucas injectors that I installed. They are linked in our Corvette Portal section under the Engine subcategory of the Parts and Accessories category. if you use their injectors, please feel free to give them a rating in the portal, or get ready to do up a Product Review for our new Product Reviews Section coming soon!!
