Wow nice price.

I agree with Jeff change them all,and do the job once they will start to go out one at a time.

I spoke with John at corvetteinjectors.com today and he was very helpful. I ordered the New Lucas injectors and should have them in a few days. I will post an update once the install is complete. Any other recommended maintenance or inspections while I have the plenum off.

if the wires need changed do that, check the drain hole in the V, it gets junked up. And whats the deal with your av...it looks like a c4 headlight but not

Good idea. I think the plug wires are fairly new so I will check them with the multimeter(what specs should I expect for good condition). Also, what is the best way to check the coils? I already pulled a couple plugs to check the condition and they looked ok. The previous owner said the engine has eaten a few plugs in the past(don't know if this is normal or caused by other factors). Recommendations on plugs?

I reinstalled the new fuel injectors and the fuel rails yesterday before the sun went down. I have a question on the three electrical connectors that attach under the intake plenum. The only part designation I could find was 6ped and 7ped. Am I looking in the wrong place for part numbers or is there a corresponding number. I want to replace the connectors since they are brittle and one clip broke upon removal. I have looked at several online connector websites, but I don't think I have the right part number.

I have also been trying to find the correct replacement for the Ignition Module connectors, but I haven't had any luck so far.

Here are the connectors for a 1990:




The later model LT5's also have a connector for the Secondary Vacuum Pressure Sensor.

Please let us know if you find anything.

Google search is your buddy.

Providing the connectors are not in real bad shape. Sometimes they can be held together with a tie strap or two.

Starter went. Hear a high pitch spinning but it is not engaging the motor. Anyone know where to get a rebuild kit?
