Electrical issues are another common culprit in fuel injection systems. Start by checking the wiring harness for frayed or corroded connections, particularly around the air meter and injection unit. A multimeter can help verify that the correct voltage is reaching the components. For example, the air meter should receive 12 volts with the ignition on. If voltage is low, trace the wiring back to the source, such as a faulty relay or fuse. Replacing damaged wires or connectors is a cost-effective way to resolve electrical problems without extensive disassembly.
Finally, consider the role of vacuum leaks in fuel injection performance. Even small leaks can disrupt the air-fuel mixture, causing rough idling or stalling. Use a smoke machine or soapy water to detect leaks around intake manifold gaskets, vacuum hoses, and throttle body connections. Tightening loose components or replacing damaged gaskets can often eliminate these issues. By methodically addressing these areas—fuel delivery, injectors, electrical systems, and vacuum leaks—you can diagnose and repair many 57 Corvette fuel injection problems at home, saving time and money while preserving the car’s classic appeal.
