Good day,

The car is a Chevy Z28 with a stock 305 TPI engine. I recently replaced the fuel injectors with the Accel 150819 (all 8). After the fuel rail, intake plenum, and throttle body were reassembled, I attempted to start the engine. The engine was difficult to start, but once it started, engine rpms immediately climbed to redline at which I immediately shutdown the engine. I'm looking for ideas as to where to start with the diagnosis with this engine.

Start with the throttle body. Ensure it is fully closed and linkages are correctly installed. Check for vacumn leakages.
