The engine type will vary from truck sonoma to sonoma, some may have a 1.9L, 2.0L, 2.2L, or 2.5L I4, or 2.8L, 4.3L, 4.3L Vortec V6.
The coil pack is located on the passenger side of the motor in a 1996 GMC Sonoma 4.3L Vortec Engine. The spark plugs plug into the coil pack eliminating the spark plug wires.
most likely the comp. is bad not letting the injectors work
If it's a 96 vortec 350 / 5.7L then it has 8. 1 per cylinder. If the engine looks like it has a carburetor on the top of it. Then it has 2 injectors and that fuel system is called TBI / Throttle Body Injection.
You have to remove the engine cylinder heads to get to the lifters on the 5.3.
well, the 93 has a spider injection unit in the intake manifold. ten bolts and a gasket...
The knock 1 sensor on a Vortec 4.8 is located on the top of the engine. You will have to remove the intake to gain access to replace it.
There is a fuel diagram for a 94-95 Chevy Blazer with a CPI 4.3 Vortec engine in the service manual. It shows the path the fuel travels from the fuel tank all the way to the injectors.
The sensor is down on the front of the oil pan just behind the crankshaft pully, which is located at the front of the engine.
