C7 Engines Illustration 2 g01114317 Typical view of the left side of the C7 engine (1) Fuel pressure sensor (if equipped) (2) J500/P500 Injection actuation pressure control valve connector (3) Injection actuation pressure sensor (4) Engine coolant temperature sensor (5) J300/P300 Injector valve cover entry connector. CATERPILLAR C7/C9 ENGINES The Bendix ® BA-921 compressor in the C7/C9 air induction system (see Figure 10) receives its air from the engine's intake manifold (turbocharged). During the pumping condition (loaded mode), the air fl ows from the engine intake manifold through the inlet check valve and inlet line to the compressor inlet port. On some models you could just unplug the electrical connector at the IAP sensor and see if the engine wants to start, if so replace the sensor. The IAP valve and sensors are subject to fail, either of which will not let you start. Your tech will know how to test these and if you have a Cat tech he can just bypass them as Tom says.
