95 jimmy no injector pulse what could be wrong?

If a 1995 Jimmy is not receiving an injector pulse, it could be due to several issues. Common causes include a faulty crankshaft or camshaft position sensor, which can prevent the engine control module (ECM) from signaling the injectors. Additionally, issues with the wiring or connectors, a malfunctioning ECM, or a blown fuse related to the fuel injection system may also disrupt the injector pulse. A thorough diagnostic check is recommended to pinpoint the exact cause.
