1993 pontiac bonneville wont start

For the fuel injectors to pulse (open and deliver fuel to the engine) they need a command from the computer. The computer gets information/signal to operate the injectors from the ignition module. The ignition module receives its information from the crank and camshaft position sensors. For the computer to pulse the injectors yet the engine is not running indicates there is an erratic signal being created. About the only way this can happen is if there is a bad ground wire. The computer, ignition module and sensors rely on a good power supply to operate. But more importantly these systems require a good electrical ground. There are several ground wires that are dedicated to these components. Failure of just one of these wires can send the system into total chaos. The result is a confusing condition much like you’re describing. Prove the condition of the grounds and you’ll likely be up and running again.
