You should have a test port in the lines heading to the throttle body, and it probably has a spin-on cap on it. Ideally, you would need a pressure gauge, for relatively low pressure, throttle body systems generally run 13-15 psi. As far as injector pulse, you would need an item called a noid light, or a high impedence powered test light. A general 12v test light wont work, and could damage the driver in the ECM. Disconnect an injector, plug the noid light into the connector, and crank. Light flash=pulse.
