1. Remove the rubber boot between the airbox and the sensor plate.
2. Pull your fuel injectors one by one. When the injector is pulled, put the key in the ignition and turn the ignition on - do not start the car. Now, depress the throttle plate, the fuel pump should start running and you should get a good spray out of the injector. After you stop pressing the sensor plate, the fuel pump should stop and after a couple of seconds, the injector should stop flowing and not leak. Repeat for all four injectors. If the injectors do not open, you have a basic fuel pressure problem - check the basics, pump, lines, connections, etc. If you get a bad spray pattern or it leaks, replace the injector. Install all injectors before moving on to the next step.
3. disconnect the coil wire. Remove cold start valve. Leave fuel line and electrical connection connected. Have a friend crank the engine. The cold start valve should spray a fine mist of fuel. If yes, continue, if no, replace.
