    Holy smacks I can see it already... JK. well for starts... how much source voltage do you have? Get the direct voltage off the battery with nothing on, then have a friend attempt to or crank the engine and read the voltage on your battery while cranking. If it is below 9.6 volts by itself or during cranking you need to charge it or if it wont charge replace it. You need a healthy battery for the ECM to work or to turn any injectors on. If you have that and you still cant read with a code reader or scan tool then you need to check the fuse for the cigarette lighter plug in which is usually the same fuse that your ECM uses. So replace that and you should start to be able to communicate with a code reader/scan tool. Then you can start checking for codes and tracking the problem down. Also make sure your fuel pump is working by checking for pressure and also check to make sure you have spark.. You get all this done and have more info for the next time youcome back if this dont solve your problem.. Battery fuel spark...
