I have replaced the fuel pump and filters but no fuel comming out of injectors. I checked they have power going to them and fuel but wont spray. I have also changed the computer and the injectors and still not working. What could it be?

Your fuel injectors are feed with a constant 12 volts all the time with key "on". The ECM grounds the injector coil to make it fire. You can test injector pulse with a test light, but the best way is with a unit called a "noid light". These create a quick flash much the same as the bulb in an ignition timing light. Assuming you have good spark, injector pulse is what I'd check next. Please advise>
