ok so i have a 89 camaro 305. my car's injectors will not fire. i have tested it and i have power but it wont pulse(tested with a test light and a voltmeter) and i do have spake as well. ive replace most every thing that go with the fuel and ignition. ive replaced the fuel pump, fuel filter, computer, ignition model, along with fixed all the wiring in the loom and i bypassed the anti theft crap i. i dont know where to look next

 

Hook up a noid light to the injector, you need power & ground at the injector connector.

 

I checked with a voltmeter while cranking in and there's nothing

 

Wiring diadram time. You need to check the ecm grounds too.
