have tested all the fuel injection wiring and replaced the computer no problems and tested fuel pressure at the rail is good, but still not getting any fuel into the port. have also replaced the distribitor. and my scanner is not communicating with the car so i cant get any codes. please help

 

What engine are you working on?
Do you know what a noid light is?
Use that to check for injector pulse.
If no injector pulse check to see if the connector is lossing battery voltage or grnd signal.
Becarful not to use a low impedence test light on computer circuits.
Is the secondary ignition firing?(spark at the plugs)

 

it has a 4.9 in it. the computer is not grounding the injectors is what the problem is. but we can't figure out why.
