My lady friend asked me to help her with her Blazer 4.3 it was quitting her several different times. I found a bad egr and changed it out. When I went to test the Blazer it died on me. Now it will not start. I am not getting fuel to the plugs. What I have done. checked fuel pressure 60, changed control module in dist. installed new coil, checked all fuses, installed another computer. I changed her plugs and put in a new fuel filter.

What am I missing. Something tells the injectors to fire. Could the egr I installed be bad causing this? Thanks for any help.

 

This might help you if you are having the same problems.
There are 2 wires coming out of the front of your intake. Mine was red and brown, These wires go to the injector hookup under the intake. The Chevy 4.3 has the injector in a bad place under the intake. My problem was the injector wire was pulled out of the injector plug hookup. A $18 dollar part and my Blazer runs great now.

 

Not the EGR.
ECM tells the injectors to fire.
Do you have spark?
