i just finished my rebuild i thought i had a fuel problem so i bought starting fluid to see if it would start it did and then checked the fuel pump to see if it was working it was. injectors looked good so now what?

 

Check for spark.

 

What is your question? Trying to fig out why it wont start with the regular fuel?
First make sure your fuel and return hoses are connected correctly. If you have an 86 as your name suggests, make sure the resistor pack is connected(passenger side strut mount), then check if the injectors are opening.

 

ok now what
