car wont start without starting fluid - Third Generation F-Body Message Boards

I have a 63 impala with a 80's manifold with a cold start injector but i converted everything to 90-92 MAP. I have the cold start injector plugged in (nothing hooked up to it due to 90-92 wiring not needing it). The car starts up fine with starter fluid and once it warms up you can shut it off and start it back up. Fuel pressure is fine and the car is getting spark. Here is the odd thing. I unplugged the number 3 injector and cranked the car and it started with no issues. I plugged it back in and tried to start and it would not start. I then unplugged the number 5 injector and tried to start the car and it started with no issue. When i plug back in #5 it wont start. Any ideas?

ohm the injectors. sounds like you have shorted injectors when cold that is shtting down the drivers, once warm they keep firing.

Well i figured out what it was my injector plugs were crossed. I had green on 1,3,5,7 and blue on 2,4,6,8 and it should of been reversed. I swapped that this morning and she starts up with no issues now.
