I just finished my first swap done by myself, everything went pretty smooth except for this. I converted my new car from auto to manual and put a ls in it. I went to start it and it cranks, but wont start. It threw a code 16 for fuel injectors, so I changed my injectors, and nothing happened. I changed the main relay, and nothing happened. I checked all wires and grounds, and found nothing wrong. When I put the new injectors in, it was clearly getting pressure cause gas was coming out of all 4 injector ports. Im not really sure what to do at this point, so any suggestions would be appreciated.

 

Alright, I sprayed starter fluid in the throttle body it it started for a second, so now im sure its a fuel issue. I went to start it again this morning and now it wont even crank . . . ****!!!

 

Not trying to revive old threads, but this is exactly what's wrong with my car. Thanks for posting the solution
