I am having some really serious problems since I installed my new motor... The first thing is that the fuel pump will not pump fuel unless I jump the fuel pump and make it turn on. Second my injectors will not fire at all. They are getting voltage and they have the proper resistance. What should I check?

 

Double-check the ECU wiring harness connectors (the yellow ones)!
Same thing happened to me, a loose connector was my problem..

 

any other ideas besides a loose connector?
