I have put the motor in and have found that it is only running on 2 cylinders. a guy told me that because i have an hf i have to swap 2 wires at my ecu? is this true and if it is waht wires is it. please help because i want to drive it

 

you dont have to swap any wires at the ecu. The HF was MPFI, all you have to do is plug in the ecu and it should work.

 

then why is only 2 cylinders working? how can i test the injectors? what kind of voltage should i be reading?

 

P.S. i know that i am getting spark and compression
