Hi, i was helping a friend do a head swap from the single f22a to the jdm f22b dohc non v head. Was told that we did not have to use the balence shafts, so that is the only thing that is not hooked up. Try to start it and it just free spins. WE got spark, and fuel, all sensors are good and tested. timming is right on the money. Just wondering why it would just free spin, it will crank but acks like there is no pressure. running the p14 but also but the original known working ecu and it is doing the same thing. Just seeing if anybody has ran into this issue before.
ps sorr if this is the wrong place to put this topic.
Thank you
