1995 302 to 351 swap problems. HELP!!!

[Chris878993]

I was hoping to get some insight on some issues im having with my 1995 Bronco, i recently did an engine and trans swap replacing my 302 with a 351 out of a 1994 f250. motor is in and for the last few days ive gotten to finally try and start it... but it wont start. i can get it to sputter on ether but not fuel. fuel pump is working, theres fuel in the rail. i pulled quite a few codes and if itll help the codes are 637, 126, 553, 565, 558, 622. Im not sure how id go about dealing with these codes. ive never done an engine swap before so any help would be greatly appreciated. thanks
