hey everyone, new here. i wanted to ask if the commuters these Mazda's are motor specific. i recently did a swap of 2.3's, i believe, and now my car wont start. Any ideas? how can i tell the difference between the 2.3 and the 2.5? when i jump the starter with an manual button the car will crank but has no spark and no fuel. Any ideas to something i popped or moved during the swap to cause this? please help, i am stumped

 

sorry bout that guys i was confused they are both 2.5's
