ok so i just swapped a blown up D16z6 for a jdm D15b today was the first time i tried to start it and it cranks and cranks but no start. when i did the swap i added an oil pressure guage that took the place of the stock oil pressure sender. i also added a coolant temp guage where the coolant drain plug used to be those are the only things about the motor that are not stock, the timing belt does spin, the battery is full and the starter cranks. any ideas guys. i might just be over looking somthing simple so any comments are great.
