2002 sentra with QR25DE Ran but had spun all four rod bearing. Remove and rebuilt engine now it only fires #4 plug randomly and won't start. Have both cam and crank sensor, check power and ground to coils. Also check rpm signal with scaner. Any ideas thank you

I have found the problem and repaired it. Used aftermarket timing kit from ebay. Yellow marked links where not in correct spacing. Causing incorrect cam timing and throwing off phase sensor. Thank You
