Mazda3 2.3L cranks but doesn't start with no codes
Ok smart techs here's one that's not normally
asked being a first time Mazda owner I really loved
the car inside out and had plans for custom word
100% 2007 Mazda 3 2.3L 2 months ago I I put
4&1/2 quarts of oil cuz I misread dio stick & blue
white smoke I immediately drained and replaced
valve cover gasket then I had to do timing chain.
Sooo i figured bcuz outa work from pandemic I
mites well do engine haul over so I bout new
pistons,rings the entire works only internal and did it
by the book after 1& 1/2 months waiting for parts
and hands on full time it started but it idled really
rough i had like 5 codes fixed them and nothing
changed on the idle but codes were gone. The only
thing I did change that's new is the chain tensioner
the chains and sprockets still looked good I
repeated all the steps a second round everything.
Now it cranks but doesnt start and i already spent
the same amount as an engine swap. VERY
FRUSTRATING AND STRESSFUL i tested
resistance and DC on all sensors IDK please help I
would appreciate any support I get cuz now I'm lost
and wishing I never bought "Dust Buster" Thanks
everyone for future replies.
