    I would look for a missing ground, I believe there is one on the intake on this Mazda.. we had one awhile back with the same issue and we found that WE missed a ground! Good luck!

      I would first try holding the accelerator WOT to the floor while cranking. for some reason some POS fords with the mazda built v6s were hard to start , seem to flood after intake manifolds were off , somehow crumbs of soft carbon either find their way between the valve seats or the new intake gaskets seal better and the engine needs to re adapt the IAC to open more or something
