  We present the phase-connected timing solutions of all the five pulsars in
globular cluster (GC) M3 (NGC 5272), namely PSRs M3A to F (PSRs J1342+2822A to
F), with the exception of PSR M3C, from FAST archival data. In these timing
solutions, those of PSRs M3E, and F are obtained for the first time. We find
that PSRs M3E and F have low mass companions, and are in circular orbits with
periods of 7.1 and 3.0 days, respectively. For PSR M3C, we have not detected it
in all the 41 observations. We found no X-ray counterparts for these pulsars in
archival Chandra images in the band of 0.2-20 keV. We noticed that the pulsars
in M3 seem to be native. From the Auto-Correlation Function (ACF) analysis of
the M3A's and M3B's dynamic spectra, the scintillation timescale ranges from
$7.0\pm0.3$ min to $60.0\pm0.6$ min, and the scintillation bandwidth ranges
from $4.6\pm0.2$ MHz to $57.1\pm1.1$ MHz. The measured scintillation bandwidths
from the dynamic spectra indicate strong scintillation, and the scattering
medium is anisotropic. From the secondary spectra, we captured a scintillation
arc only for PSR M3B with a curvature of $649\pm23 {\rm m}^{-1} {\rm
mHz}^{-2}$.
