COOL, shunt is good, so pump is ok and lines back there ok, filter clean,
the FPR or injectors leak like mad.
5 things can leak, 4 injectors, the FPR
if doing the leak down test, all 5 things can leak (or 6) the 4 injectors, the FPR, the check ball valve in pump or the hose in the tank cracked top of pump to top of rack.
if you do a test with spark plugs out, key on say 10 times, see of gas lands top of pistons, then 4 places are now eliminated.
FPR and check ball, (leak down fails)
the live pressure test low, most times is the FPR if shut passes. and sparks dry. (filter not packed)
