i have a 97 z71 with a 5.7 when it sits for a day or two. it is hard to crank. it drags like a weak battery or the timing is off. once you let go of the key and it kicks back. it cranks easy.
i have replaced the starter and checked the battery and alternator and all that is good. any
ideas what is causing this. oh i just put this motor in and it started doing this about a
week after it was put in.
Are you losing coolant? If so perhaps it's leaking into a cylinder through a bad intake manifold gasket or head gasket. If not, double check all your electrical connections at the battery and starter. Be sure they're all clean and tight. HTH. -Jim
