Gary Coleman will not be buried this weekend ... because of a family feud.
A staffer at the mortuary that is holding Gary's remains tells TMZ all plans have been put on hold.
Shielia Erickson, the rep for Gary's ex-wife, tells us Shannon Price is fighting with Gary's parents, so the funeral can't go forward.
Shielia claims Shannon is the executor of Gary's will and has the power to make all decisions regarding the funeral and Gary's estate.
Gary's parents beg to differ.
