The code looks like following:
def parse(self, response):
param = {}
self.send_request(self, param)
def send_request(self, param):
url = "www.sample.com/auto/"
yield FormRequest(url, callback=self.parse_auto, formdata=param, method="POST")
def parse_auto(self, response):
...
Why yield does not work in this code? I would like to reuse the send_request in other sections.

2017-02-26 23:43:18 [scrapy.core.engine] INFO: Spider closed (finished)This is log result. Look at the sent_request function body. There is a change.
Here is fully working code.
All you needed is to return than method from parse

import scrapy, logging
from scrapy.http import FormRequest, Request
