So my dad gave me a 1990 240 about 2 months ago. He had just replaced the fuel pump. He said every once in a while it would stall out, then start back up. So I have been driving it and all of the sudden whether I am apply the gas or not it will stall out. A couple of times I was driving and would press the gas, nothing would happen then all of the sudden it would "go" again. It is getting worse. Sometimes when it stalls I just tap on the fuel pump relay under the hood and it goes for a while, but now that doesn't always work. Today I replaced almost every fuse in the car, some seemed to have some corrosion but nothing to bad. Has anyone else had this problem? Or have any advice? Thanks
