I have had a lot of trouble with my van lately. I started with my water pump being put on wrong. While at the shop the mechanics said me MAP sensor needed to be replaced. NOW they are telling me I need to replace my fuel regulator due to fuel going where is shouldn’t! He said this is something they couldn’t have known until after the MAP sensor was replaced! Are they trying to pull a fast one or could this be true?? Also they are telling me they cannot give me a warranty on the MAP sensor if I do not get the fuel regulator replaced because that can cause it to go bad any day!!!
