I can't get my Blazer started. It's not getting fuel. I checked the fuel pump and the filter and they are both fine. I was told to check the EST controll, the distribution module, and the magnetic pick up coil. I don't know what any of these are. I looked through my Chilton's manual and I can't find anything about them in there either. If you know what and where these things are, you would be helping me alot! Thanks ahead of time!!!!!
