I have a 2004 chevy 3500 van. It will not idel. check engine light comes on, runs real rough. Mech. has installed new fuel pump and ignition coil. still no good can anyone help me? very sad sandy
Also... Very limited information to assist.. Could be something as simple as a broken vacuum line or a bad fuel pressure regulator... Or more costly like a bad ignition module or clogged up cat. Honestly though.. It could be anything... Why did you elect to replace the fuel pump and coil? What led you to that assumption? Know this might help lead us to a common problem that could be isolated into just one direction.
