Engine Performance problem
2001 Chevy Suburban V8 Two Wheel Drive Automatic 115000 miles
I used a actron auto scanner and it says fuel pump primary circuit malfunction. What would cause this. The vehicle runs rough an will not hardly idol, but these problems did not occur until I changed spark plug and plug wires and one of them came off when my wife went to town the next day. But the only codeit gives is the one I mentioned above.
have the same problem?
