What are symptoms of a damaged Fuel Pressure Regulator in a Blazer 98 4.3L V6 Vortec?
If you Google "Symptoms of a faulty fuel regulator" you will get quite a few hits. If the regulator is bad it may cause either a drop in fuel pressure or an increase in fuel pressure at the rail . A drop in fuel pressure, if severe enough, can cause bad or no idle condition, engine starving for fuel and etc. If the regulator is causing excessive pressure it can cause fouled plugs, black smoke from exhaust and rough engine performance. Before you change the regulator check for cracked, rotted or disconnected vacuum hose. Also you can connect a fuel pressure gauge to the schrader valve on the rail and monitor the pressure to see if it is in specifications, or to see if the fuel pressure drops rapidly after engine shutdown. Hope this helps and good luck with your problem. Dan
