All 2 Known Issues
On the 1991-2004 GMC Sonoma, same fuel pump failure issues as the S-10. The in-tank pump fails from heat and debris.
Common Symptoms
- Stalling
- Hard starting
- Loss of power at speed
How to Fix
Confirm low fuel pressure before replacing parts by checking pressure at the Schrader valve on the fuel rail; CPI/Vortec-equipped 4.3L trucks are especially sensitive and typically need about 60-66 psi to start and run correctly, while weak pressure, intermittent drop-out, or excessive current draw points to a failing in-tank pump. Inspect the fuel pump relay, fuse, ground at the frame, and the pump electrical connector for heat damage, then replace the complete in-tank fuel pump module/strainer and install a new fuel filter at the same time; on many Sonomas the tank must be lowered, though removing the bed can also improve access on some configurations. Use a quality Delco or Delphi module rather than a pump-only repair, and clean out any tank debris to prevent repeat failure. Typical repair cost is about $450-$900 parts and labor depending on engine, cab/bed configuration, and whether the sending unit harness also needs replacement.
