Hello! I've got a 1999 Chevy Suburban LS K1500 and have been having a heck of a time with the power steering system. Essentially the main parts are all new - the steering gear was replaced initially because of significant play in the system. I changed the pump and the lines at the same time. All worked fine for about 6 months when I noticed the pump was leaking - I took it back to Napa for a replacement thinking it would be an easy swap. But upon installing the replacement I had no power steering. I took it back and got another, similar situation only this time I noticed that I have boost if I rev the engine. I tried a 4th.... same issue.
The only thing that hasn't been replaced is the EVO valve/pressure sensor. I checked and it wasn't blocked. I tried disconnecting the sensor and have the same problem. I'm at a loss at this point as to why there's no power assist without higher RPM. Thanks in advance for any tips you might have!
