Hey guys. I have a 96 Blazer that I replaced both the spider and fuel pump in about a year ago. Started having issues cranking so I checked the spider and the plenum was showing signs of washing so I replaced the spider again. Well, still having problems with cranking. I just checked the pressure and this is what I got.
Key on: Nothing for the first one or two turns. On the third it jumps to 60 and then sinks fast.
Runnnig: 50 psi
Before I replace the fuel pump again is there any chance it could be a relay issue?
