Default Questions

Hi I picked up a 200 Blazer and have some questions. I picked this up as something fun to work on, but not really familiar with GM to much.

Fuel Pressure Test revealed 60PSI during pump run, 50 PSI drop off right after pump stops, then bleed off. So Is the speck for this 62PSI min pressure at all operating conditions? Seems to have some conflicting info

Vehicle will not start, but unsure if there are mechanical issues or not.

Also, found this at the bottom of the tank. Any Ideas?





Thanks!

That is part of your fuel pump unit. I am not sure on the pressure specs for the pump.
