EGR need to be clean/replace.
Over time carbon can built up on the under side of the EGR valve and EGR air passage tube,

Take off the EGR valve and spray WD40 or PB Blaster to help remove carbon.
A 22 rifle cleaning rod will help clean the EGR air passage tube.
Use a shop vac to clean off any carbon inside the tube and egr base.

MAKE SURE you use a NEW erg valve gasket to prevent exhaust leak.
Reconnect sensor connector.

You will see smoke when you start the engine. It's the remainder of the wd-40 cleaner.

Know if my 95 chevy blazer has a spider CPI?


A spider injector is located underneath the intake plenum and this is multi-port. Otherwise you have a throttle body injector system. Vortec engines have spider injectors and they are super expensive to replace ($400.00- 850.00) each ! There is only one spider injector for each engine it has 6 legs/fuel tubes that go to each cylinder.

Fule pump


I bet you frequently run the truck very low on fuel if so you killed the fuel pump when you replace this pump its a good idea to use only a genuine AC DELCO FACTORY pump because the vortec engine needs a MININUM of 60 PSI fuel pressure to start
