The fuel pump in post #58 is a great price! Almost too good to be true. BUT, if it's a genuine AC Delco module, go for it.

Anytime you get a slew of DTC's it's best to clear 'em out, and do a General Motors Driving Cycle then post the DTC's in the order they are retrieved.

All 3 DTC's in post #62 could easily be caused by fuel delivery problems. Replace the pump & injector assembly, clear the codes, do the drive cycle, and post any DTC's.

 

My thoughts exactly. Just waiting for my paycheck then I will be buying them. I need to buy something to clear the codes. I have a plan:

New Torque Android Bluetooth OBD2 Check Engine Auto Code Reader Adapter OBDII | eBay

Already have torque installed on my android.

 

finally a post i can help a little with... ran across your thread while doing some searching for issues i'm having.

i have this, works great reading & clearing codes with torque (android) & my 2000 blazer
the one on ebay may be good too i dunno, but i know this one

these things pay for themselves after a while vs. spending time & gas going to autozone, advance, etc. to get codes read
