Always seem to fix one problem for another to show up... gotta love blazers for that lol

 

Actually it's back to square one.
Still have P0171, P0174, and P0300. Still have the flashing SES under hard acceleration.
Although driveability is greatly improved.
This misfire is mostly occurring on cylinder 6, so I removed and cleaned the plug. Which looked fine to begin with. Also replaced that wire because I damaged it during the uninstall. Made no difference.

 

I had a blazer yes back that had similar issues turned out to be the fuel pressure regulator maybe give that a check

 

I believe the FPR was actually part of the fuel injector spider I just replaced and therefore is new.

 

Had to open a new account because I lost access to my original.
Anyway. I'm sad to report that this blazer has seen its last mile. It developed a knock and then oil pressure dropped. It will now serve its intended purpose that I originally bought it for as a parts donor for my 2002 Blazer and my newly acquired 2003 S10.
Thanks for all the help with it.

 

I'm sad to report that this Blazer has been driven it's last mile. I was at the McDonald's drive thru when it began to knock and oil pressure dropped off far enough for the "check gauges " light to come on. I had no choice but to drive it home immediately. Oil pressure was present under acceleration but it would not run at idle.
I have since purchased a 2003 S-10 and have begun using this Blazer as a donor vehicle.
Thank you all for your help along the way.

 

Well it was fun while it lasted.

Are you making a new thread for your 03?

 

Well it's an S-10, not a Blazer. Not sure if that's appropriate here. Even though they are 95% identical.

 

There's a few pickup threads on here....but I guess S10forum would be a more suitable home for it.

 

If you end up on the S10 sight that I had a membership with it was a joke and was slowly dieing - Along with mine there is several morf's and several S10 pickups here. Make A build thread and stay here where it's somewhat worth while
