will the blazer potentially throw codes if your check engine light isn't on? thus showing seemingly no issues? i had to replace my injector, though at the time, there was no engine light. it would stall out, and the intake cover/ plenum cover(?) had pooled gasoline in the bottom, leaving me fairly confident the injector had failed, or the fpr could have been acting up.

in hindsight, should i have replaced the fpr while i was in there? or the map sensor?

the sucker has 414xxxkm on it, and it runs, from what i can tell, pretty well. still working out mpg.

 

I replaced a fpr on my 94 and after a couple weeks it failed. I'll start by saying the Dorman replacement i got from autozone doesn't fit right so i had to shave the sides a little. Also I didnt touch the adjuster on it and it was set to 90psi when i first installed it. I got a used set of injectors off a scrap truck and its still doing 100% for 5 months now. I wouldnt say this was a terrible system, but certainly not the best...

 

right. i here ya. sweet you got it going dude.

 

to burt renolds your a piece of **** and should kill yourself. you prolly didn't even replace the nut kit or also called the fuel lines inside the plenum. or you really screwed up on installing the new spider. I have replaced mine ONCE after 180,000 miles and im at 192,000 miles now after the new spider I INSTALLED, YOUR MISTAKE, YOUR PROBLEM. sell that blazer to me and ill have it up and running THE RIGHT WAY in no time.

 

not to imply you're incorrect burt, but i didn't replace the nut kit on mine, though the fuel lines looked fine, and no leaking was evident from them. it simply looked like the injector failed. i bought a refurbished one from napa, installed it, and truck's been running beaut since.

 

ughh I need to quit drinking and righting on forums...... sorry burt but you had that one coming. I hate people that bash on these blazers as I like them....

 

i;ve been thoroughly impressed by this truck so far!
they're pretty rad. little tougher on gas than the b2200

 

I've busted my *** on this car it was my father's first car and noe is mine. I'm not giving up now I believe it receives to much fuel and not burning it fast enough my dad's cousin said one of the cyclindets aren't firing.
