i have a 91 s10 blazer and idk wtf the problem is. im gettin fuel all the way to the injectors but not past them. ive replaced fuel pump,fuel filter, am on my 3rd set of injectors,injection unit and im still not getting fuel past the injectors. ive checked all fuses/relays and they are all good? can someone please help me? im about to scrap the whole truck bc i cant figure this out and am spending way to much money

 

Have you checked for voltage at the injectors when cranking?

 

no i havnt. idk why i didnt think of that. thanks for the idea.

 

passenger side reads .04 when cranking and driver side reads .01
idk what this could mean?

 

I think it means that it's time to replace the ECM or the computer.
You could match up a used one.

 

I had that same problem before so I ended up replacing the fuel pump and injectors. Then still nothing happened. I checked the voltage and i'l try to replace the ECM. Where is it located on the 92 blazer? Thanks

 

It should be under the dash, behind the glove box.
