well,how bad does the plenum look? THey are suppose to be all black and yucky looking,if any of it has clean runs,etc that means fuels getting in there and washing the soot down. sorta like this :




id check the pressure at the inlet for kicks and giggles.

 

I will have to take another look tomorrow. From what I can see (only through the TB), it doesnt look clean like that. I didnt notice however, that around the base of the plenum it looks like there is some sort of run off if you will where its been leaking through the gasket and creeping down the side.

Tomorrow I will get some pics for comparison but I wont be able to actually look under the plenum until probably friday night / saturday some time.

 

Where r injectors on my 2000 blazer ls if I don't have the spider. It has throttle body

 

You do have a spider assembly, it's under the black plastic plenum. There are 6 injectors, 6 spider lines, (one to each intake port) and the fuel pressure regulator. If you're having trouble, or need help diagnosing a problem, please start a new thread to avoid confusion.
