I bought this 94 blazer w/4.3w cpi 2wd.It would bogg real bad and had to be started with starting fluid. It would idle fine but bogg down and wouldnt go over 60mph.He told me the fuel pump was bad cause the fuel press would jump from 60 - to 30 psi.So i replaced the pump ,relay,fpr and now it won`t start at all just turn over.I bought a fuel press gauge and it showed 20psi.So i got another fuel pump and having the same problem.Its not the filter and the lines arent leaking or clogged.Anyone have any ideas?

 

ever think cat converter??? that would make it bogg down in the first place and would restrict u from goin over 60 if its clogged! That was a common problen with the older body style impalas and what not. Just a thouht in the ruling out process!

 

I removed it and still no luck.. I have post on other forums and people say my syder is leaking.I pulled the plenum and turned the key but couldmt see any fuel leaking.I have checked evrything i know but have no luck.I don`t understand why it won`t run now.All i did was replace fuel pump,relay and fpr.You think that would help not make it worse.

 

fpr bad? still have your old one? put it back on and see what happens, just out of curiosity

 

Did that this morning and still same problem..Can you visual see the spider leaking if you remove the plenum?

 

If you remove the upper intake plenum then yes you can see the spider. If you key is just in the on position with the truck off then there shouldn't be fuel coming out (I had a problem with fuel coming out of mine a month or so ago). Ahve you checked your plugs, wires, cap and rotor? If you are not getting spark then your not going to get it to start. Have y ou checked to see if there is infact fuel coming out of the spider when you try to start it?

Just a couple things to widdle down the list some.
