Really bad gas milage

My 94 blazer gets bad gas milage and also runs rough i put a new spider injector and the two fuel lines that plug into the spider and also a new fuel pressure regulator in it and a fuel filter still runs rough and gets bad gas milage i can smell strong gas odor sometimes but its not coming from uner the hood ? the motor only has 80k on it when it is fully warmed up it seems to have low oil pressure when ittling or in park when i push the throttle the oil pressure is normal ? could it be a cracked fuel line in the back ? or bad oil pump / oil sending unit i am about to give up on it

1998 chevy blazer fuel pump is putting out 55 psi but no gas is getting to the cylinders


4.3 TBI (throttle body injector) You dont have a TBI you should be equipt with a CSFI people in the field call this the spider injector,they inject fuel into tubes for each cylinder , as for the fuel pressure it should be 54 psi to 60 psi,and this is for a 4.3, The CSFI system does plug up which causes rough idle due to the poppet valve or seat,to stick open or closed,Ive ran fuel injector cleaner that has been sucesfull maybe you can try that

My 2002 Chevy Blazer won't start?


If you replaced the injector after the plugsthey may be fuel fouled.Pull the plugs and clean them.(you can sandblast them,or use a method I used to use-shoot a little starting fluid on them and use a lighter to burn off the contamination of too much fuel).I can't believe GM kept using this stupid design so long-I remember nearly new Vortec V6s with this same problem in the '90s.

94 cadillac eldorado fuel filter replacement


It could be a fuel problem, but in most cases the rough running would continue at road speed.
You could certainly change the fuel filter and see what happens.
A rough idle but no problems on the road would point to a vac problem or maybe a burnt valve. A fuel or ignition problem would be at most speeds including when you put the engine under a load.
Its possible to have a faulty injector on one cylinder that is bad enough to cause a miss at idle but smooth out on the road, but that is a rare occurance.

You have a leaking injector assembly inside the intake manifold. These trucks had a very common problem with these. You'll need to buy the injector solenoid and tubes, it all comes as an assembly. The top half of the intake needs to be removed to replace it. I've attached a picture that shows the top half off and the injector tubes in question. Some people call this the injector spider as it kind of looks like one. The procedure is somewhat involved but if you google; "4.3 injectors spider repair" I'm sure you'll find many articles documenting it.0781789.jpg

4-3 vortec gas in my oil 1994 s10 blazer . vehicle was running


95% chance its the fuel injector (spider). Take the upper intake manifold off and turn the key on and off a few times and you will see fuel leaking from the spider.

How to manually get a trouble code out of a 95 blazer with vortec


The vortec motor has been known for the so caller spider assembly which is the fuel injection set up inside the intake manifold going bad.The regulator starts leaking wich puts extra fuel into the motor.If that is it you should change the whole assembly.
