Fuel Management!

« on: January 26, 2008, 02:37:41 AM »

Hello Everyone! Just looking for some help.... This past summer a friend of mine talked me into doing some upgrades to my 98
Avenger... Starting with the fuel system... I put a fuel pressure regulator and bigger injectors in her. Now she runs leaner then crap...
Just wondering what I should do to get her back on the road again and maybe some more power thanks alot

How do you know it's too lean? is the computer throwing a code for O2 sensor leanness?

Fuel pump?
Pre-fuel pump sock?
Fuel filter?

lol.

Rob, if you didn't replace the fuel pump filter

You need to. This isn't a 'well it looked ok when we changed it over' situation. Fuel pump strainers are never a reusable item. once you pull a fuel pump out, go spend the measley $7-$20 that they cost.

Try to drink water through a VERY narrow straw to quench your thirst as opposed to just chugging the cup. Use that as an analogy [which i'm hoping since i don't know, that you already understood the necessity of changing the fuel pump strainer].

If your strainer isn't new, it is more than likely clogged. If it's clogged, your pump will not be able to pump enough fuel to the chamber to create the proper mixture, therefore, showing a 'lean' mixture.

When I worked at Advance, I took joy in denying people the warranty on the fuel pumps they bought because we were REQUIRED to warn them that not changing [let alone buying the damn thing on the same ticket whether they changed it or not] the fuel pump strainer VOIDED the warranty the moment they ran ANY fuel through it.

Since the pump isn't too hard to get to, please change the strainer if you haven't with a brand new one.

OK you upgraded the fuel system and regulator but did NOTHING to the computer Huh

You need to get a stand alone fuel management or a SAFC at the very least ...

As long as you're not above researching and reading up on info, this site will probably help you in that department.

pretty much yeah. Just start over from scratch and make sure you have everything [including the SFMU] before you start the fuel system upgrade again.
