    I'm getting an SES light and it's throwing a code 44. I also feel like the motor is being choked and at high RPM's, it seems to cut off. I think I'm going to replace the fuel pump this weekend. It's an in tank and it doesn't look like very much fun to do. How hard is it ? Does anybody have any handly little tips or tricks I should be aware of ? Thanks!

    Have you replaced the fuel filter recently ? If not do that first before getting into the fuel pump. lots cheaper and easier. TBi filters should be replaced every year for best performance and to keep the pump happy.

    Yep I already replaced the filter. I wish it would be that easy again!

    not hard just takes a little time and patience. just have to be careful not to cut fuel lines(if you cut a door in your floor like i did with a sawzall and a drill)or make any sparks after you take fuel lines off. I used some extra carpeting from the house that i had laying around to put between the tank and floor pan when i was sawing..


    make sure you get the strainer too when you buy the fuel pump. First gm dealer didnt have the strainer BUT had the fuel pump. So i had to drive a little ways to my friend at the other gm dealer to get my discount and all the parts. Didnt go there first as i was strapped for time.

    btw mine was a 91 k5

    How about *checking* fuel pressure, instead of assuming it's the pump?

    Fuel Pressure Regulator is good?
