March 28, 2011ok so this past weekend my truck was actiing a little funny. Like when I`d go to punch it or accelerate, I would get no power. It would also "hiccup" while i was cruising at a constant speed. Now today it won`t even start. I`m planning on changing out the fuel filter first but was wondering if there was a way to diagnose this problem? Any info would be great. I recently say the post 95 fuel pump. Im not the greatest when it comes to electrical but i have no clue what those guys were talking about. Also how hard would it be to change out the fuel pump? Thanks ahead of time!

March 28, 2011Are you getting a check engine light? If so then you can put a code reader on it to lead you in the right direction. I have seen symptoms like this be both electrical and fuel. You need to check to see if it is firing and check for fuel pressure.
March 28, 2011Im not getting a check engine light The motor is firing and turning over. it just sounds as if its starving for fuel. Also i noticed that when i turn the key to the on position i dont hear the pump kick on like it used to. Which is why its leading me to believe its the pump. Its still the OE pump and its got 176000+ on it.
March 28, 2011sounds like the fuel pump has gone out
if flowing enough to get the symptoms you are describing but not enough to get the truck running
its not a hard change if you have the tools and 4 friends to lift the bed off
March 28, 2011ok well i`ve replaced the fuel filter and the fuel pump relay. Still nothing. I would have checked the pressure but since it won`t start i have no pressure. so i got no pressure, its not throwing codes and im almost positive im getting power to the pump. so my guess would be a bad pump? Im just throwing it out there. im trying to replace the cheap stuff first before i go out and spend 250 buck on a new pump. thatnks for the imput guys! I really appreciate it!!!
March 28, 2011Also i was wondering. Hwne i do pull out the old pump, can i just replace the pump itself? the local auto parts store has a kit that includes the pump, o-rings, wire harness, and heat shrink. Do i have to replace the whole assembly? or cand i just use the OE sender unit?
March 28, 2011The pump on those things is in the fuel tank. I`ve had about 5 of those put in over the years in my 96. I can`t tell how hard it is to do as I had my mechanic do it. 3 of them, didn`t cost me anything as they went out in less than a year. Finally found a pump that worked.
March 28, 2011It`s probably the pump. When mine went out I had the "luck" of the tank being full. I went the route of dropping the tank so I had to disconnect the wires, filler neck, and the straps that held it on. Then came lowering it utilizing a couple floor jacks. I don`t remember exactly everything I replaced but I got the kit from autozone. This was about five or six years ago and the new pump is still going strong. *knock on wood*
March 30, 2011i had to drop the tank on mine, but i still think its an easy job. ask specifically for the pump and its only $40 to $70, depending on brand.
March 30, 2011you should be able to get by with just a new pump, but take a good look at your O rings when you do it. you shouldn`t need a wiring harness and heat shrink. I did one on my 94, and its not to bad to drop the tank, you just need to be careful and be willing to put your hand in cramped spaces to disconnect the lines. it is SIGNIFICANTLY easier to swap the fuel pump with the bed off. so its up to you on how to do it. on my buddy`s s-10, we took off the bed, on my 94 silverado, i dropped the tank. on a full size, the big question is can you get some buddies to help move the bed, or if you have an overhead winch or forklift like i do in my shop, you can use that. if its by yourself in a garage, drop the tank but be careful with the lines. if your tank is full, i would definitely find some friends and pull the bed, or siphon out the tank before hand. But its really up to you. the bed is only about 6 bolts, you`ll need a socket set, extension and cheater bar. (cheater bar can be replaced with air tools if you have them) the tank itself is held up with metal straps that are easy enough to disconnect. either way you should be able to do it in an hour or two with time to spare.
April 6, 2011ok so i got the new pump in. I ended up just dropping the tank. It wasnt as hard as i thought it would be. it was half full uf gas so i had to siphon out alot of it. Also had to replace the front gas tank strap as the bolt on it was bent and rusted a lil. but other than that she cranked up just fine!!! Thanks for all the help guys. Maybe you can help me with my next problem. lol I`ll post it in a new topic. Thanks again!!! s
