I just put a alt,water pump on my truck last week and now i have to believe the fuel pump went out! Right after work durring the big snow storm!Thank god my buddy waited for me and gave me a ride.So i went to look at it yesterday to see how coverd it was and the snow was up to the windows,got it dug out and was waiting for the tow truck i get a call the driver can't get it too busy!!Ok i understand but i called 7 tow companys and no call backs!!!!!!!!!! To top it all off the pump is $350.00:eek2: I will install my self but! I can't catch a break. THANKS for listening.JOE RIV
Joe I hear ya, some days are tough. Hang in there and keep your head up. The pump is expensive but well worth it to buy the GM part, believe me. As a fleet mechanic I'm the guy that is replacing the fuel pump. The GM ones are more expensive so the fleet manager thinks its a great idea to go with aftermarket. The aftermarket ones are not only much louder but often only last between 25-30K miles. Buy the GM one, the originals last over 100K. And I've NEVER had to replace a replacement GM fuel pump because it failed!
Thanks rob,i just got the truck towed to my house.It starts and dies than will just crank.Any other ideas?Could i get some luck?thanks joe
Joe, I'm guessing you have a 6.0? Not the 8.1? Have you checked fuel pressure yet, or do you have a way to?
It's a 6.0 no codes.and no i did not check fuel pressure i have to go to autozone for the guage.Jim,crank sensor should trip a code?
crank sensor will set a code.try listening for the pump to run when you cycle the key on.have someone turn the key while you listen by the tank.it will only run for 3 seconds or so.try banging on the tank while cranking.if it starts it's for sure the pump.until you get a gauge at least.napa sells a delphi pump which is the same as factory pump.good luck.
Some advice.............If you don't have 5th wheel hitch,etc, unbolt the bed and get some help - set the bed back a couple of feet . MUCH easier to change the pump sender than dropping the tank. Unless your fuel tank is empty.:laugh: 99% of the time, when the fuel pump craps out, the tank is usually full. Mine crapped at 235K and like others have recommended, pay the price for the GM one.
Thanks ted,thats what i did 8 bed and 2 filler neck bolts and 2 tail lite plugs! have to order the gm pump. any part number for it? price? thanks joe riv
I honestly can't believe how many people think this is easier. 2 Straps, 3 quick disconnects, the filler necks and drop. if the tank has a signifigant amount of fuel, drain some before you lift it back up. I've done this hundreds of times back when I was wrenching..
Well after pulling the bed back i found out that the pump was not getting power past the fuse and relay(thanks cris for the help} so i checked the wiring harnes and i found the harnes had rubbed threw and broke the gray power wire!!!!!!!!!:rant: A quick fix so all is well now BUT i have the bed off and the truck has 155k on it should i replace it now?What do you guy's think? thanks Joe Riv
Joe it was very easy.The full tank (22 g) and a very wet floor made my mind up.All my fuel jugs were in my trailer barried in 4ft of snow.
