Have an old S10 blazer that was pretty low on gas and now that it has fuel it will no longer start. When I turn the key I do not hear the fuel pump run (don't remember if it ran before this problem or not) and now the truck will not start.

If I dump some gas into carburetor it starts for a couple of seconds and then dies right out. I checked the fuses and they are OK.

I guess it's either the relay, filter or the pump it's self.
Should the fuel pump made noise when the ignition is first turned on or not.

I guess there is no quick and easy fix for this problem.

 

you killed the pump. Time for a ac delco replacement. Dont cheap out on this fix.

 

Just go down the list:
Check your fuse
Check your relay
Check your pump

Fuse is easy.

Find your FP relay, have someone turn the key on, dont start it, and try to feel if the relay is clicking on.

block the tires, crawl under the rig and place your hand on the tank, again, have someone turn the key, DO NOT start it, and see if you can feel the pump turn on.

Replace any bad components until you get to the pump. Pump the problem?
GET THE ACDELCO, get a new filter as well. Don't skimp, be carefull, and follow all the right steps in replacing that pump.

*I dont know if its in the book, but removing the spare tire from underneath the truck on my 4x4 4dr made it far easier to work on the tank. Read the manual.

*I've replaced three cheap pumps, not including the oem that came with it, and some relays on mine.

*Don't forget the petrolium jelly for the O ring and dialectric grease for your wires..
<bad spelling :P

Do it once, do it right.
Hope this helps

 

Thanks for the replies. Changing the pump is not something I'm looking forward to. This old truck is not even worth the cost of a new pump. I only use it to haul our garbage cans down once a week.

How much of a pain is it to change the pump?
I know it involves dropping the tank.

 

you can get the ac delco pump off rock auto for like 40 bucks.


yea,drop the tank. you got a cover,2 straps,loosen the fill/return lines and a round snap ring that holds the sender on. you can do it in a hour with some help

 

The fuel pump uses gas in the tank as coolant to keep the electric pump from overheating. Running them lower than a 1/4 tank on a regular basis kills them.

2 ways of getting to the pump. Your tank is empty so its easy to drop. Or ya can cut an acess hole in the cargo area and make a panel to cover it. Seam sealer and under the carpet nobody can tell. I went to a junk yard and cut a section of the floor out of a blazer. I then took measurements so when I cut my blazer I got it right. Covered the interior with moving blankets and used a cutoff wheel on my 18volt grinder.

 

Sounds like a ton of fun

I just put in 5 gallons so that tank is not empty. Guess I should have put in the gas before running so low.
Thanks for the help.

 

It wont be too bad, just disconnect everything from the tank, and lower the tank slowly until you can get an old hose into the tank via filler port. drain it, yay mower gas, and then finish dropping the tank. Use a friend, some kind of block is nice, but i just use my leg awkwardly....

 

I have used the cheap pumps, and if you're a gamblin man, do it. Mine usually all made it 9-12 months one might have been more.

 

Do I have the drain the tank, can't I just lower it and change the pump with the gas still in the tank?
