Was running ok and the service light came on went in to pay for lumber came out and just cranked. Wiggled everything under the hood and it started?
Towed home when it would not start after loading up. Sprayed gas into carb and she fired fine then died out of course. Changed fuel filter last night and injector today, still just cranks.
Looked in my book and it says how to check the pump and check the fuse that I cant find under the hood.
I can jump it it seems by the directions but I would like to check the fuse but cant find it. Also there is only one relay I see under the hood on the drivers fender so I am guessing that is the f pump relay?
Any help is greatly appreciated !!!

my boyfriend owns a 1999 GMC Sonoma and he just recently started having problems out of it. He took his dad to work one day and while waiting he turned the truck off, five minutes later he tries to start it back and it won't do anything. Well, he's changed the fuel pump, checked the wires and many more things but it still will not work. Does anyone know what might be wrong with it? please message me back with anything that you could think of because at this point we would try anything just to get it fixed.
thanks! : )
Have a friend who has a 1997 chevy S10 with 4.3L. Truck ran fine but my friend heard that fuel pumps went bad around 180000 kms, so he decided to replace the fuel pump even though it worked fine. He bought one off ebay after finding prices high and took to mechanic to install and changed filter aswell. Now truck puffs smoke and runs very rough to the point of stalling. Took back to mechanic to make sure all lines were hooked up and proper and he said it was but probably needs a tune up now. After mechanic changed wires, plugs, pcv, rotor and cap the truck ran the same and mechanic has no idea now. Mechanic says the fuel pump might have been bad. Now my friend is tight on funds and cant really afford another pump and has been using my spare vehicle . Is there any info i can use from anyone on possible problems or fixes and solutions. anything I can check, such as fuel pressure and such and where i would check these things. I just want to get his vehicle back on the road and my truck back in my driveway,lol . Thanks ahead
THE TRUCK IS REQALLY HARD TO START. IT WILL START EASILY WITH STARTER FLUID, WHEN YOU GET RUNNING, AND TAKE AIR BREQATHER OFF OF INTAKE IT STARTS RUNNING REALLY ROUGH AND DIES.
BIGGEST PROBLEM IS GETTING STARTED, AFTER STARTING RUNS FINE ANY IDEAS
gas gauge now does not work, and the fuel pump was not working, chsnged the fuse for the fuel pump, now it sounds like it kicks on for a few seconds, but the gas gauge still does not work, and it will not start. tryed a sniff of starting fluid, but wont even fire on that. could this possibly be just ice in the gasline?
Is there any other possible cause for the issue with my new fuel pump? It literally only has a few hundred miles on it. I am planning to blow some air through the fuel lines to see if they are somehow clogged but I have no clue what else could have burned out the pump or if there might be some other issue preventing the pump from activating.
I believe Delco even sends a repair connector with each pump.
Repair connectors can be purchased at the dealer, maybe aftermarket, not sure.
Also, when I am trying to start it and it doesn't start, when I let off the key the engine sometimes sputters and bluish smoke comes out of the TB.
Thanks in advance,
Nick

The power to the fuse box goes through a fuel pump relay, which should energize for a few seconds when you key on. I assumed you checked the fuel pump fuse also? If the fuse is good could be the fuel pump relay or I have seen wires chewed in two by mice or chipmunks after setting for a while.
1. It has a hard time starting, have to jump it often. It turns over just fine but it seems that when I get it hooked up to another vehicle it's like magic and all of a sudden it wants to start. To me it seems that the fuel is having a hard time getting to the engine. I was told most likely the fuel pressure regulator.
2. When it does get started it seems to chug along for the first couple of minutes, like it's not getting enough fuel. Would this be the fuel pressure regulator as well? I was told that when the fuel pump is junk that there is no in between with it, either it works or it doesn't. This is why I'm thinking fuel pressure regulator. Any thoughts?
3. Also I've been driving along and come to a hill and all of a sudden I lose all power. I then can only go 10 mph or it will chug and bog down. To me I would guess fuel issues yet again.
Anyone have any thoughts or suggestions or similar problems with this vehicle?
Thanks for any help!
I have a GMC Sonoma 2001 4 cyclinder.
