#21 of 27 Fuel pump by nightstick

Dec 08, 2007 (2:53 am)

I have a 2000 Chevy S-10 4 wheel drive pickup with 57,000 miles. I haven't been driving the vehicle regularly, but I would start the truck & drive it around the block. I noticed the "check engine" light came on once when I started the vehicle. The next time I attempted to start the truck it would not start. I priced a fuel pump an auto parts & nearly had a heart attack when they told me $395.00 plus my old one! The reason I haven't been driving the truck is the Universal joints need replaced. I was told today these vehicles have a fuel pump fuse or reset switch somewhere. Are these guys correct or are they just putting me on because I'm a woman? Are there other things I need to check before towing it to get a fuel pump installed? Thanks for any info.

You need to get it towed in and have it properly diagnosed, it could be a number of things.

Use your "nightstick" and bang on the tank with the key on. That will usually get the pump operating and the vehicle will start. That is a temporory fix to get it somewhere to have the pump replaced. I have a fleet of GM vehicles, and this trick works if it's the pump.
 Those pumps are very expensive, and replacing them is also expensive, because the tank has to be drained and lowered to get at the pump. It's a simple job, IF you have the proper equipment, such as a vehicle lift, and a roll around tank with a pump to drain the tank, and refill it when finished.
 While you have it on the rack, get those U-joints replaced..! I don't know why the u-joints would be out at that low mileage, unless you 4 wheel it and it's seen a lot of water and mud. My personal S-10 with 160K on it has the original U-joints. Perhaps get them checked to make sure that is the problem.
 Good luck

I have a 2000 S-10 4x4 too with pump problems, there is a fuse/relay in the fuse block in the engine compartment for the fuel pump. You can swap it with the one for the horn for a quick check. I got a new pump at Advanced Auto for $290.00.

Today's cars have the fuel pump inside the fuel tank. If there is fuel leaking to the point where you smell fuel it is probably some where along the fuel line. Next time you get it started trace the fuel line out hand over hand from the tank to the injectors. It's time consuming but its cheaper than paying your mechanic to do it. Just remember before you crawl under your car make sure you have jack stands under it.

Hi, yes I can. The carb gasket has an electrical grid , If the ceramic grid is damaged, the truck will behave with the same symptoms you have descibed.
The grid is heated and provides proper atomization of the fuel, when it is damaged
I think the piece of crap carb ices up. I had the same problem, rebuilt the carb,but it
didn't help. Replaced the $80.00 gasket and it solved it!
