I have an impala riddle, please help

[themindbender]

Any help would be nice. I am getting no fuel to the carb. I changed the fuel pump even though it is getting suction. The new fuel pump is giving me the same results. All of the sudden, out of the blue, I started my 68, got about 2 miles down the road and she stalled. I waited about 5 mins. and she started, for another 2 miles. This continued till I got her home. I changed the filter, no avail. then the pump, no avail, and now she won't start at all. Yes, the car does have gas. Now, I opened the line to see if fuel would pump out from the pump itself, and whaala, nothing. I would say vapor lock if it was hot, but she ran fine in the 110 degree weather in Tucson, Az. Now it's in the 40-50 range and no dice. Any help would be nice. It is one of two cars me and my lady use for work, so I have 1.5 days to get it started again. Thanks

HAve their been any leaks under the car? Possibly theres an obstruction in your fuel lines also? Who knows. Run over the fuel system. Worst thing it could be is changing the fuel lines.

Hmmmm.
Look for rust and muck in the bottom of the tank (in back). The pickup inside the tank may have a sock (or screen) on it that becomes clogged with sediment after about two miles worth of "sucking" fuel- which falls back to the bottom of the tank gradually after the motor is turned off.

Yeah, I think dziner is probably right on this one. We had the same problem with our '68 Mustang. In the end we had to order a new tank since the old one had so much rust in the bottom from it's years of sitting. Now days you can get stainless steel tanks, so you should never have that problem again. Tanks(yes, thats the company name) also makes a composite plastic tank, you would just have to check on availability for your car.

Hello, thanks for the info, but now I can't even get fuel to the pump. I have changed the rubber tips at the tank(thought that they might have had a vaccum leak) and blew through the line and heard bubbles.

Why can't you get to the fuel pump?

Try blowing into the fuel tank and see if you get gas on the ground. Many times there is a pinhole in the hard fuel line and it sucks enough air to mess you up.

There has to be a reason. Fuel sock in the tank, crimped or rusted line, pinhole in line, or a big flake of some rust got wedged in the line somewhere. Its easy for you to blow air past an obstruction, but not easy for the pump to suck liquid past it.

Hello to all, well, I found the temp problem. The fuel line had to be primed. As for the other prob, don't know, maybe it was the fuel pump and now it's all good. On to the next problem, the starter. Good luck to all. Oh, the way I primed it was that I put starter fluid in the line and connected it quickly.
