Inherited Mom's low mileage 1970 Buick Skylark. Was running fine until I forgot to gas up! Put a gal. in tank, and it was running ok
Drove 100 ft. to busy intersection, and it died!
With cars repeatedly blocking me in, I tried, and tried to start it, ........no go! Got hand push back to lot, drops in carb, and running again. Drove some 10 blocks, filled tank, drove some 10 miles ok, in heat of day.
Days have passed with no trouble in heat of day, but mornings, (southern Calif), and evenings, and night causing numerous stallings. Car will restart fine, and run a block or whatever, and stall again, and again!
Early on, put fuel system cleaner in tank, and changed fuel filter. Later sprayed carb outside and inside. ......same scenario!
Why does it run fine when the weather is warm, and the car has not been warmed up otherwise?
Please help before some semi smashes me flat! If I had it, I could shove money at this problem for some time!

| Boy it sure sounds like the fuel pump is on it's way out. You said that you put some gas in the carb to get it running again, which leads me to believe that when the engine is cranking over the pump is not supplying fuel. When you put the gas in the carb., the engine fired and had enough RPM to turn the fuel pump and pump gas for a few more miles. The fuel pump should be a mechanical style and most likely towards the front of the engine. I would just replace it and clean all of the fuel lines you can. More than likely running the tank empty stirred up some rust and sludge and clogged the lines between the tank and fuel pump.

It usually starts and runs ok, for a bit, making me think it is not choke or carb.
Should I remove the fuel pump and clean, or replace it? How would I clean it?
Seems like there should be a filter somewhere before the fuel pump, if it is clog prong. But folks aren't supposed to run a old gas tank dry, huh?
It does start most of the time fine, but stalls afterwards.

| Sometimes there is a strainer on the fuel pickup in the tank, but no real filter before the pump on older cars. It's never a good idea to run empty, especially on an older car as you found out.

 Im assuming your still running the mechanical fuel pump. You might try a universal electric pump (keep in mind a pump that uses over 8psi will overpower the needle and seat in the carb and cause flooding) If you have a 4 bbl carb (the stock quadrajet) have it rebuilt by someone that knows what they're do ing! (not your buddy thats pretty good with mechanic stuff) A quadrajet thats working correctly is a great carb!! In my opinion theres none better.
