Re: IML: Fuel problems continue.. On 66 Imp >Any great mechanics out there??



The items Rob mentioned, debris in the tank, plugged in tank filter sock, etc. are all  possible causes for the fuel starvation.   The fuel demand is much greater when going up a steep hill and it sounds like fuel starvation. 
 
 Two other things to consider:  (I assume it has the big block engine.)  The push rod that operates the fuel pump may be worn, making even the new fuel pump marginal when the fuel demand is high.  This would account for hard starting after the stalling because the carburetor is dry and you are trying to fill it with a marginal pump.  This can take a long time.  Maybe longer than the battery will last.  You can replace this by removing the fuel pump and the pipe plug just below the fuel pump opening.  Work the rod out by reaching inside the fuel pump opening with a needle nose pliers or similar tool.  Compare the length to a new one. 
 
A second possibility is a small hole in the fuel line from the tank to the pump. This would allow the pump to draw air in with the fuel.  It may be OK under road load but with a high fuel demand you get more air and less fuel causing the starvation.  You should be able to trace the fuel line from the tank to the pump and observe a damp or dripping line after the car is shut off if this is the case.
 
Good luck.
