Its looking like a bad fuel pump. Anyone have any suggestions on how to get the fuel pump out. Its the 390 engine with air conditioning. Is it easier to go in from underneath or do I have to remove the power steering pump or (god forbid) the air conditioner. ???? Help! and Thanks.
I think you would have to unbolt the A/C compressor and the p/s pump to access it. You don't have to discharge the A/C- just carefully set it aside. Same thing with the P/S pump, don't drain it, just set it aside. A note, if it still has the stock pump-to carb line, loosen it a the carb end, it will make the reinstallation easy on the pump end. How did it quit running??? Did it have a slow crank when restarting??? Does it have Thermactor air pump system??? In the 1966 T-Bird shop manual section 10, lists causes for stalling.
ENGINE HOT OR COLD
-Incorrect idle fuel mixture
-Engine Idle speed too low (Fast or cold idle adjustment)
-Dirt, water or ice in fuel system
-PCV system malfunctioning or restricted
-Fuel lines restricted or leaking air
-Fuel tank vent restricted (A quick note, The 1966 shop manual indicates the tank is vented by a vent tube on top of the tank, although all repro tanks for 1964-66 are the same, and earlier shop manuals list the vent as being the gas cap)
-Leaking intake manifold or carburetor gaskets
-Carburetor icing (Cold, wet or humid weather)
-Incorreect throttle linkage adjustment to carburetor
-Clogged air bleeds or idle passages
-Defective fuel pump
ENGINE HOT ONLY
-Improperly adjusted or defective carburetor dashpot
-Idle compensator malfunctioning
-Excessive looseness of throttle shaft in bores of throttle body.
