CAR WON'T START

1974 Jaguar XKE

Electrical problem
1974 Jaguar XKE V12 Two Wheel Drive Manual 33000 miles

I AM HOPING YOU CAN HELP ME

I HAVE A 1974 XKE SERIES III V 12---IT HAS BEEN RUNNING FINE. LAST WEEK I STARTED IT TO PULL IT IN THE GARAGE. I HAD TO CHOKE IT TO GET IT STARTED. I PULLED INTO THE GARAGE IMMEDIATELY AND SHUT OFF THE ENGINE WITH THE CHOKE STILL PULLED OUT. I DON'T KNOW IF THIS IS PART OF THE PROBLEM BUT THOUGHT I WOULD MENTION.

THE NEXT DAY THE CAR WOULD NOT START-- THE ENGINE TURNED OVER AND I CHECKED FOR SPARK AND FOUND IT. I SMELLED GAS SO I LET IT SIT FOR A WHILE THINKING IT WAS FLOODED-- I TRIED STARTING IT SEVERAL TIMES OVER A FEW DAYS PERIOD TO NO AVAIL. I THEN LET IT SET A WEEK AND TRIED AGAIN WITH NO RESULTS. I REMOVED, ONE AT A TIME, THE HOSES EXITING THE FUEL PUMP AND TURNED THE ENGINE OVER. NO GAS CAME OUT OF THE HOSES. THE CAR, BY THE WAY, HAS OVER 1/2 TANK OF GAS.

AFTER TRYING TO START THE CAR, I PULLED A COUPLE PLUGS AND THEY WERE DRY. IT APPEARS NO FUEL IS COMING FROM THE PUMP. I TESTED FOR POWER TO THE PUMP AND FOUND NONE. I WOULD, VERY MUCH, APPRECIATE ANY SUGGESTIONS YOU HAVE BEFORE I TAKE IT TO THE SHOP--ONE MECHANIC SAID CHECK THE FUSE, ANOTHER SAID THERE IS NO FUSE BUT POINTS INSTEAD, ANOTHER SAYS FUSE/RELAY OR INERTIA CUT OFF SWITCH?
iS THERE A WAY I CAN TEST THE PUMP BY, FOR EXAMPLE, WIRING IT DIRECTLY TO THE BATTERY OR USING A BATTERY CHARGER. IF I USE A BATTERY CHARGER, WHAT AMP SHOULD I SET IT ON. DO YOU KNOW THE AMP RATING FOR THE PUMP AS I DON'T WANT TO FRY IT

Hello and thanks for donating

your jaguar should indeed have a fuse on the fuel pump circuit. This is the 5.3L 12cyl engine correct? If the fuse is good then you could test the fuel pump by supplying 12volt direct power to it either on or off vehicle. Don't let it run but for a second or two so it will not burn up. If it comes on with direct power and the fuse as well as wiring is good then it could be an inertia switch, although i'm not 100% positive your jaguar has one or not . I will search deeper to try and dig up a schematic for your fuel pump circuit.
