it causes the batery to not turn the engine..after a while
the engine will start great as if nothing was wrong..

PS:
CLEAN BOTH TANKS NEW FUEL FILTER AND PUT ON A NEW PUMP ON.
I WONDER IS IT THE PUMP? IT DID NOT DO THAT AT FIRST...

Answer
Hi Richard,

First I need to know what kind of car this is. How did you determine that it is flooding with fuel? It is unlikely the pump if this is a Series III XJ-6 because the pump has no control of the fuel pressure. Fuel pressure is controlled by the fuel pressure regulator.

There is a procedure for testing the injection system. So first tell me what kind of car this is and how did you determine it was flooding?
