Engine Mechanical problem
1993 Nissan Altima 4 cyl Front Wheel Drive Automatic 156000 miles

my veh will only start if someone bangs on the gas tank I have been told that this is the fuel pump by several ppl and then I am told that the gas tank needs to be cleaned. Sometimes the car will start for several days after this is done and then it will have to be done again I am at odds about this I do not know a mechanic and I do not want to be taken advantage of
