Fuel Pump?

I have an 88 300ZX Turbo. I have been stripping the car down for weight reduction and to do the body work. I have been chiseling and stripping off the sound insulation and doing the body work too and sometimes when I am banging on something with a hammer the car makes a sound in the rear. I think it is the fuel Pump Comming on. The noise does not continue more then 2 or 3 seconds.

Also I temporarily disconnected my electric fan to hear things better. I cannot hear the fuel pump come on when I turn the key and wait for a moment before starting like I can with almost any car.. I usually wait for a moment to let the fuel hit the engine.

Is this normal for it not to come on or not make noise? Since I have stripped the car she wont start. Could that be due to this???

Any imput is appreciated, thanks in advance :)

I'd say thats what it is; you should be able to hear the fuel pump come on for a few seconds when you turn the key.

Some people may disagree with me, but you may want to get under the back with a RUBBER mallet and give a few sturdy taps to around where the fuel pump is. Occasionally, my fuel pump would seize (especially after not being used in some time), and a few taps would coax it back into working again.

ya, at first I thought it was cause I have it all stripped down, maybe some electronic safety feature,, I am use to older cars,, tehn this happend,, and I got wondering about that,, where abouts is the fuel Pump opn these cars?? I am use to old cars,, this is my first Import I am headin out side to work on her again soon,, odds are I can find it unless its hidden out of sight :)

im not sure with the '88, but chances are its in the fuel tank. just check to see where the fuel lines come out of, and give that area a few taps. :)
