Default tips for replacing fuel pump/droping the tank

I think my fuel pump has died in my 1997 Z34. The engine willl crank but wont turn over. I am not hearing the fuel pump come on like I usually do. I checked the fuel pump relay and it is working.
My main concern in dropping the tank is it looks like the filler line is hard to get to, it is tucked above part of the chassis and is held in place by a screw clamp. Anyone have any tips on dropping the tank?

I've used a floor jack to lower the tank once you get the straps off. a transmission jack would work good if you had one.

Thanks for the link and the advice!
Just got finished doing a visual under the car and from what I can tell, its just a matter of undoing the fuel lines at the front of the tank, the back f the tank and the filler pipe. After that looks like its just undoing the front tank strap bolts, and loosening the rears.

Does the chassis get in the way of the rear tank straps at all? And does the exhaust pipe need to be dropped for clearance? It looks like there should be enough cleaerance without loxering the exhaust.


I believe the fuel filter was replaced when I bought the car used 6 years ago. It has been running fine ( save for some transmission trouble) and now just doesnt start up. I do not hear the fuel pump operate when turning the ignition on.

You shouldn't need to move the exhaust, not 100% sure though, as you have a y pipe

Try changing the filter first

Does it have spark?

Although if you can't hear the pump, it's probably toast

i just replaced my fuel pump in my 96 Z like 2 weeks ago... it sucks... would have been easier if my father in law would have agreed with me to drain the tank lol... but with a 1/2 full tank we used two jacks to lower the tank... once we removed the front two lines, and the evap vac lines at the front. then i ended up cutting the filler neck hose as i just could not get it off. i had enough left to reuse the line when i installed it all.

the exhaust did not get in the way. it was also easier to reinstall the straps at the back first then the front as they lined up better. i would deff have an air compressor and or strong shop vac handy to clean the top of the tank before opening it or all the dirt sand and rocks will fall in and could damage the pump again. also replace the strainer too as my tore when i was taking it all apart... i was planing to replace it anyway but if i didnt have it, would have required a trip to the store.

if you have specific questions PM me or post em up and i'll answer them.

on the 5th gen monte you cant just cut a hole in the trunk. IIRC the fuel lines are solid coming out of the top of the tank... you need the tank down to get the pump and sender out. also the sender needs turned and twisted to get out of the tank. would not have room to do this inside the trunk.
