9000 aero won't start-fuel pump?

Hey guys:
My 97 9000 aero won't start,it cranks,but no start.
I switched the DI cassette with a known good one and still no go.
Checked the fuel pump fuse-it's intact.
Could a clogged fuel filter be causing this?
The pump was replaced once before,I think around 130k miles.Car now has 230k-do you think the pump could be gone again?How hard is it to replace?U gotta drop the tank?
Does anyone know the specs for pump output volume?
I cranked it for about 10 seconds with the fuel line draining into a small (16 oz?) Gatorade bottle for the 10 seconds and it filled it about 1/4 of the way,maybe 4 oz of fuel.Sounds a little low to me but I'm not sure.I'm thinking there's not enough pressure to flow it thru the injectors-whatta u guys think?
I guess it could be ignition related but the DI is good and that is the most likely culprit in the ignition system.
Any help would be great.
Thanks in advance.

10 seconds of cranking, my guess would be half a litre from the fuel line. The tank doesn't need to be dropped, the pump is top-fit, under the boot floor. Should be able to search and find a few threads about fuel pump renewal. A lot of people on here fit a Walbro 255. The model number is on this forum somewhere, think it's GSS343 (but don't quote me on that).

I've been thinking about my feul pump because before I bought it it would shut off after a certain amount of gas was left in it, it would shut off. so I'm guessing the fuel system clean was done wrong because he put a full bottle of fuel system cleaner in it and then did not fill the tank up with gas. What do you think is that a possibilty or not?
