just cut off and wont start

[shotime1320]

93 atx with a 255 fuel pump and a ted b lpm and d4u1 computer was driving really hard for about 20 mins and with no warning the sho cut off. i relized i couldnt hear the fuel pump. which i always hear. got sho in the garage and tested at the harness and it ddn't come on..ordered a pump from summit . put it in and still nothing . relized it could be that box at font of engine that controls fuel pump reley and replaced from shosource. still nothing ..tried to test at harness ..pump came on and heard rely box click...so i knew both me repairs did work. but when i turn the key i dont hear that click at the box but when i went to start....rolled over fine ...but didn't start checked fuse for the 4th time and started scratching my head....asked myself ..."what controls the reley and pump" so i changed out my computer and took the lpm out.....still nothing went to pull codes and the check engine light didn't come on when i tried to start th car....tried to pull codes and cil didn't come on...i'm lost does any of the crank or cam sensers or the the grey box on the intake control any of the power to fuel pump or what turn it on? any help would be appreciated thanks

So do you mean that the car just cranks and cranks?

If so then explain how:

Does it crank then sputter? Does it crank and pop? If so then there's spark.

If it just cranks and cranks without anything, pull a spark plug from the front, ground against the frame with vise-grips and have someone crank the car over and check for spark.

Also, smell the exhaust does it smell like raw fuel? Or exhaust smoke?

I wonder also if there's a way to try to switch back to a stock computer.

no smell of anything...the pump is not pumping fuel . it cranks fine ...very quick and strong. what ever went wrong i think controls or effects spark , and fuel pump reley...because neither is working at the same time .all other functions seem to be fine but i have run out of anwsers.
