00 7.3L WONT RUN HELP

I HAVE A 2000 7.3L MY PROBLEMS STARTED WHEN I WOULD HIT A BUMP (GOING SLOW) SOMETIMES IT WOULD BOG DOWN AND SOMETIMES STALL BUT WOULD ALWAYS BE FINE RIGHT AFTER I STARTED IT BACK UP, THEN ONE DAY I HIT A BUMP IT STALLED AND WOULDNT FIRE. I TRIED THE CPS SENSOR CHANGED THE FUEL FILTER, AND REPLACED THE FUEL PUMP ON THE RAIL THINKING THAT WAS THE PROBLEM WHICH LEAD ME TO FIND OUT IT WASN'T

THE FUEL PUMP WASNT GETTING ANY POWER I RAN STRAIGHT POWER TO THE PUMP AND STILL NO LUCK.

I CHECKED EVERY FUSE/RELAY THEY WERE ALL FINE SO I WAS THINKING THAT MAYBE IT COULD BE THAT THERES A BAD CONNECTION ON THE COMPUTER? PLUGGING A CODE READER IN IT SHOWS "NO LINK" I TRIED MULTIPLE.

COULD I HAVE A BAD CONNECTION ON THE COMPUTER OR MAYBE FRIED IT SOME HOW?

I take it the pump is not running when you turn the key on but was running when you powered it directly .

Check to see if fuse # 30 is blown , it is for the fuel bowl heater .

i believe i checked #30 that could be the problem even during the summer? i haven't ****ed with it in a few months... just been driving the pos dodge around

like i said before it seemed as though bumps would effect a connection or something and then eventually it "unplugged" or wiggled something loose?

ive had programmers plugged in before and they would program fine and what not. now it just says "no link" when i plug them in....

ive heard of this, but would that have something to do with the fuel pump not getting power also?
