truck wont start no fuel at tbi

[hopesanddreamsracing]

its a 1995 gmc sierra with a 350. okay heres what i know. i have a full new ignition system from the plugs to ht e distributor. fuel thou i has a new tank, lines pickup and pump. the problem is. the relay blow out on a trail and i need to make it home. most of you might hate me for this. but i jumped out the relay. i ran i power wire from the battery fuse to pin 30 on the relay then jumped it over to pin 87. the fuel pump turned on and the injectors turn on to. it was enough to get the truck home but when i installed a new pump and relay the truck wonted turn over. it just cranked. so i check wireing. i had a connection to ground on pin 30 on the relay which i figured was the sensor down by the started. i believe that the oil pressure switch. so unplugged it and now its good but no power there either. now i look at the computer and the pin 87a and 87 the should have power from the ecm dont and the check engine light isnt even coming on when in acc to run a diagnoises. so did i fry my computer or what. any help please sorry if itsd alot to read but i really need this truck up and running.
