Default 88 Jimmy Troubles

I recently acquired an 88 fullsize jimmy, 5.7 tbi, 700R4, with danas and warn manual lock hubs. by the time i got it home the night i bought it, the water pump had started to go out. so i kept an eye on the water level and kept driving it for a few days until i got some days off to work on it, well as soon as i fixed the water pump , the voltage regulator fried in the alternator (and also cooked the plug on the wiring harness which i didn't learn until later) so i had the alternator rebuilt hooked it back up, as soon as i got everything back together i couldn't get the fuel pump to kick on. i found i had a bad ground on the computer so i cleaned everything up put it back together and it fired up, but was still acting like it was running off a generator (this is when i learned i'd fried the plug on the wiring harness) and would die almost immediately if i let off the gas. so i replaced the plug and now the fuel pump won't come on again. anyone have any ideas? i had one friend tell me to replace the engine temp sensor and another say that i may have fried a module in the distributor when i had the bad ground. does this sound feasible to anyone? this has just been eating at me, any help would be greatly appreciated
