Fuel delivery issues

Hey guys i posted a thread a bit ago regarding what i thought to be a bad ecu, i have since figured it is not what i though it was. For some stupid reason

i didnt try shooting some starting fluid in there first. well when i did so it started a sputtered to its death about a second later. So evidently my fuel pump is not coming on. Do you guys have any tricks to diagnose exactly where the problem with the fuel system is? whether it be bad fuel pump or bad fuse or relay somewhere. it cranks and cranks and wont start and when i jump Fp and +B i dont hear the fuel pump turn on and it wont start.

fyi its a 93 pickup 22re manual. thanks guys i could really use the

Honestly dude, I dont mean to be an ass but there 5832949 threads on here regarding EFI issues like this, Could be a number of things, Fuel pump, EFI relay, COR relay..

You realllllly need to search and help yourself on that one...
when searching for 3 letter words such as EFI though, Make sure to use an *asterisk* like "EFI* "
