87 chevy tbi 350 no fuel

[Markus Escamilla]

So i have an 87 r10 and the fuel pump is not coming on. It had a new fuel pump then it sat for 3 years, now it will not start and i figured the pump messed up again. I replaced it but no prime. I can hear the relay come on for a few seconds then click off. I bypassed the oil pressure switch and i did a tune up and replaced the icm under the distributor cap. Nothing. It is getting spark. I cant find any messed up wires to the pump. I don't know what to do next. Can anyone help lead me in the right direction? The actual fuel sending unit itself has never been replaced, just the pump.
