today i finished up my motor swap, after i put all the fluids in and hooked up all the parts needed to start it, i wasnt priming or getting fuel! im cranking and getting spark so i know its neither.i probe tested the power wire to my fuel pump and sent power to it. the pump turned on... so i also chcecked the wiring for resistance. it was also good. so does this mean my main relay is bad? if so...where is it located and what is needed to replace this so i can get my car running. thank you to whoever can answer this ahead!!!
Oh and also the relay was wokring the night before i took the motor out...so what esle could the problem be?

 

Did you forget to connect a ground somewhere? This is also typical of not connecting the ECU ground at the thermostat housing.

 

i grounded the ecu at the thermostat, i doubled checked that one... ive been reading that the main relay solder goes bad? but why7 would my **** go back over ngiht?

 

check the ground at the tranny to the chassis, try using some starting fluid to see if it helps to start it.

The main relay is under the dash on the driver side, held on by two 10mm goldish bolts

 

Tell us your setup. I bet it's pin A15.

my set up is a 94 japanese b16a it has a obd2 distributor, we re-wired the alternator to obd2 to fit my harness....we used my obd2 injectors, i have a dynamic auto sports obd2a-to-obd1 harness jumper, stock p30 ecu. my fuel pump is a warlbaro 255 pump no problems ever. i checked my main relay today it is working. i went to check my ignition switch but ran out of time...i honestly think its beyond that... i know its the power wire to my pump because it doesnt turn on unless i send power to it directly with the probe...thank you again
