a few wireing whoas! need help bad

[katillidie]

soo hear we go. first question. is the s13/s14 speed sensor the same. cause i have a s13 ka,s13 trans, s13 ecu. but s14 gauge cluster.... second question and or request. i need a pick of the back of a s14 gauge cluster and harness for the location of the fuel level wire. third. and most important.. i am haveing this problem with the initial start up. when i turn the key the injectors dont open to squirt fuel into the cylinder. but if i take a test light and ground each injector u can hear them open and the motor will start. i swapped ecu's, didnt help. checked the inpedence of injectors. they are 12.4ohms and i cant figure out why i have to ground them manually. once i do so it runs great with no probs. just the first start after sitting.... hellp please

I know some things like injectors have a wire that bolts to the fire wall to ground it. So I would search for it and see if its making a good connection or if it even came unconnected. Correct me if I'm wrong, but I think they are grounded through the firewall. So thats the first place I'd look.
