89 civic hb dx not starting

i guys...i have a 1989 honda civic hatchback dx and i kind of having
problems to make it start. i just change the fuel pump and resolder
the main relay but and it makes the click/vibrating sound work so i
know that i am having the gas. my problem is the wires on the ignition
unit, i tested the wires and two of them (which is the blue and white
wire) aren’t working. hope you can help me how to fix it.

thank you in advance!

 

Replace the wires?

 

are you getting spark? if not, check tegger's excellent faq's on
igniter or coil failure.

 

i want to but i don’t know where the blue and white wire goes. do i
need to take off the wires? is there any shortccut? one of the person
that i email said that the blue wire is for tachometer (a/t control
unit) and the white wire is for ecu but when i check the ecu, there’s
a lot of white wires and i don’t even know which one also i don’t know
where to find the tachometer wire. pls. help me. thanks in advance
