Hi i recently purchased a 91 accord and it has no spark it cranks over but no start i’ve put a new distributor in and all the coils and spark plugs but still nothing i also here no click for the fuel pump but i’ve replaced that too i also changed the main relay for the fuel pump and still nothing. when i got the car there was a yellow wiring harness ripped off that goes under the dash not sure if it’s important the harness has grey wires wrapped in a plastic yellow protective shield. fuel went through and spat out of some place near the distributor not sure where from but i tightened a bolt and still nothing.

wiring looks like the yellow one shown in the pic -
Yellow wiring/loom is for SRS = airbags. If one is using an aftermarket steering wheel then they need to unplug this cable and use a resistor to make the light go out in the dash. I wouldn't worry about it. Won't cause a no start.
If you said fuel pump is not getting power then that's where ya start. Lights work, assuming other stuff has power? If you pulled the fuel pump already did you check the voltage on those wires? Also, check your grounds.Comment

Did you buy it with a no start issue? Or did it run and now it doesn't?~Nick~

Ya, you need a manual for all of this stuff. But the main ground off the battery and the transmission ground. And ya, do your interior lights work etc?Comment

yea i bought it with a no start issue but the guy that was working on it got sent to prison and his family wanted the car out of the yard he put lots of new original parts on it his family said one day it just didn’t want to start after they stopped at the store. The lights inside don’t seem to be working besides the dash and the windows but not all windows or locks work i think it might be a electrical issue which i’m not too sure how to fix myself. I have the funds to restore the whole vehicle so i might send it to get fixed if i don’t find a solution myself.Comment

I would check the battery negative terminal and make sure it’s tight, I would then make sure that the engine harness ground is secured and tight on the thermostat.(it is located just under where the bottom radiator hose connects to the block). Though stating your interior lights don’t work, makes me wonder if the inside fuse holder is fried.
is the check engine light on?~Nick~

that’s one thought i had because the negative terminal looks rough i might try getting a new terminal and see if that works and the engine harness ground is a bit rusty not sure if that’ll affect the usefulness of it. Yes the check engine light is on i was thinking about switching the ecu to see if that somehow fixes it.

You need to check the codes.

i checked the codes but the check engine light just stayed still, no flash at all and after i unplugged the wire the check engine light no longer came on it seems to have disappeared so now i have no check engine light not sure what to do.Comment

If it stayed on solid then that's a bad ecu. You mentioned you changed your main relay? Still not starting? Do you have spark? Do you know what the previous owner did to the car prior to you owning it?~Nick~
