swap issues 1993 hatch with 1995 si chassis and engine B18b

- Tue Aug 30, 2011 6:51 am #269590 so i havent been around for a few months or so and i finally got back to my girls hatch,i got a 1995 civic si with a b18b swap that was running mint.I pulled all the Si stuff engine,dash harness all the way up to the fuel pump.I left the cruise stuff out and the SRS as well( air bags) and the power sunroof stuff.i had juice,main relay,fuel pump primed,but no crank.I checked all my grounds under the hood,cleaned and reinstalled them and still nothing.i checked to see if the two nuetral safet switches i took from the Si were installed properly and ingauging when pushing the clutch and looks like theyre.

i even tried to just jump the starter and it wont even arc
Now all of a sudden out of nowhere i have nothing,no dash lights nothing.
Ive been chasing wires with the test light for hours and cant for the life of me figure out why its like doing nothing,no main relay now ,dash lights,nothing...so wierd any suggestions,ideas or advice on my issue would be greatly appreciated.

the civic is a cx with a VX chassis harness and i was having issues getting spark on the y8 swap,so i bought a complete si with b18b to toss into it after being told that my issue lies within the VX chassis harness thatwas put into this hatch.

i check and even sanded the freshly painted bay and grounds and remounted them

i now am rpping out the SI chassis and putting the VX one back in and hope it works.at least everything on it worked just no spark

i'll let you guys know how it goes

- Wed Aug 31, 2011 8:42 am #269767 so its running,buddy added another ground to the starter,which doesnt make sense to me,but it worked,the power wasnt getting past he firewall and we dont know why,but grounding the starter fixed the issue...its ot throwing any codes or anything like that but its idling at 1000 and when you give it gas its like sounds like a wrx and seems very weak when accellerating.Thinking old fuel ,but if anyone has had this issue let me know what itwas for you

thanks for the hep so far guys :)

If it sounds like a WRX check your spark plug wires, they are NOT in the right places..
