Ok here's the run down I had a 95 sc400 with a w58 swap was like that when I bought it recently just was in a accident.....so I bought a 92 sc400 with a blown engine...
I swapped everything over engine and transmission and harness...degreased the engine and washed dried for a week
Now everything is in the 92 and it will crank but won't start has no spark its receiving fuel
I checked for power at the the relay and the fuse at the igniters I get 5v and the fuse I get the 12.5v idk if this is correct
I check the wiring to the crank sensor I get a ground and when it's cranked i get .5v
Battery is charged
I've swapped in ecu, crank sensor, igniters, maf, relays and fuses nothing this is making me crazy I don't get it
When I crank I have no rpm on the dash

I noticed that in the relay box in the front that my 95 didn't have a ignition relay but the 92 does do I have to swap the forward harness also?
Is there some sort of security I have to disable or something with the swap like a safety switch....I'm lost if anyone has any ideas please let me know

No one has any ideas or does some one have a wiring diagram of the ignition system

Ouch, the issue you're having is the 95 harness in the 92. Pull the 95 harness and use the 92 harness along with ECU. The pins and the harness is different. However, the long blocks are the same (sans the cold start injector which you won't need in NV).

Son of a ..... Can I use the 95 ecu and swap the front loom with relay box....the 92 harness was in bad shape hacked up
