perplexing issue

chassis is an 89 GTUs however entire electrical system is S4

- Vert rear chassis harness
- auto front chassis harness
- turbo engine harness
- S4 turbo engine

Ive had the engine running with a vert front chassis harness until some wires fried and we replaced it. timing is dead on

I tested spark, thats good
Fuel pump is operating yet upon pulling the plugs they smell like gas but aren't drenched like what you would expect from trying to start

The engine isnt even trying to start... at all

Ive never worked with an Auto front harness before and have a hunch thats whats whats causing it to not start, however with fuel and spark you would assume it should start.

any help is appreciated
