Whats up guys.
I've recently decided to do an sr20det swap on my 240sx s13 that was automatic. but ive run into some trouble.
simply put the car just cranks and cranks with little backfire. ive timed the car multiple times but with no luck. same thing happens.
ive check spark and it is blue on all spark plugs. it smells of fuel and will flood the engine.
When i was doing the swap i messed up on the wiring on the passenger side behind the headlight but, I am assured that it is all fixed.
The only thing i could think it would be is the cas. as it has a bend on the disc but idk if that is normal or not.
Im gonna buy a new wiring harness just from wiring specialties but i honestly dont think it has to do with that area of wiring.

my real question is would a bend in the CAS completely disable the engine to not start at all? Some times when i turn the cas a little it will sputter but i havent heard the engine start.

anything helps. Will upload some pics of the cas and the engine. maybe make a small video on youtube this weekend to show whats happening and get some better knowledge of my situation to you guys..
