Car: ca18det swapped 93 s13 convertible

Post

Ok so here's the deal I just recently finished cleaning up and redoing my ca18det swap into a s13 vert. Good every thing hooked up and ready to go... And it won't start! Just cranks and cranks and cranks, It's getting fuel and spark and has good compression. I did some reading and I figured I'd do a ecu diagnostic, and I threw a cas code.. I pulled it out span the lobe and the injectors clicked. So it should mean its working? So I pulled the coilpacks and double checked for spark.. Found out the coilpacks to cylinders 2 and 3
would spark once then wouldn't spark again, while cylinders 1 and 4 are sparking constantly. I have no idea what the hell is going on and would
appreciate any help

Oh! Idk if its any help but before I pulled the motor to clean everything up I kept blowing alt fuses, not knowing that my alternator was grounding out on its self. It stopped running at the same time I blew the first one.
:confused: :confused: :confused:

I'll be moving this to where it can get more attention. On to the CA forum and BTW, you have a wiring issue or a blown ecu. Also could very well have a faulty CAS, but the way you are testing the CAS is not conclusive.

Thank you! I did replace the cas and ignitor and still no luck so I figured it was one of those two :/

I'll bet the grounded alternator damaged the ECU. Either that or you have a wiring issue.

If when you spin the CAS your injectors cycle and you throw spark, I'm not sure why the ECU is bad. I have a terrible suspicion, though.

Now you have never heard this motor run?
