I got a 97 S14 ka with s14 harness and ecu in my 90 s13 chassis.
Motor has spark, and fuel but the injectors do not fire.
Any ideas?

Using 90 sohc trans also.
Thanks.

You're kind of contradicting yourself. Can you be more specific? How do you have fuel but your injectors aren't firing? You wouldn't have fuel if your injectors aren't firing. Clarify a bit for me and everyone what exactly you mean so people are more inclined to help you out

Ummmmm did you notch the bellhousing to mount that sensor that reads off the flywheel?

How do you know your injectors aren't firing?

Sorry, i took the fuel line off of the fuel rail, and fuel comes out, i disconnect the fuel rail, crank it and the injectors do not spray. The car will start with starting fluid though.

The crank sensor doesn't do anything, only detects misfires. The car will start with starting fluid.

I took the fuel line off of the fuel rail and fuel spills out, i took the fuel rail off and tried cranking it and the injectors do not spray

check your injector wires to your ecu. Maybe they aren't wired properly or in the wrong spot, check your grounds as well.

To me:
I would check voltage and resistance at the injectors to make sure they're good.
i would also check voltage at the plugs to make sure its not that section of the harness
also check to make sure the ecu is sending power out of the injector wires. could be an ecu issue. You have to check all of those things to determine what exactly it is though. it just takes a little elbow grease and some time.

Here are a couple threads for you to look through that may help you. I would just search and read up.
