S13 ka-t. Car wont stay running

[thekyroshon]

Ok to start out I have a ka24det. The motor has ran good ever since I've had it. One day it just took a shit and wouldn't stay running. After I started it up. I've changed maf 5 times to see if it's the problem but it's not. I unplug the maf the car will idle and rev up to 3 grand that's it. If I plug it in the car bogs and dies when plugged in. It starts and idles for 4 seconds the dies. Can't give it any gas. No vacuum leaks that I found. Maf works on other cars. Someone help.

Is your fuel pump dying? Might be fine when you start due the the lesser pressure but cant keep up to the idle? My ka-t had a similar sounding problem and ended up being the pump

Car runs and idles good and says running with maf unplugged though.

I guess you have to start tracing wires and see if you have a short somewhere, or check and make sure all your plugs are plugged in all the way and not loose, i'm out of ideas... Maybe wait and see if anyone else chimes in

Try running a secondary ground for the MAFS directly to the chassis.
