I am trying to test if my maf is bad or my computer.

Could someone please remove their 91-94 s13 maf harness and tell me what resistance they are getting from the harness connector maf signal wire to ground, with the harness disconnected?

I am getting a little over 20k on my ohm meter.

The maf isn't sending any signal volts when I check with a push pin and volt meter while running. Wire is good, tested perfect continuity, no resistance from ecu connector to maf connector.

Now I just got to eliminate whether the computer or the maf is screwed. Thanks!

What makes you think the computer is bad? Did something get shorted out

Nah, just covering all my bases. Been chasing a big flooding issue

Never mind. New maf has proper signal. I just like to test everything instead of throwing parts at problems.

Hey your flooding issue, did you fix the problem with a new maf? My S13 is flooding with fuel, injectors are not leaking, somthing is telling my ecu to spray fuel and keep spraying
