Troubleshooting Code 16, not usual cause...

[Dirty Harry]

So I just recently did a swap/conversion on this auto 96 EX. Now has a JDM F22A, 5spd. Used the boomslang fabrication OBD2a -> OBD1 conversion harness. Using PT3 ECU.

As you know, the CEL stays on while the pump primes for about 3 seconds... then it's supposed to turn off when the pump ceases priming. Without even trying to start (which of course it won't) my CEL stays on...when pulling codes, I get #16 (injector/circuit).

Here's what I've tested so far:

Main relay is good.

All fuses are good.

All resistors in resistor box are within spec.

Resistance of injectors are within spec.

There is continuity between yel/blk wire at main relay and yel/blk at resistor box plug.

There is continuity between red/blk wires at resistor box plug and their matching wires at the injector plugs.

There is continuity between individual injector wires and their respective pins at the ECU (A1/brn, A2/yel, A3/red, A5/blu).

Yel/blk wire at resistor box plug is hot when ign. switch is set to ON.

ECU pins A25 and B1 are also hot when ign. sw. is ON.

I really don't know what else to test, I went through the entire injector circuit... is there something else that would trip a code 16? First time in a long time I've had a real WTF like this...

EDIT: I can also read resistance of individual injectors by using ECU pins A1, 2, 3, and 5, and the red/blk wires for the resistor box plug. It's all there. What the fuck am I missing...

Nevermind, fixed it.

And it doesn't suprise me that nobody answered this

haha good job... what was the problem?

[Dirty Harry]

A few sensors that according to schematics, have nothing to do with the injector circuit. I actually wired in an OBD2a ECU and using a scan tool, found the real problems. After those were fixed the OBD1 ECU stopped throwing 16.
