I have this issue I can seem to figure out. Z32 with Rb26/ z32 maf sensors/stock turbos/750cc inj/jim wolf ecu. Everything else factory. A few months ago this issue came about, basically when I turn ignition to ON the fuel pump would prime continuously, I swapped out the relay by the kick panel and that solved that issue. But even after I did that car would not start, it would flood, sometimes I could even hear injectors clicking with the key on the ON position while I stood by engine. Took me a while to figure out that If I disconnected the maf sensors car would fire right up. But as soon as I connect them back car dies I instantly. When cold, car will sometimes start with both connected, but as It warms up it will eventually die. It will idle fine for as long as I leave it on if both maf sensors are disconnected sometimes with one too. The other thing I found out is that it will not start if the aac valve is disconnected, If I start it and disconnect it car will die instantly. When it is plugged back in with the key on the ON position the fuel pump primes, im not really sure why. Also, when I is unplugged and key in turned to ON it will prime for like 1 or 2 secs, instead of the 5 or so. I did find that I had some stripped wires to where wire come out into firewall (probably the damn mice, I found a bunch of mouse shit in different parts of engine bay, I live way out in the woods)
Anyhow, I have replaced wires to both mafs with new wiring and just about all the wires that go from ecu to sensors/relay box. I have tried 3 different ECUs with same exact results. All 3 ECUs give me code 12. I have also tried brand new MAF sensors with same results. Starting to get pretty frustrated.
Any suggestions on what to try next or has anyone had a similar issue? Any help would be greatly appreciated.
Thanks in advanced!
