You either have a fucked up harness or don't have things plugged in or fucked your own harness up. When you're doing a wiring job you only have to extend the mafs, don't have to touch the CAS wiring, ETC wiring etc... so these are what you need to do:
1. Check ECU plug for being warped
2. Open ECU check if plug leads have snapped.
3. Unplug and Replug all connections. You might also have a key grounds missing.
4. Test somone elses ECU or have your vendor replace it free of charge.
5. Have harness examined (by me
(me "soliciting"))
