Ecu Has No Signal Wtf Urgent Please Look, need help just 2 get my car running
hey peoples .
getting more and more frustrated daily .
i just completed a 4ac to 4age 16v conversion .
i got the wiring harness all connected and all the plugs in .
my delema is when i wired up the last pinout out (14pins) i can't get any signal from that side of the computer , its al dead , i checked if theres power from igntion goin 2 the ecu and there is , so my problem is y isnt there power leaving the ecu 2 the motor and gettin things going?
ive checked fuses etc etc .
can i have a blown ecu , but the ecu was completly running before , is it possible just 4 a ecu to f@$k up like that?
what checks can i do , or any ideas u can give me guys would be great
thanks 4 ur time again

you need to power up the big chunky orange wire in the loom. this runs the injectors and a few other things. it will be around where the battery is.
the ecu only switches grounds to the devices. and the big chunky wire supplys positive power to the devices. it is usually switched by the "efi main" relay. i just put a new relay in near the battery.
have a look here
the first box of wires is what you need to connect to make it work.
