Default my audi 2.8v6 doesnt havea spark signal or a fuel injection pulse? can anyone help

i have a late 1992 audi 90 quattro with one of the first v6 2.8 engines in it. the car is getting no ecm signal to fire the coil and no signal to the injectors either! i have checked the cam sensor, engine speed sensor, crank sensor, the powerstage, the teeth on the flywheel,and i have replaced the ecm just to see if it was bad. i have power to the coil i just have no signal from the computer to coil or the injectors, the fuel relay works and there is gas to the rail. the computer still doesnt bring up any trouble code! does anyone know if there is a inline fuse between ecm and these components somewhere in the dash hidden. does anyone have any ideas? much appreciated, Beau

Default Sounds like a bad or disconnected ECU?

Are you able to get the DTC codes off the ECU?

Default Re: Sounds like a bad or disconnected ECU?

no i am not able to get any it just say there arent any. i have replaced the ecu and there is no change to test the ecu i disconnected the engine speed sensor and then it brought up the engine speed sensor code so it seems to be working
something in the wiring is screwed i wondered if there was a fuse in between the ecm and the coil and the ecm and the fuel injecters
