I removed my 1990 964 C4 motor and transmission. Replaced clutch, cold air kit, plugs etc. Re-installed, all went smoothly. Hit the key and no start..cranks and cranks but start. after investigation.. no power at fuse 20 thru 23 and 30 thru 34.. I have checked and rechecked and it doesn't make sense to me what am I missing?

I just got a chance to look at the fuse box details. Fuses 20-23 are your head light high and low beams driver /pass side. Fuses 30-34 are your turn signals front and rear. This is not a factor with your no start issue. I would start by checking/replacing the DME/fuel pump relay Its # R41 in the fuse box. If that dose not work then you need to double check every connector you touched to be sure you did not cross anything when reinstalling the motor.
