hi, i dont know whether you guys have ever faced this - the "new" rebuilt engine is back in the car but when i turn the ignition key the rpm/tachometer goes crazy and then stablizes at approx 5000 rpm

the ignition relay "E" in the fuse box makes a really fast huming noise - not like on the other 900c turbo ive got

the car will turn over on the starter - and the noice from the relay stops when i do so

any suggestions?

thanks
Rob

The rev counter takes is signal from the ignition amp attached to the nearside inner wing, which in turn gets its signal from the hall effect unit in the dizzy. I would check connections between these two units initially.

I assume nothing was touched at the ECU in the drivers footwell?

also check the coil, a bad wire here might cause trouble too, ask me how I know... :(
