Afternoon all.
Codger junior is carrying out a body shell transplant on his Nissan Silvia (1990's vintage) and has hit a snag of an electrical nature.
As it isn't a Fiat I can't put the question in the right place, but this is more of a general question anyway, so here goes.
He has transplanted the engine, gearbox, and wiring loom from one car to another, and the engine will not fire. We have a spark, and we have fuel, but the voltage at the injectors is only about 5v.
The "body" wiring loom cam with the shell that he is transplanting in to and has been hacked about a bit.
The ECU is no connected to anything metal other than via the wiring loom.
I have a shot in the dark feeling that there could be a poor or non-existent earth somewhere. So here is the general question - If I connect one of the ecu brackets to an earth by means of a separate lead, so that I know it has an earth, could I do any harm to the ECU?
Any other suggestions gratefully received as at this rate I am not going to get my drive back for the foreseeable...
