All the injector wires are connected in the ECU. If one is inadvertently grounded they all are. If the +12 gets inadvertently connected to the injector ground the ECU is instant toast. No fuse protection here.

Dennis,
And I still can't type on this Windows 8 Phone!

That would have to be that the injectors are being held open continuously ..
due to ...
bad ecu. I have seen it on a 1.9 wbxr before.
Since the ecu is the only thing that triggers the injectors in
milliseconds of open time ....
it pretty much has to be the ecu.

'if' there was just one wire by which the ecu batch fires theinjectors ..
that wire being grounded could cause it too.
But it's 4 separatewires from ecuto injectors. It's not likely all 4
wires would be shorted to ground.
Bad ecu, mostlikely.
One of these days let's have a good , and simple , discussion of how
Digijet ( or Digifant ) basicaly works.
It's pretty simple actually. Understanding that could help a lot in
trouble shooting ...especically for something like a 'no-start' or this
situation too.
