I'm wiring up a new ECU to my original harness, but AFAIK I have left all the original wiring intact (bar removing the engine loom and ecu)
Now, I've wired up the new ecu, and I turn the key to 'On' and when I turn it back, the ignition stays on until I disconnect the battery.
I'm guessing this is a relay not clicking off.
Anyone have any ideas? I'm gonna get the car wiring diagrams out tomoz nite and do some tracing, but I'm just wondering if anybody else has had this problem?
Could it be my Immobisiler? (AFAIK I have by-passed the fuel cut off for it)
