Check engine light after A/T to manual swapping

Hi. Sorry but further diagnostics is necessary to find out what the specific failure is. When you turn the ignition to the run position. The ECU relay should close and send power to the ECU. You bypassed the circuit and manually closed the relay yourself. So you know that the ECU circuit is fine but the ignition circuit is not working. Identify the two pins used to energize the relay and find out if you are missing power or ground while the key is on. Clamp the test light lead to the battery negative terminal to test for power and clamp to the battery positive terminal to test for ground. Please let me know what you find and if I can be of any more assistance. Good Luck.

Different engine means a different ECU and a different wiring harness from the original in the car not to mention other items. (Never a good idea to try and fit a different engine from the original given the complex electronics). You need to plan the feasibility of these kinds of engine swaps before you decide on doing it. You will now need to employ a professional to work out the wiring but you might have a problem finding a competent mechanic willing to take on the task which will be complex and time consuming.

asuming both engines were the same capacity 1.6?1.4? and all parts from first engine were used like air intake/airflow meter etc then original ecu can be used,if all the cavelier parts were used then ecu from donor could be kept with wiring loom etc.poor running could the ecu be running "get u home"mode needs reseting then codes read.if wiring loom from corsa kept are all the sensor wires connected to correct parts of engine?oil temp/water temp/flywheel sensor/oxygen sensor/etc even speedometer all needed for ecu to adj correct fuel air mix for smooth running.was the donor engine running ok b4 its transfer?if u havent already go join an online corsa.org type website where multiple vauxhall experts will be found to help

Are you trying to use your harness and ecu from the existing v6? Please say no cuz the ecu for a v6 will not work well for the v8. I would suggest getting the ecu harness from the vette you got the motor from. GL.

You can find free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. Year , make , model an engine size . Under system click on brakes .under subsystem brake control will show on it's own . Click the search button .

You might want to check the ECU of the engine that u swapped it to. Because the original ecu is only for the 1.4L non vtec!!!

Wiring faulty, sensor not connected or mismatch, the ECU will not operate normally until it get all required input from the various sensor.

make sure all grounds are connected. usually it is something easy or stupid.it should work.an obd-II scan may help pinpoint the problem.
