Finished fitting the engine last Friday. Fired it up and it started immediately and ran for about 15 minutes untill it was warm at which point we switched off the engine. Checked all the fluid levels and fired it up again. Within 30 seconds we noticed smoke coming out of the ECU and then the engine stopped running.
Turned everything off and pulled the neg wire of the battery. Opened the ECU and found that a resistor was badly burned (R420) and a transistor (T450) was burnt so badly it had seperated from the board. Bugger
Checked the various connections and everything appeared to be fine although there were a couple of cut wires that may possibly have earthed to the inner wing but we weren't sure.
Managed to get hold of another ECU and tried it today. Plugged it in, turned the ignition key, fuel pump primes for about 5 seconds and 10 or 15 seconds later the same resistor (R420) starts to smoke. Checked all the pin outs on the ECU and everything looks fine.
Has anybody experienced this before and if so how can you tell me how you fixed it please ?
