Need Help Diagnosing Gtr Ecu

[JimX]

Ok I'm getting a bit sick of not knowing which part of my electrics is actually faulty, so I was wondering if someone could help me test my ECU. I'd like to take my ECU out and plug it into another GTR (32 or 33) and see if it does all the same crap, which is not prime the fuel pump and not get a spark and hence doesn't start at all. If it works, then obviously it must be in my loom or immobiliser or something.

Or if anyone can let me know of a way to test it for certain, then please let me know. Thanks!

You are welcome to try it on my car Jim, if you want to bring it to the hills area.

Just wanted to say an absolutely HUMUNGOUS THANK YOU to wrxhoon for helping me sort this out. Firstly my ECU wouldn't start his GTR, then to make sure nothing else was wrong we tested my car with his working ECU and it fired up easily. Now all I have to do is make sure the alternator isn't overcharging the battery so it doesn't fry the replacement.

Edit: New ECU going in car tonight after I pick it up!

Pleasure helping you out mate, i hope the new ECU works OK.

Put your multimeter on the battery when you have the car running at say 3-4000 rpm. You should see about 14 volt.
