My Computer Shat Itself

[Space Goat]

hi... im in the middle of wiring up my car and i screwed up... its a rb25det neo... i went to start the car... fuel pump charged up, starter motor cranked... and cranking and cranking... but no start... ive checked my spark and my injector wiring and its all correct... i then went to the computer and it smelt like the smell you dont like to smell near electrics... i opened it up and i found a diode or resistor to be had it... ive got another computer on the way but i want to know what caused it to let go... the number of the diode/resistor on the computer chip is D620... could anybody tell me what that diode is... or where can i get an electric diagram of the actual computer... if i worked out what pin fed this diode i could work out where i went wrong by using the ecu pinout... i cannot follow it back on the card because the card is multi layered or something like that....

thanks for your help

dude, you didnt end up use a relay for the fuel pump did you? BOOOM HEADSHOT.......too much current going to the ECU because of that relay not there.....

did you change coilpacks from standard to an external pack? if you did then that could be the problem. my mate did it with his. put some MSD coils in and got the wrong ones and fried his ECU.

cubes had his power fc fixed by force electronics for around $150.

Providing your loom came with the eccs and ign relays which is should have, then you should have a spare green relay left over near the kick panel.

Use that, if its still there.

Otherwise go the wreckers and grab another one off a r31.

thanks for that ill do that...

does anyone know where i could find a electrical diagram for the actual computer or tell me what the diode # D620 connects directly to
