Car Wont Start After Stock Ecu Put Back In

[errno]

Hey guys

Took out the powerFC I had in the car and put the stock ECU back in. Car started for about 1 second and then stopped. When I tried to start it again it cranks but doesn't fire up.

I had a look in the fuse box under the dash and the "aircon" (エアコン) 10A fuse was blown, I replaced this, tried to start and the same thing happened - it started for 1-2 seconds then died, after that it sounds like it is turning over but wont start up.

No other fuses I can see are blown at all.

Only mods are the pod filter and FMIC, nothing else has changed except for me taking the powerfc out and putting the stock ecu back.

what AFM are you using

what AFM are you using

stock AFM - sorry I forgot to mention, its a S2 r33 gtst

any ideas what that fuse actually hooks up with so I can check it? The climate control unit comes on when switched to ACC and when i press A/C I can hear the relay in the engine compartment click but nothing else happens. Hard to imagine anything wouldve fried when all that changed was the ecu

Try the power fc again then try the stock ecu again. Might not be 100% plugged in at the blue plug

was the battery disconnected when you swapped ECUs?

[errno]

Yep disconnected battery first, I'll try the powerfc again

Yeah I would be checking to make sure that blue plug is in tight can cause it to have your symptoms if it isnt.

was it the original ecu for the car or a replacement one you bought?

if so it might be for a series 1 auto or something a bit different that is pissing it off...

Its weird that your AC fuse is popping. Ensure your AC is off before you try start it up. Is this the stock ECU from YOUR car or did you buy it? I'm sure if you check up the numbers on the ECU against a R33 Series 2 Manual GTST on the net you can confirm if the ECU is the right one for your car.

Yep, my original ecu

i had an issue when i put an emanage ultimate into a mates 33. it wouldn't start. put the stock ecu back in and it would start. turns out it was the loom not quite plugging in right (dispite looking like it was it, some pins just weren't making contact). i pushed on the plug a bit and it started first go

put the powerFC back in and it no longer blows that fuse, car started a bit rough first time

nfi whats going on unless its a stuffed stock ecu

I had this same problem, just because the bolt is wound right in and the plugs looks ok doesn't mean it actually is in all the way.
