My R34 Gtr Won't Turn Over

[mdang]

Need help from all. As per the topic my GTR won't turn over. Just to give you a background on what has happened. Playing with the GPS at night so i turned on the two reading lights at the front and forgot to turn them off. After I closed up i always chuck my CTEK trickle charger on to keep my battery going when i don't drive during the week. GTR is only for the weekend drives. So i when i go to start on the Saturday night discovered battery was drained and found out the lights were on. So i had to jump start however it wouldn't turn over. seems like its not getting sparks or no fuel is getting injected. I have checked the fuel pump and its pumping fuel. Looked at error codes and i get code 55 - No Malfunction. I'm lost as what the problem is. Thanks in advance for the help!!!

how long did u have the booster cable connected while trying to jump start it.. if your battery is really flat, it still may have trouble starting.. try swapping in another battery.. or get a multimeter out to check voltage.. sounds like battery

swapped batteries, started first go

OK updates - battery is pumping out 12.8V. Tried starting it and it started however only for 2secs then cut out. Tried starting it again no good. Fuel pump issue ?

before you go around diagnosing everything just swap the battery with a working one and see how it goes

should read around 13-14v on idle
