Hi guys.
After many hours trying to figure this problem out, ive gotten no where!
My very recently purchased R32 skyline is having what i believe is an ignition issue.
Firstly within a couple of hours of buying the car, i was reading to overtake when the car started to go sluggish. no throttle, went into 4th, nothing, went into neutral and dash lights came on and engine stopped.Tried to restart, nothing, tried again nothing. cranked it again and it bursts into life. Drove another 100km and no further problems.
Then next day i drive it around, town etc, out to work, park up. Come back after work, reversing, think i stall as car dies, wont start. Keep turning it on/off and cranking and wont start. Eventually after playing with the coil-packs, ignitor and wiring around that area it starts.
Since then it has died while idling on the turbo timer, driving in a 50km area, refused to start multiple times, but has run great when its gotten going. To start it seemed to involve moving the connecters around near the coilpack and ignitor pack? but when moving those same wires while the car is going hasnt caused it to then stop (which would be more movement then it would possibly get while driving too i suspect)
I can hear it cranking, fuel pump start, and fuel pressure at the fpr, also oil pressure begins to build if continuously cranked.
The times it has died, i have wriggled the wires around the coilpack, ignitor etc and its started, but then when it running, wriggling the same
area doesnt make it die! Apparently the last owner has no record of this fault, and thinks it has come around since it had an AA inspection where
the inspector removed the coil pack to get to the spark plugs for a compression test.
Car is a R32, with RB25DET S1 conversion with wasted spark (in the worst place i would think it could be put) and chipped ecu of unknown kind, or type.
Checked battery voltage, is sitting around 11.95v on battery and around 9.5, 10v when cranking
I was looking at doing the ecu diagnostic but with it being a suspected chipped ecu, and not know much about it i dont want to cause a problem like
fry the chip/ecu etc.
Any help, question, or suggestions on what i should try next would be great!
(Though im already thinking a rewiring of the ignitor and coil packs might be the way forward as it appears that the AA inspection has broken a couple of the little troublesome clips in use. Local Auto electricians need the money too haha!)
Thanks for your time!
