Hello,
So I bought a relatively stock R34 GTR and after 500kms (all was working fine) the engine just shutdown on the highway.
The engine is cranking but refuse to start again.
So in the correct order, I checked using the supplement service manual:
-no engine light at any moment
-fuel pump (I can hear it when I switch on the key and the fuel pipe gets hard)
-checked all the fuses next to the throttle pedal and also in the engine bay
-self diagnostic give me error 55 (so no malfunction)
-I have 12V to the coil ignition on the power pin of this coil
-I don't have an oscilloscope however when cranking the engine I must see like 0.06V to 0.09V on the command of the coil ignition using a multimeter but I got 0v on each command of the spark plug
-wiring of the ignition coil is okay (continuity test)
-There was an aftermarket ignition control box (adic siccle advanced ignition control) connected to the ECM; so I removed it however after doing so I got error 20 ? (the orignal hairness seems to be intact !)
-I open the ECM but didn't find anything bad (bad soldering, blow components ...)
So this investigation supposed that the ECM is not working properly ?!
Question :
-what is error code 20 ?
-if the ECM is working fine; what are the causes that avoid it to command the ignition coils ?
There is also an aftermarket alarm I normally desarm it (using the key fob) code alarm PF7600 I don't think there is a relation to my problem but I mention this.
Thanks for any hint
