After 3 years of almost trouble-fee motoring my '31 has just acquired an issue with it cranking but not starting intermittently. A problem which has been bought up many times before on the forum, now it has happened to me. So a brief run down of what has happened since it occurred / what has been done so far to try & rectify:
- Fueled up 40 or so liters of BP 98 before an hour long trip - Car starts & runs completely normal upon leaving - Get to destination, car sits for 30-60 minutes - Before having to quickly move it, turn key car starts immediate however not bursting into life as usual - Park car up leave it overnight, restart the next day & it's cranking but not starting - Can be revved continually however as soon as RPM drop car stalls - "Engine electrical system" will display upon stalling ONLY if you attempt to keep the revs up
Now I should mention that the car has a 12 month old new OEM fuel pump ECU, 6 month old leads, 12 month old fuel pump (now changed), 18 month old distributor caps & rotor buttons, 2 year old iridium plugs (now changed), Denso 02 sensors a few years old, OEM 200,000 km service 8 months ago etc.
So far I have replaced the following parts since the issue occurred: - New Walbro GSS342 fuel pump - 2 leaking caps in Mine's ECU replaced (rest will be replaced once I receive the caps in the mail) - Close to new OEM coil packs - New standard series NGK plugs - Cleaned IACV & fitted new bearings
Since this, the car can now keep idle & run if you give it a rev or two straight after start-up but will not keep idle without the assistance. And it will drive like normal once out on the road. Disconnecting the AFM shows no difference in idle etc. I have yet to change the fuel filter, however will be in the next coming days.
I will be picking up a spare AFM & igniters tonight also just to rule them out if they aren't part of the problem. Should have them as spares regardless.
So coincidentally the only change to the car was the new fuel, prior to this the car was in perfect running order. I only changed the oil a week before, other than that no changes.
If I have left anything out I will further add to it, in the meantime I look forward to reading some opinions.
