Hey guys,

I've had this intermittent ignition problem for a while now but its started to get a bit worse.

Basically when I turn the car to ignition, sometimes I'll get that high speed tick like the battery's flat, and the lights will be really dim and flickering on the instrument cluster - other times everything is solidly illuminated and she starts perfectly.

The other issue that I've got, which has happened intermittently for about 3 months is I will turn the key to turn the engine over and I will get this staggered crunch/clap sound coming from under the bonnet. It only does this sometimes and the rest of the time it operates with no complaining whatsoever. Sometimes I'll also turn the key and have nothing happen for about 3-5 seconds and then she will fire up (with or without the crunching).

I've been told that its the starter motor but I don't think this would be affecting the voltage to the instrument cluster etc - is a starter motor likely do affect system voltage as well as the general starting of the car?

Your battery terminals, are they clean? It could be the starter but try a different battery and replace the terminals first. Check the earth clamp to the body and the engine too, clean everything with a wire brush.

Sounds like a loose earth maybe, check the battery terminals and stater motor wiring, hopefully its nothing more!

Yeah man, gonna just have my mechanic suss it on Friday. I'll come back with the cause on Monday.

    • Bummer...yeah i "need" something to "ease" up the work and for my driving it would be enough.    Iam counting the tune "without" turbo. I do not mean "cheap" like something from Temu around 200 USD, "Cheap" is something around 1000 USD? 
    • Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.
    • So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!
    • OK, few more things sorted and it is ready for a shakedown on 10-Oct, with one weird thing. Changed the run in oil and filter for the good stuff. 8l came out, about 8.5 went in with filter so that looks all good. Changed the starter (again), this time for a brand new one, works good. Interesting that the Taaaarks one is shorter than factory but spins harder, I guess electronics have moved on a little in the last 30 years. Will be nice to have a bit of extra space under there. Put the timing cover back on, and noted where the cam gears were set as a record.  Will need to double check the timing but it is pretty close. Also put the coil pack cover and intake snorkel back on. Exhaust Inlet Changed the water out for coolant, bled up nicely. Removed the rear brake pads (well worn factory sumitomo ones!), gave the hardware a good clean and reassembled. I've put bendix XP on the back again because the price is excellent at $150 a set and they worked well on the V37. Front pads have plenty so no issue there
