For the last week or so it's been struggling to crank over, Sounded like a flat battery so I put the trickle charger on it on xmas eve and it started no problems.

mid week it started to struggle again, worked fine NYE and then finally went to start it yesterday and it has gotten to a point where it it cranked but struggled just like a flat battery would and wouldn't start.

Put the trickle on it again, also tried a jump starter pack and now it wont even produce the click that even a flat battery would normally do. Put a multimetre on it and its reading a consistent 12.4V even when trying to turn it over. The lights, indicators, radio and air con work as normal but now there be nothing when trying to start it..

all the normal lights come on when the acc is turned on but when trying to start the cat light comes on. but I'm not 100% if this normally flashes when trying start..

The light between the oil and battery on the right of the rev counter.

The battery is a little over 12 months old

The starter motor was replaced with a 34 neo one about 2 years ago

any possible avenues anyone suggest to explore?

cheers!

Do you have access to another battery to try? Just to rule that out. I had a similar experience years ago on an old Mazda that ended up being a starter motor fault. I kept throwing bigger batteries at it until truck batteries wouldn't turn it over anymore. Starter was drawing too much power.

I had a similar issue with mine when I had no license. Week by week it got harder to start until one day fresh off the charger it wouldn't crank the car over at all. I believe one or more of the cells were failing.

Like the others said test with another battery and replace if necessary

Get your battery tested at any battery world or autoelec shop. They will be able to do a load test and tell you if its OK.

Clean terminals and install new or reinstall.

Check your earth strap to chassis and then check earth strap to the motor. Easy way to check is to use a jumper lead and go from the chassis to the motor - make sure they are both good solid connections with no insulators like gaskets etc. The lifting ring or exhaust mani is good .

Check your leads to the starter motor, undo and clean then redo. If you cannot here any sound from the starter then its the solenoid not throwing out. If you here a click/clunk then the solenoid is fine and your starter motor is probably toast.

    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
