    Default 348 start issue

    From cold the car starts fine, however once warm the car doesnt like starting, it will either struggle to start or chug and not start
    If i hook a jump starter to the battery terminal in the engine bay (batterys located upfront) the car starts just fine.


    Ive ordered a new battery incase thats the issue but the fact the car starts fine first thing in the morning has me wondering if this isnt the issue?

    Edit: probably not what I just wrote if it starts fine on jump leads.

    Ive read mikes suggestion on the wiring mod so thanks for that, im just confused
    As to why it would start fine with a jumper pack, then again if its a dud battery i would have thought id have issues starting the car all the time

    The cars recently come out of a long hibernation

    My post was about the flywheel maybe needing repacking with grease. If there’s not enough grease in there it can get out of balance and so cause starting issues when the engine is warm as the grease runs to the bottom of the flywheel. Not sure it’d explain why it starts ok with a jumper pack unless the pack provides more power than the battery and so can overcomes the balance issue.

    My understanding of the flywheel issue is the grease thins out and allows the components inside to rattle around which is transmitted through the engine and is picked up by the crank sensors confusing the ECUs timing capability. Ive never heard of this in any other marque but it seems to be true in this instance going on what Ive read.

    I think the starter relay mod is a good idea anyway knowing these cars suffer from this issue. For what it costs and the ease to do it its a no brainer. You can make it look like a factory fit. Maybe your battery is past its best if its been stood up a while.

    My mistake I knew it was due to the grease thining when hot causing an inbalance/‘wobble’. I didn’t know it was confusing the the ECU and thought it was just the inbalance itself that was the issue. Anyway, a car that’s been stored for years and possibly not run, it’s entirely possible the flywheel needs repacking. It’s a diy job, think there’s a vid from MadDog on how to do it......
