Strange ignition problem Options

[Quidam]

So I love my new GT4, far more than I thought I would when I first bought it. No longer a daily driver (as my first intention) it now shares duties evenly with my beloved MX5

But this morning when I tried to fire the car up, all I got was a single "clump" noise. First thought, maybe the battery is almost dead -but the battery was fine. (all electrics running without issue) Tried again and it fired up fine. So I killed the engine and tried again, same issue -a single little "clump" then nothing. And again and again. Finally it decided to fire up.

Strange thing is when it does ignite, it does it brilliantly without any struggle or delay.

I realise with every question like this I demonstrate my ignorance of all things mechanical, but that's why I'm asking -I really haven't a clue as to what this could be. Spark Plugs? I have dropped the car off this morning at my local mechanics and have asked them to investigate, but I'm betting it probably won't even fail for them (Murphy's Law) and am interested in anyones thoughts

Cheers

That said, it could also be a combination of it. Sometimes a new battery will make a starter solenoid problem disappear (when it's on the border of working/not working) because it's got just a little more juice to it to jump the gap that exists from worn contacts in the solenoid. But after a while, it won't have its initial high charge, and the problem will return.

With that logic, it's possible that it's still your starter solenoid, assuming delusionz's theory that your alarm may be sucking up too much juice holds true. The alarm system will be pulling just enough power to set your battery below the level it needs to be at to push through the worn starter solenoid contacts.

Just throwing out other possibilities
