I just had the same thing happening to me. I got my mechanic to pull the starter out & he cleaned it all up & straightened the brushes have not had a problem since.

Generally in days gone by I would have just pulled the offending starter and replaced the brushes or whatever may have needed attention, but with passing years I would probably get someone to pull it for me (STEADY NOW!). ;ay
I know I'm getting away from the original theme, but I recently had cause to repair my alternator which as it turned out had blown every diode. All it cost was 15 minutes of my time and $40.00US for an 80 amp upgrade kit I bought from the States. Admittedly I wasn't about to discard the casing as I'd already spent hours hand polishing it. Here I go being anal retentive again...Oh well.:mmm

Got a brand new starter and solenoid from rare spares for $200 and guess what... it still didn't start.
I connected it direct and it started to crank, so it's dodgy wireing somwhere...
So I started to look under the dash, looked at the immobiliser somone had put a few years ago.
There is a wire that you unplug to activate the immobiliser which I KNOW used to work coz I used it. Anyway, I was still at a loss so I unplugged it and tried to start the car, it started! So then I plugged the wire- it started again! So I thought, ok whatever, now for some reason the immobiliser doesnt work.
Went for a drive (of course) and I noticed the needle of my aftermarket tacho, that I installed was very straight whereas previously it had been VERY wobbly.
A few days of this, I noticed the tacho being wobbly again, and when I went to start it the next time, it again wouldnt start. But this time its not as tragic, a few turns of the key and it starts up.
And thats how it is now.
So:
1) Imobiliser no long imobilises
2) tacho wobbles (its electronic)
3) cranks after a few turns of the key (very random)
So in my humble opinion, either the imobiliser is really playing up or I have a grounding problem.
What do yall think?
thanks,
Adam

Ummmmm......I probably shoulda' mentioned it but always test a starter out of the car before buying another one!
A lot of troubles can be traced back to immobilisers (which we didn't know you had). Usually a grounding problem, which I had in my Patrol.
Anything electrical is a nightmare.
Adam:
U see, thats why I'm an idiot...
I did "test" it outa the car but... I obviously connected the wrong terminals etc etc.
hmm, well the new one sounds and goes better tho.

Brutus:
One of the easiest kill switches to make is to wire one of the tacho leads to earth through a switch.... I'm just wondering if you have a bad earth in there somewhere.
