Starter Motor

In need of some advice. I have intermittent weak start, sometimes feels not even going to crank. Has new battery & new alternator. I've cleaned connections to starter as best I could, I've whacked it a few times make sure its not stuck. Like I said intermittent but lately getting bad. How can I tell if starter or solenoid or just replace both? starter comes with new solenoid right?
And if so, which is best to go with? I've vaguely looked into removing it and that 2nd bolt is a pain to get to.....
thanks

phil

Have you checked/cleaned/tightened all connections?
Battery->solenoid->starter motor->chassis ground->chassis ground->battery?
Have you made sure your battery is fully charged?

If yes to all of the above and it's intermittent slow cranking it's probably the starter motor.
If it's intermittent no crank it might be the solenoid.

For replacement for a V8 starter I highly recommend a gear reduction Denso starter from Britishstarters.com
Starters for a Rover V8 come with a solenoid.
Alternatively you could have yours rebuilt.

I assume the battery is charged. Its less then a year old. And not too long ago I cleaned connections to starter as best I could considering its location. Even changed ground strap to engine block since I suspect some bad grounds. I'll have to get in there again and clean house..... its definitely intermittent and yesterday noticed my temp gauge swaying around while driving. Last time it did that I replaced the alternator which was shot..... so I don't know if I have an electrical issue or if it is starter with other issues.....

That Denso starter is pricey but looks solid....

Thanks for great info

Original starter? How many miles? Is it soaked in oil from leaking rocker covers/intake/heads? Clean connections at new battery posts, down the ground to the transfer case and frame? What's the voltage of the battery at rest and with the engine running?
You mentioned intermittent weak start. Cold engine? Hot Engine?
What other diagnostic efforts have you made?
"Cleaned the connections to the starter as best as I could"- removed the battery cable and cleaned the surfaces that contact the stud?
Your description indicates that when the potential no start crops up, it still cranks just very slowly so I'm leaning towards an inability for the current to get to the windings on the starter armature. Could be power to the starter- battery cables/grounds or through the starter- solenoid/armature/ground path, but not likely the trigger wire from the relay to the solenoid.
True, the gear reduction starter is not cheap but I have one on my 4.6 Disco I trail rig and it spends time caked in mud, drowned in rivers and otherwise used with enthusiasm. I dont reach for the key wondering if it's going to restart.

thought of another diagnostic: have a good quality set of jumper cables handy and the next time the event shows up, connect the jumper cable from the battery negative to a solid connection at the engine Ie: the alternator mounting, or a engine lifting hook and see if that has an effect on cranking.

I'm sure it is original starter. Motor has about 96K. I did remove connections to starter, ran some steel wool, replaced nuts where I could, including to grounds. I replaced ground belt to transfer case.
The intermittent weak start can be hot or cold, but seems more often when motor still hot. I would guess its starter considering age but other day temp gauge was rocking back & forth which in past sign of low voltage..... I have to get a new voltmeter old got crushed.... I like the idea of hooking cables from battery to frame.... wonder if all this has something to do with recent TPS cable going.... thanks

I've even used mine to move the vehicle off the road when I ran out of gas on an incline. Having a manual gearbox helps.
