I have a 97 vr that sometimes wont start. Central locking operates fine, open the door put the key in turn key and engine roars into life..........OR........ turn the key and nothing..... not even a click, dash lights come on its just a lottery if it starts :angry: :angry: :angry:

Sounds like the starter or solenoid?!

sounds like transponder problem to me if you have one fitted. what model have you got. some one will proberly tell you to change the ECU relay. :grin: :grin: :grin:

Hmm good point, if theres no click then it could be the transponder, but yeah my money is on the ECU relay! :grin: :grin: :lipsrsealed:

This is where I would start as well.

Starter solenoid or ignition switch if it's all fine except for the starter.
Sounds more igntion switch based if it's very random though.

if it does it again, try jumping red/black wire terminal on starter with 12v direct frombattery. if that works take p[lug off ignition switch and jump red wire to red/black wire. if that works its the ignition switch, if not its the wiring. the factory fitted and some aftermarket alarms are spliced into the red/black wire so if fitted that could be the cause.
id go with ignition switch though :)

I have endured the same for some time now, stripped the starter motor down and the solenoid piston was rusted.
If the piston doesn't move far enough, then it won't 1.) engage gear with flywheel, and 2.) create contact to allow the motor to spin.
Cleaned up the piston and inside the solenoid housing with some wire wool, used a bit of copper grease (anti sieze) on the piston and reassembled.
Worth checking the rest of the starter over at the same time.
Jobs a goodun, no probs since.
If you're willing and confident to strip it down you'll need an impact driver to get the three screws holding the solenoid out as they will have corroded, spray plenty of releasing agent on them first.
I'm going to do the same on my other starter and keep as a spare.

If there is no click from the starter mate, then the solenoid isn't engauging, ruling the starter itself out.
