Default 1998 v70 2.4 bi-fuel intermittent non-crank

Hello.
Recently purchased this vehicle with 80,000km.
Came with 3 keys and a central locking remote.
Is there a common issue with these not cranking intermittently? First thought it was a 'dud' key but happens with all keys. No noise from starter, just won't crank on start like the lever is not in 'P' position. Of course it doesn't happen when you show the problem to somebody lol
Cheers

There is on the automatic transmission models, due to the starter contacts in Park and Neutral. The switch is mounted right on the transmission.. I suppose contacts in the ignition switch are also a problem, but it seems like the starter contacts aren't complained about as much. More like the contacts for other items in "run" aren't lining up just right and you start jiggling the switch in "run" to get everything on.

These are super simple issues obviously, you may have something entirely worse going on.

3 things to try:

1) the shifter row (key postion to unlock shifter, engine off, shift from park to low to park 10-20 times fast. This can be enough to scuff up the contacts in the PNP switch to get it to behave
2) check battery terminals and cables to the starter, also check battery voltage - with the engine off it should be 12.5V or higher. with the engine running it should be 14V or higher
3) do you hear a click or see the lights dim when turning the key on a failed start? This would suggest the starter motor is drawing current but may have a "dead spot" or the solenoid is not flying out. Odd as it may seem, sometimes hitting the starter with a mallet can be enough to get it to engage.

Ended up being the starter relay. A cheap fix this time round 😉
