Interminnent no start, Interminnent no start Options

[valerit1]

Began recently - upon a key turn - just warning lights and silence - no starter turning. Next turn may start fine. Battery is new.
No other issues. Happened after running, never cold - but unsure about a connection. Just like - one time there is no
starter connection, next time - OK. Any ideas greatly appreciated. Thanks!

Okay. My son has been using my '96 Jeep Grand Cherokee since I bought my Celica last October. He called me yesterday to say the Jeep would start. When I came home, there was a bit of extra play when turning the ignition key. All the dash loghts came on, but the starter wouldn't engage. He told me it happened a few times before, so I took out the ignition switch assembly and pulled the lock cylinder out. There is a notch on the cylinder that fits over a bump that engages the starter. That notch had become rounded (should be square), and had opened up quite a bit. Both parts were replaced, since the shavings from the cylinder could be heard when the switch assembly was shaken, and the Jeep started right up. Worth having a look, and it's not too difficult to remove a Celica's ignition key cylinder. Jeep used Torx screws and bolts on nearly everything, and the ignition required tamper-proof Torx drivers. Like a car thief wouldn't have those.....
