Ok, this might be a bit long winded, so I apologise in advance but I need everyone to know the full details so they can make an accurate assessment of my dilemma and offer advice accordingly.
Rewind 3 weeks ago.
I did a transmission service and it all went off without a hitch. Had a slight fluid drama with the correct amount but sorted that out with no ill effects.
Fast forward to last week.
I park my car at night. Come outside in the morning and it won't crank. Everything works, just no crank. So I left it sit for a couple of hours and did a bit of research on the net. Someone suggested trying another key, so I grab my spare, go outside and what do you know, it starts! So, I drive around for the past week using the spare key .... No dramas.
3 days ago, I go to start my car and no crank again. No biggie, I go and grab my other key, put in in and it still won't crank. Everything else works except for cranking. I noticed when I turned the key to the cranking position (and get nothing) the clock on the stereo display goes out.
Flat battery I thought, so I grab the other commodore, and try jump starting it ...... nothing.
I checked the error codes and get code 12 ... All normal still no crank.
I strip the shifter assembly plastics and check the safety switch. All good, still no crank.
I strip the ignition down, make sure the key is touching the metal ring and trying starting it with a screwdriver in the black plastic piece, still no crank.
I check all fuses, perfect. I check all relays ... perfect.
Is it possible that during the transmission service I might have bumped another neutral safety switch located on either the outside of the box or inside the pan somewhere? I wiped the wiring assembly down with a rag to stop getting dripped on with transmission fluid, but don't think I loosened anything or unplugged anything.
Anyone got any ideas on what the problem might be? Is there another neutral safety switch on the gearbox itself? Someone else on here said there was, but couldn't tell me if it was inside or outside, passenger side or drivers side. Any help would be greatly appreciated as my son goes into hospital for an operation on Tuesday and we really need 2 cars working.
Cheers all, I eagerly await your replies.
