VR 94 - Engine turns but won't start

[mar06mir]

Hi,

The car refused to start tonight although the engine was turning each time. Fuel pump works, can hear it and feel the fuel hose swell, battery and starter work ok, high tension cables are fine, fuel pressure regulator relatively new (6 mths) and all other systems look ok. The only thing that puzzles me are the wipers which came on evey time I turned the ignition on.

Eventually the engine started and I managed to drive myself home, some 30km, with no problems but the wipers worked most of time and couldn't switch them off no matter what I tried. They stopped by themselves for the last 10min or so. When I got home I turned the engine off but couldn't start it again although the wipers didn't operate by themselves any more.

Any clues? Must be electrical, perhaps affected by the wet weather. Could it be body control module? How to test it?

If the wipers were going weird, and u started it and then it wouldnt go, that sounds like it actually IS the battery.

This happened with my VN Calais once. It was sat in a carpark by my house all night coz i couldnt drive it home. Next morning go down their for a cruise and it wouldnt start. The engine turned over after a long delay, and their was a loud constant clicking sound, and the lights and wipers, and electric windows were doing their own thing - sometimes working, sometimes not, sometimes just turning off and on themselves.

After a whole day of trying to figure it out with mates it turned out to be the battery. I think it had got wet overnight and also had run abit flat. Maybe u could try just charging it full and then giving it another go. If that fails then im stuck, im only 17 so not a mechanical genious atm!

In the morning it wouldn't crank at all. The remote didn't work and the interior light went crazzy. Self diagnosis showed code 31 - faulty theft deterrent. Opended the fuse lid, removed the vent duct above it and checked the BCM connectors. Had a better look around and found signs of moisture. Removed the BCM and it was wet and the foam / fabric above was completely soaked. Some water got into the BCM as well. Later I found a leak under the RH side of the windscreen. Fixed that and took the car to Holden (managed to get it going after leaving the key on for 40min). They said they would charge me $250 for the new BCM and $160 for one new key pad. A total rip off, especially for the key pad (just a month ago I both two new keys from Mr Mint for $175). I couldn't find a second hand BCM anywhere, including wreckers.
