Title: G40 died for 5 mins
Post by: Jezza-7 on March 14, 2010, 06:15:39 pm

Was driving back and was going through some country roads so i thought i would have a little fun. After the country roads finished i was back on main raod and accelerated quickly and as i changed from 1st to 2nd gear and accelerated it died. Pulled over to the side of the road and looked underneath for oil loss or fuel loss but there was nothing. Tried to start at it was giving me nothing. Tried a few more times then thought about calling the AA. After 5 mins it started and ran fine all the way back home. Anyone have any idea what it could be?

Ok, i have just done resistance checks on ignition coil and injectors, all within limits.

Hall sender? Im not 100% sure on this, i know where it is but what is its purpose.

Its the plug that goes into a connection just above distributor.

the hall sender is inside the dizzy, its a part of the dizzy infact.

Mine failed on me when i was at the pod, died for a while and then came back to life and then died again on the way home several more times.

That sounds like what my problem is. It has cut out 3 times but only for 1/2 a second and then today it completly cut out.

Thanks for the help Robin.

Are they easy enough to replace? Not much info in the haines manual.

its 100% the hall sender, mine did the same, the engine cuts out every so often and then kicks back in after a second or so. when it started to play up it gave up ghost for 10mins and then was ok.

its an arse to change in the dizzy, i ended up buying a 2nd hand dizzy as i broken the new hall sender fitting it!
