oil light and engine stall

Does the engine still turn over on the starter motor? If it does then at least the engine is not seized.

I would be inclined to change the oil filter and the oil pressure switch and try again. Might also be a good idea to change the oil, just in case it got cooked.

Did you notice if the engine temp over-heated?

hi biggy yes she does, got me switch today,going to drain the oil sunday remove the sump and have a good clean out also changing the filter, fingers crossed. didnt notice the temp sorry, cheers matt
