raj49 Posted June 2, 2010 Share Posted June 2, 2010 Just picked up this LS400. The engine turns over but no start. The radiator got bent and hit the water pump pulley and so the belt obviously is off and not working the alternator. Would the engine still start or is this a fail safe or something else entirely? The battery is brand new 12.7 Volts. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
steve2006 Posted June 2, 2010 Share Posted June 2, 2010 The water pump is driven off the cam belt and is hidden behind the timing belt covers,if the cam belt is off and you tried to start it won't as the timing will be wrong,if you mean the serpentine belt that's different. You need air (which unless there is a serious blockage you will have),fuel and a spark for an engine to fire so check for these 1st. If there is damage to the front of the engine check the distributor caps as these may have been damaged and wiring in the damaged area.

I meant the radiator fan pulley is bent and the serpentine belt is off. So the engine should still start, right? Im gonna check spark.

Like Steve said, air shouldn't be a problem, so check spark and fuel. Quote Link to comment Share on other sites More sharing options...

No. If the anti theft is engaged, it won't even turn over, much less start for a second. I'd go back to the beginning and take the air filter out and leave the airbox open when you try to start it. Then I'd check that you are getting fuel, then spark. Quote Link to comment Share on other sites More sharing options...
