You need to find out if that cylinder has spark. If so, then move on to checking to see if the injector is being triggered by the ECU. If so, then you need to check for compression in that cylinder.

Pretty basic stuff here. You need fuel, compression and spark for a gasoline powered engine.

Post by: DasPoop on July 30, 2010, 07:39:30 AM: take it off and see if its just one valve. there cheap enough to replace. that way you dont sell your head cheap then have to buy a good one. just fix what you have got.
