I have a 2005 Buick LeSabre custom with a 3.8 vehicle will not start fuel pump works fuel pressure is where it needs to be on the fuel rail spark plugs are wet with gas good battery in it power at the fuse box power at all the fuses power down at the starter motor rolls over and tries to crank but won't start it has three coil packs each coil pack runs two cylinders each one of those are working and they're a spark at each spark plug I sprayed starter fluid in the air box just as a second confirmation that I already knew for my fuel pressure gauge still no start I believe that it has a bad crank or a cam sensor because it has spark it has a good battery it has fuel spark plugs are wet with fuel tried spraying starter fluid but when you hold the key down and try to start it about every five or six seconds you might get one little pump like it's trying to start
