Im not grtting ignition spark on # 4,5,6 cyls,

thank you for your reply.yes the no spark is on the same bank drivers side.tested each coil,tested good on ohms,not getting voltage to coils.the engine came to me torn down on the left bank head,cams,etc.I got it all together according to alldata instructions step by step,I turned the crank by hand 4 revolutions all went smooth. I started the engine and found # 4,5,6 cyl wasnt firing but is getting fuel.ran a compression test found 185 lbs on all cylinders.Replaced the cam sensor on that side still no firing on 4,5,6,bank

if you have access to alldata you should be able to find a troubleshooting guild for no spark. You have started in the right direction. Check to make sure the power is getting to the coil pack. The continue "upstream" from the coil until you find power. I can see 1 coil not working but not 3 all on the same side. Im thinking you have a problem closer in the direction of the computer. I dont suspect the computer mainly because you are getting some spark. Just follow that wire harness. it has to be there. I did an intake job once and pinched some wires to an injector. It got no signal so I has a miss. Simple mistake. Once I started following the wire I found the problem. Im hoping it is nothing more than this.
