Crank but no start Hey guys,
new 5.3, fitech ultimate LS setup.
Heads, cam, flat tops, etc
motor cranks and blows fireballs out the exhaust, like it’s out of time..
we did swap valve covers, from driver to pass to put the fill cap on the easier to access side, are the coil pack setups specific to each side?
Tried a second crank sensor from another 5.3 no different... thinking maybe the chain is a tooth off?
Any other ideas?

I'm assuming you've got some kind of PCV bypass (maybe an LS6 cover?) since the hoses on the valve covers are specific to each side...
Coil packs should be universal. You can always swap the coil packs to the other side to see if it makes a difference. Bracket just unbolts from the valve cover.
I'm assuming this is some kind of swap? ie, not a vette or fbody or truck?

Swapped the coil racks back, Cranked 3-4 more times and Viola started right up.. FITECH said sometimes, it takes extended cranking for the ECU to get cam/Crank sensors to phase up Also.. Good info for anyone looking at their kits in the future.
Ive got a comp XR275HR in the Motor, And the idle sounds super smooth... Shouldn't i get some chop, Especially with Open headers right now..?
Yes its a swap, In our race jeep.
