My 97 gmc sierra 2500 4x4 has the 5.7 vortec 350. I changed my head gaskets . Got it all back together won't start.....
My valves are adjusted to 1/2 turn past 0
lash . My #1 cylinder is on tdc on
compression stroke & at 0 on dampener
mark. Distributer pointing a hair advanced
of #1 mark on housing . I have good fuel in
all cylinders good compression in all
cylinders and spark at all plugs . Still not
firing up ! I rechecked all plug ins and every
fuse still nothing. ANY IDEAS ? DRIVING ME
CRAZY lol
