my LTX8 been runnin great for so long i forgot about it.

then no warning or change of anything it shows on wideband very lean when it used to go full rich ,like 10.5-10.9.

seems as tho the secondaries aint comin on, w/b shows 14.5 as boost comes up, so i been stayin out of boost ,till i get it straight. no power ethier.

Question;; where to start first?

stage is at 3000rpm , 5" vacuum, and you could feel secs. come on, w/b would show it BUT not workin now. just goes lean.

bumpstart

set it to cyl= 0 in screen 31 config ( test mode ) ,, listen with a screwdriver handle in your ear that all injectors click,, and that all leads fire
then if OK
fuel pump static pressure test , pump volts check and dead headed ( max ) pressure check ,, change the fuel filter,, service the injectors
